The image coordinates of N′M′O′ if the preimage is translated 7 units to the left is D- N′(−11, −2), M′(−8, −1), O′ (−11, −5)

What is image coordinates?

A triangle is seen as a closed, two-dimensional geometric figure that has three straight sides and three angles.

To get the image coordinates of the preimage translated 7 units to the left, we simply subtract 7 from the x-coordinates of each vertex:

N' = (Nx - 7, Ny) = (−4 - 7, −2) = (−11, −2)

M' = (Mx - 7, My) = (−1 - 7, −1) = (−8, −1)

O' = (Ox - 7, Oy) = (−4 - 7, −5) = (−11, −5)

Therefore, the image coordinates of NMO after the translation 7 are: N′(−11, −2), M′(−8, −1), O′ (−11, −5)

ķojo and kofta were given 38000 to share. kojo had 7500 more than kofta find each of their shares Show working​

Answers

Answer:

Kofta receives $15,250 and Kojo receives $22,750.

Step-by-step explanation:

Let x represent the amount of money that Kofta has.

x + (x +7,500) = 38,000

          - 7,500   - 7,500

___________________

x + x = 30,500

2x = 30,500

÷ 2 = ÷2

-------------------

x = 15,250

Therefore, Kofta has $15,250.

Let k represent the amount of money that Kojo has.

k + 15,250 = 38,00

k = 38,000 - 15,250

k =  $22,750

Therefore, Kojo has $22,750

The base and all three faces of a triangle pyramid are equilateral triangles with side lengths of 3ft. the height of each triangle is 2.6ft. what are the lateral area and the total surface area of the triangular pyramid?

Answers

The lateral area of the triangular pyramid is 11.7 sq ft and the total surface area is 15.6 sq ft.

To find the lateral area and total surface area of the triangular pyramid with base and faces as equilateral triangles, we can follow these steps:

1: Find the area of one equilateral triangle.

To find the area of an equilateral triangle with side length 3 ft and height 2.6 ft, we can use the formula:

Area = (1/2) × base × height

Area = (1/2) × 3 × 2.6 = 3.9 sq ft

2: Calculate the lateral area.

Since the pyramid has three equilateral triangles as faces, we can multiply the area of one triangle by 3 to find the lateral area:

Lateral Area = 3 × 3.9 = 11.7 sq ft

3: Calculate the total surface area.

The total surface area includes both the lateral area and the base area. Since the base is also an equilateral triangle with the same dimensions, we can simply add the area of the base to the lateral area to find the total surface area:

Total Surface Area = Lateral Area + Base Area = 11.7 + 3.9 = 15.6 sq ft

In conclusion, the lateral area is 11.7 sq ft and the total surface area is 15.6 sq ft.

The rate of change of the gender ratio for the United States during the twentieth century can be modeled as g(t) = (1. 68 · 10^−4)t^2 − 0. 02t − 0. 10


where output is measured in males/100 females per year and t is the number of years since 1900. In 1970, the gender ratio was 94. 8 males per 100 females.



(a) Write a specific antiderivative giving the gender ratio.


G(t) = _______________ males/100 females



(b) How is this specific antiderivative related to an accumulation function of g?


The specific antiderivative in part (a) is the formula for the accumulation function of g passing through (t, g) =

Answers

Answer:

(a) G(t) = (1.68 × 10^-4) × (1/3) t^3 - (0.02/2) t^2 - 0.10t - 2445.84

(b) A(t) = G(t) - G(1900) = (1.68 × 10^-4) × (1/3) (t^3 - 1900^3) - (0.02/2) (t^2 -     1900^2) - 0.10(t - 1900)

Step-by-step explanation:

(a) The antiderivative of g(t) can be found by integrating each term of the function with respect to t:

∫g(t) dt = ∫(1.68 × 10^-4)t^2 dt - ∫0.02t dt - ∫0.10 dt

= (1.68 × 10^-4) × (1/3) t^3 - (0.02/2) t^2 - 0.10t + C

where C is the constant of integration.

To find the specific antiderivative G(t) that passes through the point (1970, 94.8), we can use this point to solve for C:

94.8 = (1.68 × 10^-4) × (1/3) (1970)^3 - (0.02/2) (1970)^2 - 0.10(1970) + C

C = 94.8 + (1.68 × 10^-4) × (1/3) (1970)^3 - (0.02/2) (1970)^2 - 0.10(1970)

C ≈ -2445.84

Therefore, the specific antiderivative that gives the gender ratio is:

G(t) = (1.68 × 10^-4) × (1/3) t^3 - (0.02/2) t^2 - 0.10t - 2445.84

(b) The accumulation function of g is the integral of g with respect to t, or:

A(t) = ∫g(t) dt = G(t) + C

where C is the constant of integration. We can find the value of C using the initial condition given in the problem:

A(1900) = ∫g(t) dt ∣t=1900 = G(1900) + C = 0

Therefore, C = -G(1900), and the accumulation function of g is:

A(t) = G(t) - G(1900) = (1.68 × 10^-4) × (1/3) (t^3 - 1900^3) - (0.02/2) (t^2 - 1900^2) - 0.10(t - 1900)

Evaluate the following expression. Your answer must be in exact form: for example, type pi/6 for π/6 or DNE if the expression is undefined. arcsin (sin (-57π/10))=

Answers

For the following expression arcsin (sin (-57π/10)) is 3π/10.

The function arcsin(x) gives the angle in radians whose sine is x.

In this problem, we need to find the angle whose sine is equal to the sine of -57π/10.

First, we need to simplify -57π/10 to an angle in the range [-π/2, π/2] since the sine function has a range of [-1, 1]. To do this, we use the fact that sine has a period of 2π,

which means that sin(-57π/10) = sin((-57π/10) + 4π) = sin(3π/10).

So we need to find the angle θ such that sin(θ) = sin(3π/10).

Since sine is an odd function, we know that sin(-θ) = -sin(θ), so we can also say that sin(θ) = sin(-3π/10).

Therefore, there are two possible angles that satisfy the equation: θ = 3π/10 or θ = -3π/10.

However, since the range of the arcsine function is [-π/2, π/2], only the angle in that range that satisfies the equation is θ = 3π/10.

Therefore, we can write:

arcsin(sin(-57π/10)) = arcsin(sin(3π/10)) = 3π/10

The answer is 3π/10.

let f be the function defined above. what is the integral of f(x) from -1 to 1

Answers

The value of given function [tex]\int\limits^1_{-1}[/tex]f(x)dx is equal is 5/6. So, correct option is A.

To find the integral of f(x) from -1 to 1, we need to split the interval [-1,1] into three parts, where f(x) is defined differently.

For x < 0, f(x) = x², so the integral of f(x) from -1 to 0 is:

[tex]\int\limits^0_{-1}[/tex](x²)dx = (-1/3)x³ evaluated at x=0 and x=-1 = (-1/3)(0 - (-1)) = 1/3

For x = 0, f(x) = -1, so the integral of f(x) at x=0 is simply -1.

For x > 0, f(x) = x, so the integral of f(x) from 0 to 1 is:

[tex]\int\limits^1_{0}[/tex](x)dx = (1/2)x² evaluated at x=1 and x=0 = (1/2)(1 - 0)² = 1/2

Therefore, the integral of f(x) from -1 to 1 is:

[tex]\int\limits^1_{-1}[/tex]f(x)dx = [tex]\int\limits^0_{-1}[/tex](x²)dx  + [tex]\int\limits^0_{0}[/tex](-1)dx + [tex]\int\limits^1_{0}[/tex](x)dx

= 1/3 + (-1) + 1/2

Thus, the correct answer is (a) 5/6.

The ratio of dolls thta jack had to peter was 5:2. After jack gave peter 15 dolls, they had the same amount of dolls. How many do they have together?

Answers

They have total of 70 dolls together.

Let the initial number of dolls Jack had be 5x and the number Peter had be 2x.


After Jack gave Peter 15 dolls, their amounts became equal. So, we can write the equation: 5x - 15 = 2x + 15

Now, solve the equation for x: 5x - 2x = 15 + 15, which simplifies to 3x = 30

Divide both sides by 3: x = 10

Now, find the initial number of dolls they had: Jack had 5x = 5(10) = 50 dolls, and Peter had 2x = 2(10) = 20 dolls.

After Jack gave Peter 15 dolls, both had 35 dolls (50 - 15 = 35, and 20 + 15 = 35).

Rascoville is a large city with a population of 3 million people. What is the average ozone level? __________________________



If the ozone level is approximately 142 ppm, what is the approximate population in millions (round to the nearest million)? __________________________________

Answers

Interpretation:

The regression coefficient b = 16.6 represents the change in the predicted ozone level (in parts per million) for each additional million people in the population.

Specifically, for each additional million people, the predicted ozone level is expected to increase by 16.6 parts per million.

For Rascoville, a city with a population of 3 million people, we can use the estimated regression equation to predict the average ozone level:

ozone⌢ = 8.89 + 16.6 × 3 = 8.89 + 49.8 = 58.69

Therefore, the predicted average ozone level for Rascoville is 58.69 parts per million.

If the ozone level is approximately 142 ppm, we can use the estimated regression equation to estimate the population:

142 = 8.89 + 16.6 × population

Solving for population, we get:

133.11 = 16.6 × population

population ≈ 8.02 million

Therefore, the approximate population of the city is 8 million people (rounded to the nearest million).

A) 2903 meters


B) 3263 meters C) 1329 meters D) 1997 meters

Answers

The distance between the factories is approximately 1704 meters.

To solve this problem, we can use the Law of Cosines. Let's denote the distance between the man and Factory 1 as x, the distance between the man and Factory 2 as y, and the distance between the factories as z.

Given that the time difference for the man to hear the blasts from Factory 1 and Factory 2 is 4.2 seconds and 5.9 seconds respectively, we can calculate x and y using the speed of sound (344 m/s):

x = 4.2 seconds * 344 m/s = 1444.8 meters
y = 5.9 seconds * 344 m/s = 2030.4 meters

Now, we apply the Law of Cosines using the given angle of 40.8°:

z² = x² + y² - 2xy * cos(40.8°)
z² = 1444.8² + 2030.4² - 2(1444.8)(2030.4) * cos(40.8°)
z² ≈ 2904106.33

Take the square root to find the distance between the factories:

z ≈ √2904106.33 ≈ 1704.14 meters

Need answer ASAP Please!!

Answers

Answer:

[tex]x^2+\left(y+\dfrac{1}{2}\right)^2=\dfrac{49}{4}[/tex]

Step-by-step explanation:

The center of the circle is the midpoint of its diameter.

[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Midpoint between two points}\\\\Midpoint $=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)$\\\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the endpoints.\\\end{minipage}}[/tex]

Given the endpoints of the diameter are (0, 3) and (0, -4), to find the coordinates of the center of the circle, substitute the two endpoints into the midpoint formula:

[tex]\text{Center}=\left(\dfrac{0+0}{2},\dfrac{-4+3}{2}\right)=\left(0,-\dfrac{1}{2}\right)[/tex]

As the x-values of the endpoints of the diameter are the same, the length of the diameter, d, is the absolute value of the difference in y-values of the endpoints:

[tex]d=|3-(-4)|=7[/tex]

Therefore, the diameter of circle Q is 7 units.

The radius, r, of a circle is half its diameter. Therefore:

[tex]r=\dfrac{d}{2}=\dfrac{7}{2}[/tex]

[tex]\boxed{\begin{minipage}{4 cm}\underline{Equation of a circle}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h,k)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]

Now we have determined the center and radius of circle Q, we can substitute these values into the equation of a circle to write the equation of circle Q in standard form:

[tex](x-0)^2+\left(y-\left(-\dfrac{1}{2}\right)\right)^2=\left(\dfrac{7}{2}\right)^2[/tex]

[tex]x^2+\left(y+\dfrac{1}{2}\right)^2=\dfrac{49}{4}[/tex]

Therefore, the equation of circle Q in standard form is:

Interpretation:

Answers

The margin of error at the 99% confidence interval is 0.018 or 1.8%.

Interpretation: This means that if we were to repeat the survey many times, about 99% of the intervals calculated from the samples would contain the true proportion of viewers under 30 in the population, and the margin of error for each interval would be no more than 1.8%.

The margin of error is the amount by which the sample statistic (in this case, the proportion of viewers under 30) may differ from the true population parameter.

Using the given formula for margin of error:

Margin of error = z* * sqrt(p*(1-p)/n)

Where:

- z* is the z-score corresponding to the confidence level (99% in this case), which is 2.576

- p is the proportion of viewers under 30, which is 0.3

- n is the sample size, which is 5000

Substituting these values, we get:

Margin of error = 2.576 * sqrt(0.3*(1-0.3)/5000) = 0.018

In what time will Rs. 6350 amounts to Rs. 8255 if the simple Interest is calculated at 10% per annum ?Also, find the rate of interst if He returns in 1 1/2 years .

Answers

Therefore, it will take 3 years for Rs. 6350 to amount to Rs. 8255 at 10% per annum. Therefore, the rate of interest is 32.6% per annum if the loan is returned in 1 1/2 years.

What is interest?

Interest is the amount of money that a lender charges a borrower for the use of money or assets. It is typically expressed as a percentage of the amount borrowed or invested, and is paid by the borrower to the lender as compensation for the use of the money. There are two main types of interest: simple interest and compound interest. Simple interest is calculated based on the initial amount borrowed or invested, and is paid out at regular intervals over a fixed period of time. Compound interest, on the other hand, is calculated based on the initial amount plus any accumulated interest, and is paid out at the end of the investment period.

Here,

Using the formula for simple interest:

Simple Interest = (Principal x Rate x Time) / 100

where Principal is the initial amount, Rate is the interest rate per annum, and Time is the duration of the loan in years. To find the time it takes for Rs. 6350 to amount to Rs. 8255 at 10% per annum, we can set up the equation:

8255 - 6350 = (6350 x 10 x Time) / 100

Simplifying the equation, we get:

1905 = 635 x Time

Time = 1905 / 635

Time = 3 years

To find the interest rate if the loan is returned in 1 1/2 years, we can rearrange the formula for simple interest as:

Rate = (100 x Simple Interest) / (Principal x Time)

Plugging in the values, we get:

Rate = (100 x (8255 - 6350)) / (6350 x 1.5)

Rate = 3105 / 9525

Rate = 0.326 or 32.6%

Find the gradients of the lines a and b

Answers

The gradient of line A and B are 4 and - 2 respectively.

How to find the gradient or slope of a line?

The gradient or slope of a line is a the change in the dependent variable with respect to the change in the independent variable.

Therefore, let's find the gradient of line a and b as follows:

(2, -1)(3, 3)

Gradient  of line A = 3 + 1 / 3 - 2

Gradient  of line A = 4 / 1

Gradient  of line A = 4

Examine this system of equations. What integer should the first equation be multiplied by so that when the two equations are added together, the x term is eliminated?

StartFraction 1 Over 18 EndFraction + four-fifths y = 10

Negative five-sixths x minus three-fourths y = 3

Answers

Answer:

To solve this problem, we need to find an integer to multiply the first equation by so that when we add the two equations together, the x term is eliminated. Let's first rearrange the equations to make them easier to work with:

1/18 x + 4/5 y = 10

-5/6 x - 3/4 y = 3

To eliminate the x term, we need to multiply the first equation by a certain integer so that when we add it to the second equation, the x terms cancel out. To do this, we need to find a common multiple of the denominators of the x coefficients in both equations, which are 18 and -6. The least common multiple of 18 and -6 is 18, so we can multiply the first equation by 18:

18(1/18 x + 4/5 y = 10)

Simplifying this equation, we get:

x + 72/5 y = 180

Now we can add this equation to the second equation:

x + 72/5 y = 180

-5/6 x - 3/4 y = 3

Multiplying the second equation by 15 to get rid of the fractions, we get:

-25/2 x - 45/4 y = 45

Now we can add the two equations together to eliminate the x term:

-25/2 x + x + 72/5 y - 45/4 y = 180 + 45

Simplifying this equation, we get:

-13/20 y = 225/4

Multiplying both sides by -20/13, we get:

y = -450/13

Therefore, the integer we need to multiply the first equation by is 18, which corresponds to option B.

How could you use a set of coin flips to simulate this situation?

Answers

Answer:

Let heads represent a person who exercises the given amount, and let tails represent a person who doesn’t. Because there are three people, flip the coin three times (once for each person) and note the results of each set of three flips. If all three flips land on tails, it would mean that all three randomly selected people do not exercise as much as 50% of Americans do.

What is sine rule?

The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.

The measure of angle R = 180-( 48+29)

R = 180- 77

R = 103°

sinR/ r = sinS/s

sin103 / 58 = sin48/s

s × sin103 = 58 × sin48

s × 0.974 = 43.1

s = 43.1/0.974

s = 44.3 cm
