Brody is going to invest $350 and leave it in an account for 18 years. Assuming the interest is compounded daily, what interest rate, to the


neatest tenth of a percent, would be required in order for Brody to end up with $790?

Answers

Answer 1

Brody would need an interest rate of 4.5% compounded daily.

How to calculate interest rate of investment?

We can use the compound interest formula to solve the problem:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

where:

A = final amount of money ($790)

P = initial investment ($350)

r = interest rate (unknown)

n = number of times interest is compounded per year (365, since interest is compounded daily)

t = time in years (18)

So, we can plug in the given values and solve for r:

[tex]790 = $350(1 + r/365)^(^3^6^5^1^8^)[/tex]

[tex]2.25714 = (1 + r/365)^(^3^6^5^1^8^)[/tex]

[tex]ln(2.25714) = ln[(1 + r/365)^(^3^6^5^1^8^)][/tex]

[tex]ln(2.25714) = 18ln(1 + r/365)[/tex]

[tex]ln(2.25714)/18 = ln(1 + r/365)[/tex]

[tex]e^(^l^n^(^2^.^2^5^7^1^4^)^/^1^8^)^ =^ 1^ +^ r^/^3^6^5[/tex]

[tex]1.0345 = 1 + r/365[/tex]

[tex]r/365 = 0.0345[/tex]

[tex]r = 12.5925[/tex]

Therefore, Brody would need an interest rate of approximately 12.6% (rounded to the nearest tenth of a percent) in order to end up with $790 after 18 years with daily compounding.

The slope of desired parallel line is undefined.

How to find slope of a line?

Given two points [tex](-4, 3)[/tex] and [tex](-4, 7)[/tex], we can see that both points have the same x-coordinate, which means that they lie on a vertical line parallel to the y-axis. Since the slope of a vertical line parallel to the y-axis is undefined, we can say that the slope of line m is undefined.

To find the slope of a line that is parallel to line m, we can use the fact that parallel lines have the same slope. Since the slope of line m is undefined, any line parallel to it will also have an undefined slope.

check answer

Answers

Since 24.8 minutes is less than 36.4 minutes, you would still meet your goal because your total running time added to your swimming and biking times is less than 100 minutes.

The inequality that represents how many minutes x you can take to finish the running event and still meet your goal is: 18.2 + 45.4 + x < 100. To solve for x, we need to isolate it on one side of the inequality:

18.2 + 45.4 + x < 100
x < 100 - 18.2 - 45.4
x < 36.4

Therefore, you can take no more than 36.4 minutes to finish the running event and still meet your goal of finishing with an overall time of less than 100 minutes.

For question 3, if it takes 8 minutes to run a mile and the running event is 3.1 miles long, it would take you 24.8 minutes to complete the running event. This time is less than the maximum time of 36.4 minutes that you can take to still meet your goal, so yes, this time would allow you to reach your goal.

For question 4, the statement is just reiterating the goal mentioned in the first sentence, that your overall time for all three events must be less than 100 minutes. It confirms that you have met your goal by stating that your total running time added to your swimming and biking times is less than 100 minutes.

If you want to put a border around a rectangular room what steps would you use to find the length of border needed

Answers

To find the length of border needed to put around a rectangular room, you can follow these steps:

Measure the length and width of the room using a tape measure or ruler. Let's say the length is L and the width is W.

Determine the type and width of the border you want to put around the room. Let's say you want to use a wallpaper border that is 6 inches wide.

Calculate the length of the border needed for the top and bottom of the room.

This can be done by adding the width of the room to twice the width of the border. So the length of the top and bottom borders would be:

Length of top/bottom borders = 2(W + 6 inches)

Calculate the length of the border needed for the left and right sides of the room. This can be done by adding the length of the room to twice the width of the border. So the length of the left and right borders would be:

Length of left/right borders = 2(L + 6 inches)

Add up the length of all four borders to get the total length of border needed to put around the room:

Total length of border = 2(W + 6 inches) + 2(L + 6 inches)

Simplifying the above equation, we get:

Total length of border = 2L + 2W + 24 inches

So the total length of border needed to put around the room is 2L + 2W + 24 inches.

The path r(t)=(t) i+(3t2+5) j describes motion on the parabola y=3x2+5. Find the particles velocity and acceleration vectors at t=5

Answers

The particle's velocity vector at t=5 is v(5) = 1i + 30j, and the acceleration vector at t=5 is a(5) = 0i + 6j.

To find the particle's velocity, we take the derivative of the path r(t) with respect to time:

v(t) = r'(t) = i + 6t j

Substituting t=5, we get:

v(5) = 1i + 30j

To find the particle's acceleration, we take the derivative of the velocity with respect to time:

a(t) = v'(t) = 0i + 6j

Substituting t=5, we get:

a(5) = 0i + 6j

Note that the acceleration vector is constant, which is expected since the particle is moving along a parabolic path, and the curvature of the path remains constant.

Toby created a sculpture for art class using different-sized cubes. the smallest cube is 1.5 inches along each edge. the largest cube is 7.5 inches along each edge. how many of the smallest cubes would it take to fill the largest cube

Answers

It would take approximately 125 of the smallest cubes to fill the largest cube.

To determine the number of the smallest cubes that would fit inside the largest cube, we need to calculate the volume of both cubes.

The volume of a cube can be calculated by multiplying the length of one side by itself three times (since a cube has three equal sides). So, the volume of the smallest cube would be 1.5 x 1.5 x 1.5 = 3.375 cubic inches.

The volume of the largest cube can be calculated in the same way. The length of one side is 7.5 inches, so the volume would be 7.5 x 7.5 x 7.5 = 421.875 cubic inches.

To determine how many of the smallest cubes would fit inside the largest cube, we need to divide the volume of the largest cube by the volume of the smallest cube. So, 421.875 divided by 3.375 equals approximately 125.

As an estimation we are told 3 pounds is four euros convert 16 euros to pounds

Answers

As an estimation of the exchange rates, 16 Euros is approximately equal to 12 Pounds.

To convert Euros to Pounds, we first need to determine the conversion rate between these two currencies. From the information provided, we know that 3 Pounds is approximately equal to 4 Euros. Using this information, we can establish a conversion factor by dividing 3 Pounds by 4 Euros:

Conversion factor = 3 Pounds / 4 Euros = 0.75 Pounds per Euro

Now that we have the conversion factor, we can use it to convert 16 Euros to Pounds. To do this, we simply multiply the amount in Euros (16) by the conversion factor (0.75 Pounds per Euro):

16 Euros * 0.75 Pounds per Euro = 12 Pounds

So, as an estimation, 16 Euros is approximately equal to 12 Pounds. Keep in mind that exchange rates between currencies can fluctuate over time, so it's always a good idea to double-check the current rate before making any financial transactions.

Answers

Hunter needs 3 ounces of seeds and 7 ounces of dried fruit, which will cost him $22 in total. The system of equations is 1.5x + 2.5y = 22 and x + y = 10. The solution is (x,y) = (3,7).

The total amount of snack mix required is 10 ounces. So, the sum of the amount of seeds and dried fruit should be 10.

x + y = 10 ---(Equation 1)

The cost of seeds is $1.50 per ounce and the cost of dried fruit is $2.50 per ounce. The total cost of snack mix should be $22.

1.50x + 2.50y = 22 ---(Equation 2)

To solve the system, we can use substitution method. Solving Equation 1 for y, we get

y = 10 - x

Substituting this value of y in Equation 2, we get

1.5x + 2.5(10 - x) = 22

Simplifying and solving for x, we get

1.5x + 25 - 2.5x = 22

-x = -3

x = 3

So, Hunter needs 3 ounces of seeds and 7 ounces of dried fruit to make 10 ounces of snack mix with a total cost of $22.

Joe and Tommy are playing a game of chicken. Tommy has a mass of 91 kg, Joe has a mass of 97 kg. Tommy is running towards Joe with a velocity of 5 m/s, Joe is running towards Tommy with a velocity of 6 m/s. Neither "chickens" out. After collision, Joe is standing still. How fast does Tommy bounce off Joe? Round to four decimal places

Answers

Tommy bounces off Joe at a speed of 5.9451 m/s after the collision.

We need to use the conservation of momentum, which states that the total momentum of a closed system remains constant. In this case, the closed system is the two players, Joe and Tommy.

We can start by calculating the initial momentum of the system, which is given by:

[tex]p_{initial} = m_{Tommy} * v_{Tommy} + m_{Joe} * v_{Joe}[/tex]

where m_Tommy and m_Joe are the masses of Tommy and Joe, respectively, and v_Tommy and v_Joe are their initial velocities.

Plugging in the given values, we get:

[tex]p_{initial} = 91 kg * 5 m/s + 97 kg * 6 m/s[/tex]

p_initial = 1123 kgm/s

After the collision, Joe is standing still, which means his velocity is zero. Let's call Tommy's velocity after the collision v_Tommy', which we need to find.

The final momentum of the system is given by:


[tex]p_{final} = m_{Tommy} * v_{Tommy'} + m_{Joe} * 0[/tex]

where we set Joe's velocity to zero since he's standing still.

Since the momentum is conserved, we can equate p_initial and p_final:

p_initial = p_final

[tex]m_Tommy * v_Tommy + m_Joe * v_Joe = m_Tommy * v_Tommy'[/tex][tex]m_{Tommy} * v_{Tommy} + m_{Joe} * v_{Joe} = m_{Tommy} * v_{Tommy'}[/tex]

91 kg * 5 m/s + 97 kg * 6 m/s = 91 kg * v_Tommy'

Solving for v_Tommy', we get:

[tex]v_{Tommy'} = (91 kg * 5 m/s + 97 kg * 6 m/s) / 91 kg[/tex]

v_Tommy' = 5.9451 m/s (rounded to four decimal places)


In summary, we used the conservation of momentum to calculate the velocity of Tommy after bouncing off Joe. We found that he bounces off Joe at a speed of 5.9451 m/s.

To find the missing measures of a rectangle, we should know that all rectangles have four sides, and each side has a length.

If we have a quadrilateral like a rectangle with four angles, all the angles must be 90 degrees. We need to use the properties of rectangles to find the missing measures of a rectangle. We will find the length of each side first. The length of all sides of a rectangle should be the same. Then, we will calculate the area of the rectangle by multiplying the length of one side by the length of the other side.

Finally, to find the missing measures we will use the Pythagoras Theorem. The Pythagoras Theorem states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. Using this theorem, we can find the length of the hypotenuse of the rectangle.

y = 3x⁴ + 4x³
Find the
1) Domain
2) Intercepts
3) Asymptotes
4) Symmetry
5) Critical Points
6) Maxima/Minimum
7) Concavity

Answers

1)  The domain of Y = 3x⁴ + 4x³ is (-∞, ∞).

2) The x-intercepts are (0, 0) and (-4/3, 0) and the y-intercept is (0, 0)

3)  The horizontal asymptote is y = infinity.

4) Function does not exhibit any symmetry with respect to the y-axis or origin.

5)  The critical points are x = 0 and x = -1.

6)  The critical points are x = 0 and x = -1.

7) The function is concave down on the interval (-∞, -2/3) and concave up on the intervals (-2/3, 0) and (0, ∞).

How to find domain?

1) The domain of a polynomial function is all real numbers, so the domain of Y = 3x⁴ + 4x³ is (-∞, ∞).

How to find Intercepts?

2) To find the x-intercepts, we set Y equal to zero and solve for x:

0 = 3x⁴ + 4x³

0 = x³(3x + 4)

x = 0 or x = -4/3

Therefore, the x-intercepts are (0, 0) and (-4/3, 0).

To find the y-intercept, we set x equal to zero and solve for Y:

Y = 3(0)⁴ + 4(0)³

Y = 0

Therefore, the y-intercept is (0, 0).

How to find Asymptotes?

3) Polynomial functions do not have vertical asymptotes. However, as x approaches positive or negative infinity, the function approaches infinity. Therefore, the horizontal asymptote is y = infinity.

How to find Symmetry?

4) The function Y = 3x⁴ + 4x³ is neither even nor odd. Therefore, it does not exhibit any symmetry with respect to the y-axis or origin.

How to find Critical Points?

5) To find the critical points, we take the first derivative of Y and set it equal to zero:

Y' = 12x³ + 12x²

0 = 12x²(x + 1)

Therefore, the critical points are x = 0 and x = -1.

How to find Maxima/Minimum?

6) To determine whether the critical points are maxima or minima, we take the second derivative of Y and evaluate it at each critical point:

Y'' = 36x² + 24x

At x = 0, Y'' = 0, which means that the second derivative test is inconclusive. To determine whether x = 0 is a maxima or minima, we look at the sign of the first derivative to the left and right of the critical point. We find that Y' is negative to the left of x = 0 and positive to the right, so x = 0 is a local minimum.

At x = -1, Y'' = 12, which is positive. Therefore, x = -1 is a local minimum.

How to find Concavity?

7) To determine the concavity of the function, we look at the sign of the second derivative:

Y'' = 36x² + 24x

When Y'' > 0, the function is concave up, and when Y'' < 0, the function is concave down.

At x < -2/3, Y'' is negative, so the function is concave down.

At -2/3 < x < 0, Y'' is positive, so the function is concave up.

At x > 0, Y'' is positive, so the function is concave up.

Therefore, the function is concave down on the interval (-∞, -2/3) and concave up on the intervals (-2/3, 0) and (0, ∞).

The domain of a function is the set of all possible inputs for the function. In this case, the function is h(t)=80t-16t². Since time cannot be negative, the domain of h(t) is all real numbers greater than 0. Then,  required answer for the provided question is Option A.

To evaluate the maximum height reached by the rocket, now to calculate the derivative of the function h(t)=80t-16t² and set it equal to zero.
This will provide  the time at which the rocket reaches its maximum height. Therefore, here we can place  time back into the original function to evaluate the maximum height.
h(t)=80t-16t²
h'(t)=80-32t

32t=80
t=2.5 seconds

Then the rocket touches its maximum height after 2.5 seconds.
To evaluate the maximum height, place t=2.5 into h(t):

Answers

All real numbers will be the function's domain. D is the right answer in this case.

What are domain and range?

The range of values that we are permitted to enter into our function is known as the domain of a function.

The x values for a function like f make up this set(x).

A function's range is the collection of values it can take as input.

After we enter an x value, the function outputs this sequence of values.

The range refers to all potential values of y, and the domain refers to all conceivable values of x.

Let a be the leading coefficient and the parabola's vertex be the point (h, k).

The parabola's equation will then be provided as,

y = a(x - h)² + k

The graph shows where the vertex of the parabola will be. (-1.5, -4.5). The equation is then presented as:

y = a(x + 1.5)² - 4.5

Therefore, all real numbers will be the function's domain. D is the right answer in the case.

Evaluate the line integral JF. dr where F = (-2 sin x, 2 cos y, 6zx) and C is the path given by r(t) = (3t^3, -3t^2, -3t) for 0 <= t <= 1

Answers

To evaluate the line integral JF.dr, where F = (-2 sin x, 2 cos y, 6zx) and C is the path given by r(t) = (3t^3, -3t^2, -3t) for 0 <= t <= 1, we first need to parameterize F and r in terms of t.

For F, we have:

F = (-2 sin x, 2 cos y, 6zx) = (-2 sin (3t^3), 2 cos (-3t^2), 6(3t^3)(-3t)) = (-2 sin (3t^3), 2 cos (3t^2), -54t^4)

For r, we already have the parameterization:

r(t) = (3t^3, -3t^2, -3t)

Now we can use the formula for the line integral:

JF.dr = ∫(F dot dr)

= ∫(-2 sin (3t^3) dx + 2 cos (3t^2) dy - 54t^4 dz)

= ∫(-18t^2 cos (3t^2) + 18t^2 cos (3t^2) - 54t^4) dt

= ∫(-54t^4) dt

= -9t^5 + C

Evaluating this expression for t = 1 and t = 0, we get:

JF.dr = (-9(1)^5 + C) - (-9(0)^5 + C)

= -9 + 9

= 0

Therefore, the line integral JF.dr evaluated along the path given by r(t) = (3t^3, -3t^2, -3t) for 0 <= t <= 1 is equal to 0.

What is the amount of carrying charges for a $10,000 for college if there is a 5% down payment, apr of 10%, and a 36-month repayment period?

Answers

The amount of carrying charges for a $10,000 college loan with a 5% down payment, a 10% APR, and a 36-month repayment period is approximately $1,571.44.

To calculate the amount of carrying charges for a $10,000 college loan with a 5% down payment, a 10% annual percentage rate (APR), and a 36-month repayment period, follow these steps:
1. Determine the down payment: 5% of $10,000 = $500.
2. Subtract the down payment from the loan amount: $10,000 - $500 = $9,500. This is the principal loan amount.
3. Calculate the monthly interest rate: 10% APR / 12 months = 0.833% or 0.00833 as a decimal.


4. Calculate the monthly payment using the loan payment formula: P = r * PV / (1 - (1 + r)⁻ⁿ), where P is the monthly payment, r is the monthly interest rate, PV is the present value (principal loan amount), and n is the number of monthly payments. P = 0.00833 * $9,500 / (1 - (1 + 0.00833)⁻³⁶) = $307.54.
5. Determine the total amount paid over the loan term: Monthly payment * Number of monthly payments = $307.54 * 36 = $11,071.44.
6. Calculate the carrying charges: Total amount paid - Principal loan amount = $11,071.44 - $9,500 = $1,571.44.

A museum charges 12. 50 admission Each special  sip it cost extra 2. 00 Write an expression that represents the cost in dollars of admission to the museum including admittance to n special exhibits.

Answers

The expression that represents the cost, in dollars, of admission to the museum including admittance to n special exhibits can be written as 12.50 + 2n

Here, 12.50 is the base admission cost without any special exhibit, and 2n represents the cost of n special exhibits, where each exhibit costs an extra $2.00.

By multiplying the number of special exhibits, n, by $2.00, we get the total cost of special exhibits, which we can then add to the base admission cost to get the total cost of admission to the museum including admittance to n special exhibits.

For example, if someone wants to visit the museum and see 3 special exhibits, the cost of admission would be:

12.50 + 2(3) = 12.50 + 6 = $18.50

Therefore, the expression 12.50 + 2n represents the total cost of admission to the museum including admittance to n special exhibits.

The Ferrells save $150 each month for their next summer vacation. Write an equation that they can use to find y, their savings, after x months

Answers

The equation that represents the Ferrells' savings after x months is y = 150x

In this equation, x represents the number of months that the Ferrells have been saving, and y represents the amount of money they have saved after x months.

The coefficient 150 represents the amount of money the Ferrells save each month, and it is multiplied by the number of months x to get the total savings y. For example, after 5 months of saving, the Ferrells would have saved:

y = 150(5) = $750

This equation can be used to calculate their savings at any point in time, as long as they continue to save $150 each month.

Anissa said that distance, d, could be either an independent or dependent variable Explain Anissa's statement. Distance, d, could be an) Choose. Variable because it affects the amount of time that someone has traveled. Distance, d, could also be a(n) Choose variable because it is affected by the speed traveled. ​

Answers

Anissa's statement is correct.

The classification of distance, d, as either an independent or dependent

variable depends on the context in which it is used.

Distance as an independent variable:

In this case, distance, d, is considered an independent variable because it

affects the amount of time someone has traveled.

When we are interested in studying how the distance traveled affects

other variables, such as time or fuel consumption, we treat distance as the

independent variable and manipulate it to observe its impact on the

dependent variables.

For example, if we conduct an experiment to measure the time it takes to

travel a certain distance under different conditions (e.g., different speeds or

modes of transportation), we would vary the distance as the independent

variable while keeping other factors constant.

In this scenario, distance is the independent variable, and time is the

dependent variable.

Distance as a dependent variable:

On the other hand, distance, d, can also be considered a dependent

variable when it is affected by the speed traveled.

In this case, speed becomes the independent variable, and distance is

dependent on the speed at which an object or person travels.

For instance, if we investigate how the speed of a vehicle affects the

distance it can travel within a given time, we would manipulate the speed

as the independent variable and observe the corresponding changes in

distance.

Here, distance is the dependent variable, and speed is the independent

variable.

In summary, Anissa's statement is accurate because distance, d, can be

considered an independent variable when it affects other factors such as

time, and it can also be a dependent variable when it is influenced by

factors like speed.

The designation of distance as independent or dependent depends on the

specific context and the relationship it shares with other variables in the

given situation.

Kyla has a concrete patio in the shape of a semi-circle. What is the area of the patio? Use 3. 14 for π. It’s s i circle and is 6. 75 ft and in squared

Answers

The area of the semi-circle patio is approximately 17.91 square feet.

To find the area of the semi-circle patio, we need to use the formula for the area of a circle, which is A = πr^2, where π is 3.14 and r is the radius of the circle.

However, since we only have a semi-circle, we need to divide the result by 2 to get the area of the half-circle.

In this case, the radius of the semi-circle is half of the diameter, which is given as 6.75 feet. So, the radius is 6.75/2 = 3.375 feet.

Now, we can plug this value into the formula:

A = (π)(3.375)^2 / 2

A = (3.14)(11.390625) / 2

A = 35.81765625 / 2

A = 17.908828125 square feet

Therefore, the area of the semi-circle patio is approximately 17.91 square feet.
