Dominick and Ryan both invest $6,500 into savings accounts that earn 6. 8% interest. If Dominicks account earns compound interest and Ryan's earns simple interest, how much more interest will Dominick have earned after 10 years?

Answers

Answer 1

Dominick has earned $6,465.55 - $4,420.00 = $2,045.55 more interest than Ryan after 10 years.

How to find the earned  interest?

To solve this problem, we can use the formulas for compound interest and simple interest.

Compound interest formula:

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

Where:

A = the amount after time t

P = the principal

r = the annual interest rate

n = the number of times the interest is compounded per year

t = time in years

Simple interest formula:

I = Prt

Where:

I = the interest earned

P = the principal

r = the annual interest rate

t = time in years

Using the compound interest formula for Dominick's account:

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

A = 6500(1 + 0.068/365)^(365*10)

A ≈ $12,965.55

Using the simple interest formula for Ryan's account:

I = Prt

I = 65000.06810

I = $4,420.00

Dominick's account has earned: $12,965.55 - $6,500 = $6,465.55 in interest.

Ryan's account has earned: $4,420.00 in interest.

Therefore, Dominick has earned $6,465.55 - $4,420.00 = $2,045.55 more interest than Ryan after 10 years.

A 10-foot ladder is leaning against a wall. If we pull the ladder away from the wall at a rate of 8 ft/s how fast is the top of the ladder moving down the wall when the bottom of the ladder is 8ft from the wall? (Enter an exact answer.) Provide your answer below: The ladder is moving down the wall at a rate of__ feet per second

Answers

The top of the ladder is moving down the wall at a rate of 32/3 feet per second when the bottom of the ladder is 8 feet from the wall.

Let's denote the distance between the bottom of the ladder and the wall as x, and the distance between the top of the ladder and the ground as y. Since the ladder is leaning against the wall, we have a right triangle formed by the ladder, the wall, and the ground.

We know that the ladder has a length of 10 feet, so by the Pythagorean theorem, we have:

x^2 + y^2 = 10^2

Differentiating both sides with respect to time t, we get:

2x(dx/dt) + 2y(dy/dt) = 0

We want to find the rate of change of y (the speed at which the top of the ladder is moving down the wall), when x = 8 ft and dx/dt = 8 ft/s. We can substitute these values into the equation above and solve for dy/dt:

2(8)(8) + 2y(dy/dt) = 0

Simplifying this equation, we get:

dy/dt = -64/y

Now we need to find the value of y when x = 8 ft. We can use the Pythagorean theorem again:

x^2 + y^2 = 10^2

8^2 + y^2 = 100

y^2 = 100 - 64

y = sqrt(36) = 6 ft

Substituting this value of y into our equation for dy/dt, we get:

dy/dt = -64/6 = -32/3 ft/s

Therefore, the top of the ladder is moving down the wall at a rate of 32/3 feet per second when the bottom of the ladder is 8 feet from the wall.

Hunter assumed he would only get 64 problems correct on his test, but he actually got 78 correct, So his percent error is 18%.

To calculate Hunter's percent error, we'll use the given formula:

Percent error = ((Prediction - Actual) / Actual) x 100

Prediction = 64 (the number of problems Hunter assumed he would get correct)
Actual = 78 (the number of problems he actually got correct)

Now, plug in the values:

Percent error = ((64 - 78) / 78) x 100
Percent error = (-14 / 78) x 100
Percent error ≈ -17.95%

Since percent error is typically expressed as a positive value, we can round to the nearest percent and report it as:

Alan buys a bag of cookies that contains 5 chocolate chip cookies, 5 peanut butter cookies, 5 sugar cookies and 9 oatmeal cookies. What is the probability that Alan randomly selects a chocolate chip cookie from the bag, eats it, then randomly selects a peanut butter cookie? Express you answer as a reduced fraction

Answers

The probability of selecting a chocolate chip cookie on the first draw is 5/24, since there are 5 chocolate chip cookies in the bag out of a total of 24 cookies. After eating the chocolate chip cookie, there are 23 cookies left in the bag, including 5 peanut butter cookies. So the probability of selecting a peanut butter cookie on the second draw is 5/23.

To find the probability of both events happening, we multiply the probabilities:

P(select chocolate chip then peanut butter) = P(select chocolate chip) × P(select peanut butter after selecting chocolate chip)
= (5/24) × (5/23)

We can reduce this fraction by finding the greatest common factor of the numerator and denominator, which is 1 in this case:

P(select chocolate chip then peanut butter) = (5/24) × (5/23) = 25/1104

Therefore, the probability that Alan randomly selects a chocolate chip cookie from the bag, eats it, then randomly selects a peanut butter cookie is 25/1104.

Minimizing the sum of squared residuals.

How is the OLS estimator derived?

The OLS (Ordinary Least Squares) estimator is derived by minimizing the sum of squared residuals. This method aims to find the line of best fit that minimizes the vertical distance between the observed data points (Yi) and the predicted values on the regression line. The residuals represent the differences between the observed values and the predicted values.

By minimizing the sum of squared residuals, the OLS estimator ensures that the line fits the data as closely as possible. This approach is based on the principle of least squares, which seeks to find the parameters that minimize the overall discrepancy between the observed data and the predicted values.

Connecting the Yi corresponding to the lowest Xi observation with the Yi corresponding to the highest Xi or ensuring that the standard error of the regression equals the standard error of the slope estimator are not the steps involved in deriving the OLS estimator.

Answers

Answer is 15 meters


To solve this problem, we can use the formula for the perimeter of a rectangle, which is

P = 2l + 2w,

where P is the perimeter, l is the length, and w is the width.

We are given that Gabriella needs 120 meters of fence, which means that

P = 120.

We are also given that the length of the garden is three times its width, or

l = 3w.

Substituting these values into the formula, we get:

120 = 2(3w) + 2w

Simplifying this equation, we get:

120 = 8w

Dividing both sides by 8, we get:

w = 15

Answers

Answer:

To find the area of a triangle given its vertices, we can use the formula:

Area = 1/2 * |(x1*(y2-y3) + x2*(y3-y1) + x3*(y1-y2))|

where (x1,y1), (x2,y2), and (x3,y3) are the coordinates of the three vertices.

Using this formula, we can calculate the area of the triangle with vertices at (5,0), (-3,1), and (2,6) as follows:

Area = 1/2 * |(5*(1-6) + (-3)(6-0) + 2(0-1))|

= 1/2 * |-25 - 18 - 2|

c. How much area had the fire burned a week before it measured 4,800 acres, explain your reasoning

Answers

The fire had burned half the area (2,400 acres) one week before it measured 4,800 acres.

How to evaluate Days (d) and Burned area (y), the area burned in the fire, and the area the fire has burned a week before it measured 4,800 acres?

a. To complete the table, we substitute the values of d and evaluate the expression for y.

Days (d)      Burned area (y)

0                      0

1                      23,040

2                      92,160

3                      207,360

4                         368,640

b. When d = -1, the value of y = (4,800)^(2*(-1)) = (4,800)^(-2) = 3.255e-8. This value is very small, indicating that the burned area was negligible or not measurable at this point in time.

When d = -3, the value of y = (4,800)^(2*(-3)) = (4,800)^(-6) = 1.130e-34. This value is extremely small, indicating that there was essentially no burned area at this point in time.

c. To determine the number of days before the fire measured 4,800 acres, we need to solve the equation y = (4,800)^2 for d.

4,800^2 = (4,800)^2d

1 = 2dlog(4,800)

d = log(4,800) / (2log(4,800)) = 0.5

Therefore, the fire had burned half the area (2,400 acres) one week before it measured 4,800 acres. This is because the area burned increases quadratically with time, so the area burned one week before is the square root of the area measured at the time.

How to solve equation?

To solve an equation, you need to isolate the variable on one side of the equation, typically the left side, and simplify the other side until you are left with an expression that has only the variable you are trying to solve for.

Here are the general steps to solve an equation:

Start by simplifying both sides of the equation as much as possible. This may involve distributing or combining like terms.

Get all terms with the variable you are solving for on one side of the equation. To do this, you can add or subtract terms from both sides of the equation. For example, if you have the equation 2x + 5 = 9, you can subtract 5 from both sides to get 2x = 4.

Isolate the variable by dividing both sides of the equation by its coefficient. In the above example, you can divide both sides by 2 to get x = 2.

Check your solution by plugging it back into the original equation and verifying that both sides of the equation are equal.

Find the equation for h(t), and use it to determine how long it will take the plane to hit the ground. Round to the nearest hundredth

Answers

The paper airplane will not hit the ground within the given time frame.

To find the equation for h( t), we need to find the rate of change or the  pitch of the function. We can do this by chancing  the difference in height and time for any two points on the line. Let's choose the first two points,( 0,200) and( 1,208).  

pitch = ( change in height)/( change in time)  

pitch = ( 208- 200)/( 1- 0) =  8  

So, the equation for h( t) can be written in  pitch- intercept form as   h( t) =  8t b  

To find the value of b, we can use any of the given points.

Let's use( 0,200)   200 =  8( 0) b  b =  200  

So, the equation for h( t) is   h( t) =  8t 200  

To find how long it'll take the aeroplane to hit the ground, we need to find when h( t) =  0,

since that would mean the height is 0  bases or the ground  position.   0 =  8t 200   working for t,

What does the relationship between the mean and median reveal about the shape of the data? the mean is less than the median, so the data is skewed left. The mean is more than the median, so the data is skewed right. The mean is equal to the median, so the data is symmetrical. The mean is equal to the median, so the data is linear.

Answers

The mean is equal to the median, so the data is symmetrical.

Given that :

Colin surveyed 12 teachers at his school to determine how much each person budgets for lunch.

The data is :

10   5   8   10   12   6   8   10   15   6   12   18

Mean is the average of these numbers.

Mean = (10 + 5 + 8 + 10 + 12 + 6 + 8 + 10 + 15 + 6 + 12 + 18) / 12

         = 10

Now median is the element in the middle arranged in an order.

Arrange the data in ascending order.

5  6  6  8  8  10  10  10  12  12  15  18

The middle element is the average of the 6th and 7th elements.

Median = (10  10) / 2 = 10

So mean and the median is equal. So the data is symmetrical.

What value of k makes the equation true?



k – 3(k + 5) – 0. 5 = 3(0. 25k + 4)

Answers

For -10 as the value of k the equation k – 3(k + 5) – 0. 5 = 3(0. 25k + 4) is true.

Given equation is k – 3(k + 5) – 0. 5 = 3(0. 25k + 4)

To solve the equation, firstly we have to solve or open the brackets using the distributive property that is a(x + y) = ax +ay

Thus the equation becomes, k - 3k - 15 - 0.5 = 0.75k + 12

Then we have to take all the terms with k on one side and other on the other or segregate the like terms, the equation now is

k - 3k - 0.75k = 12 + 15 + 0.5

Simplify the equation by adding or subtracting the like terms.

-2.75k = 27.5

Then we divide the coefficient of k by the other side and get our answer

k = 27.5 ÷ (-2.75)

k = -10

If there are 30 people in a classroom, what is the probability that at least two have the same birthday

Answers

The probability that at least two people in a group of 30 have the same birthday is about 0.7063 or 70.63%.

To calculate the probability that at least two people in a group of 30 have the same birthday, we can use the complement rule:

P(at least 2 people have the same birthday) = 1 - P(all people have different birthdays)

The probability that the first person has a unique birthday is 1 (since there are no other people to share with yet).

The probability that the second person also has a unique birthday is 364/365 (since there are now 364 days left out of 365 that they could have a different birthday from the first person).

Similarly, the probability that the third person has a unique birthday is 363/365, and so on. So, we can write:

P(all people have different birthdays) = 1 x 364/365 x 363/365 x ... x 336/365

Using a calculator or computer program, we can evaluate this expression to be approximately 0.2937.

Therefore,

P(at least 2 people have the same birthday) = 1 - 0.2937 = 0.7063

So the probability that at least two people in a group of 30 have the same birthday is about 0.7063 or 70.63%.

Triangle ABC has vertices A(-1,1), B(1,3) and C(4,1). The image of ABC after the transformation matrix T=

Answers

The coordinates of transforming image of the vertices of the triangle ABC are A' (1, -1) ,B' (3, 1) , and C' (1, 4).

In triangle ABC,

Coordinates of the vertices of triangle ABC are,

A(-1,1), B(1,3) and C(4,1)

The transformation T y=x reflects the points across the line y=x.

The image of each point, we simply swap the x and y coordinates of each point.

So, applying the transformation T y=x to the vertices of triangle ABC, we get,

A' = (-1, 1) → (1, -1)

B' = (1, 3) → (3, 1)

C' = (4, 1) → (1, 4)

This implies,

The image of triangle ABC under the transformation T y=x is triangle A'B'C', where,

A' is located at (1, -1)

B' is located at (3, 1)

C' is located at (1, 4)

Therefore, in triangle ABC labeling the coordinates of the vertices of A'B'C'  after transformation are as follows,

A' (1, -1)

B' (3, 1)

C' (1, 4)

O is the centre of the given circle. if OX⊥PQ, OY⊥RS and PQ=RS, write down the relation between OX and OY.

Answers

Since OX is perpendicular to PQ, and OY is perpendicular to RS, we know that OX and OY are both radii of the circle. Therefore, we can write:

OX = OY

This is because all radii of a circle are equal in length. Alternatively, we could also say that OX and OY are both the distance from the center O to the respective lines PQ and RS. Since PQ=RS, OX and OY are equal in length.

What is the circle about?

In a circle, the center is the point from which all points on the circumference are equidistant. This means that any line segment from the center to a point on the circle is a radius of the circle.

In this problem, we have two lines PQ and RS, both of which are tangent to the circle at points P and R respectively. We also have two lines OX and OY, each of which is perpendicular to one of the tangent lines.

Because the tangent lines are perpendicular to their respective radii (PQ is perpendicular to OX, and RS is perpendicular to OY), we can conclude that OX and OY are both radii of the circle, and therefore, they have the same length.

Note that both are still angles at 90 degrees.

Answers

The expressions that could represent the length and width are (x - 2) units and (x - 7) units respectively.

To find the expressions that represent the length and width of the rectangle, we need to factor the given expression.

x² - 9x + 14 = (x - 2)(x - 7)

The length and width of the rectangle are represented by two factors of the expression.


To find the length and width of the rectangle, we need to understand the formula for the area of a rectangle, which is length multiplied by width. The given expression x²-9x+14 represents the area of the rectangle. To find the expressions that represent the length and width, we need to factor the given expression.

We can do this by finding two numbers that multiply to 14 and add up to -9. These numbers are -2 and -7. Therefore, we can factor the given expression as (x - 2)(x - 7). From this, we can see that the length of the rectangle is represented by the factor (x - 2) units and the width is represented by the factor (x - 7) units.

The second part of the new coaster is a parabola.

Ray needs help creating the second part of the coaster. Create a unique parabola in the pattern f(x) = (x − a)(x − b). Describe the direction of the parabola and determine the y-intercept and zeros.

Answers

The unique equation of the given parabola in the form of f(x) = (x - a)(x - b) is given by, f(x) = x(x + 6).

The y intercept of the parabola is at (0,0).

Zeros of the parabola are at x = 0, -6.

Given the model equation for the parabola is f(x) = (x - a)(x - b)

It is the standard equation of a parabola with zeros x = a, b.

Here from the graph we can see that at x = -6, 0 the value of y reaches 0 that is the parabola has zeros at x = 0, -6.

So, a = 0 and b = -6

So, f(x) = (x - 0)(x - (-6))

f(x) = x(x + 6)

From the graph we can also see that the parabola is downward negative Y axis.

At y intercepts x = 0

So, the equation becomes in that case,

f(x) = 0.

So (0, 0) is the only y intercept of the parabola.

Hence, the equation of the unique parabola is, f(x) = x(x + 6) and Y intercept is at (0, 0) and zeros are at x = 0, -6.
