Answers
Answer:
Z = 22.5, Y = 81, X = 26.7
Step-by-step explanation:
Using the lengths you do know compare them to the copy, the only two lengths available that are for the same side length are 33 and 22, divide them together and you get 1.5. Thats the scale factor. Everything else you can figure out by multiplying or dividing by this scale factor.
\(Z = (15)(1.5) = 22.5\\Y = (54)(1.5) = 81\\X = (40)/(1.5) = 26.7\)

The average rate of change between t = 0 and t = 2 is 16 feet/second and the average rate of change between t = 1 and t = 2 is 8 feet/second.
The correct answer choice is option A and C respectively.
What is the average rate of change?The average rate of change between t = 0 and t = 2
At t = 0
h(t) = -16t² + 40t + 6
= -16(0)² + 40(0) + 6
= 0 + 0 + 6
= 6 feet/second
At t = 2
h(t) = -16t² + 40t + 6
= -16(2)² + 40(2) + 6
= -16(4) + 80 + 6
= -64 + 80 + 6
= 22 feet/second
The average rate of change between t = 0 and t = 2 is
22 feet - 6 feet
= 16 feet/second
At t = 1
h(t) = -16t² + 40t + 6
= -16(1)² + 40(1) + 6
= -16 + 40 + 6
= 30 feet/second
Therefore,
The average rate of change between t = 1 and t = 2 is
30 feet - 22 feet
= 8 feet

Quit smoking: In a survey of 444 HIV-positive smokers, 202 reported that they had used a nicotine patch to try to quit smoking. Can you conclude that less than half of HIV-positive smokers have used a nicotine patch
Answers
Answer:
The p-value of the test is of 0.0287 < 0.05(standard significance level), which means that it can be concluded that less than half of HIV-positive smokers have used a nicotine patch.
Step-by-step explanation:
Test if less than half of HIV-positive smokers have used a nicotine patch:
At the null hypothesis, we test if the proportion is of at least half, that is:
\(H_0: p \geq 0.5\)
At the alternative hypothesis, we test if the proportion is below 0.5, that is:
\(H_1: p < 0.5\)
The test statistic is:
\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)
In which X is the sample mean, \(\mu\) is the value tested at the null hypothesis, \(\sigma\) is the standard deviation and n is the size of the sample.
0.5 is tested at the null hypothesis:
This means that \(\mu = 0.5, \sigma = \sqrt{0.5*(1-0.5)} = 0.5\)
In a survey of 444 HIV-positive smokers, 202 reported that they had used a nicotine patch to try to quit smoking.
This means that \(n = 444, X = \frac{202}{444} = 0.455\)
Value of the test statistic:
\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)
\(z = \frac{0.455 - 0.5}{\frac{0.5}{\sqrt{444}}}\)
\(z = -1.9\)
P-value of the test and decision:
The p-value of the test is the probability of finding a sample proportion below 0.455, which is the p-value of z = -1.9.
Looking at the z-table, z = -1.9 has a p-value of 0.0287.
The p-value is of 0.0287 < 0.05(standard significance level), which means that it can be concluded that less than half of HIV-positive smokers have used a nicotine patch.

Answers
Answer:
-72x - 53y + 287 = 0.
Step-by-step explanation:
To find the equation of the image of the circle, we need to reflect each point on the circle in the given line mirror.
The line mirror equation is given as 4x + 7y + 13 = 0.
The reflection of a point (x, y) in the line mirror can be found using the formula:
x' = (x - 2Ay - 2B(Ax + By + C)) / (A^2 + B^2)
y' = (y - 2Bx + 2A(Ax + By + C)) / (A^2 + B^2)
where A, B, and C are the coefficients of the line mirror equation.
For the given line mirror equation 4x + 7y + 13 = 0, we have A = 4, B = 7, and C = 13.
Now, let's find the equations of the image of the circle.
The original circle equation is x² + y² + 16x - 24y + 183 = 0.
Using the reflection formulas, we substitute the values of x and y in the circle equation to find x' and y':
x' = (x - 2Ay - 2B(Ax + By + C)) / (A^2 + B^2)
= (x - 2(4)y - 2(7)(4x + 7y + 13)) / (4^2 + 7^2)
= (x - 8y - 8(4x + 7y + 13)) / 65
= (x - 8y - 32x - 56y - 104) / 65
= (-31x - 64y - 104) / 65
y' = (y - 2Bx + 2A(Ax + By + C)) / (A^2 + B^2)
= (y - 2(7)x + 2(4)(Ax + By + C)) / (4^2 + 7^2)
= (y - 14x + 8(Ax + By + C)) / 65
= (y - 14x + 8(4x + 7y + 13)) / 65
= (57x + 35y + 104) / 65
Therefore, the equation of the image of the circle is:
(-31x - 64y - 104) / 65 + (-57x + 35y + 104) / 65 + 16x - 24y + 183 = 0
Simplifying the equation, we get:
-31x - 64y - 57x + 35y + 16x - 24y + 183 + 104 = 0
-72x - 53y + 287 = 0
So, the equation of the image of the circle is -72x - 53y + 287 = 0.

To calculate the volume of this prism, we just have to calculate the area of the trapezoidal face and multiply by the length of the prism.
In another words, multiply the area of the blue trapezoid by the green length.
The area of a trapezoid is given by half the sum of the basis times the height
\(A=\frac{(B+b)h}{2}\)The bigger base of our trapezoid measures 6 yd, the smaller base measures 2 yd, and the height measures 3.5 yd. Using those values in our formula, we have:
\(A=\frac{(6+2)\times3.5}{2}=14\)Then, multiplying by the green length, we have the volume:
\(V=A\times6=14\times6=84\)The volume of this prism is 84 yd³. The answer is option D.

Exercise 1.2
A person has G¢60 to spend on two goods, X and Y, whose respective prices are GH¢6 and GH¢4.
(a) Draw a budget line showing all the different combinations of the two goods that can be bought within the given budget.
(b) What happens to the original budget line if the budget is increased by 20%?
(c) What happens to the original budget line if the price of X is halved?
Answers
(a) The maximum combination of X and Y is (10, 15).
(b). The new maximum combination of X and Y is (12, 18).
(c). The new maximum combination of X and Y is (20, 15).
To draw the budget line, we need to determine the different combinations of goods X and Y that can be bought within the given budget.
The budget line represents all the possible combinations of X and Y that can be purchased with G¢60.
Let's assume the quantity of good X is represented on the x-axis and the quantity of good Y is represented on the y-axis.
The combinations, we can start with the maximum quantity of each good that can be purchased with the given budget.
Given that the price of X is GH¢6 and the price of Y is GH¢4, we can calculate:
Maximum quantity of X = G¢60 / GH¢6 = 10
Maximum quantity of Y = G¢60 / GH¢4 = 15
Now, we can plot the budget line connecting this point with the origin (0, 0).
The budget line represents all the combinations of X and Y that can be purchased with G¢60.

(b) If the budget is increased by 20%, the new budget will be 120% of the original budget.
New budget = 120% of G¢60 = 1.2 × G¢60
= G¢72
To draw the new budget line, we repeat the steps from part (a) using the new budget of G¢72.
Maximum quantity of X = G¢72 / GH¢6 = 12
Maximum quantity of Y = G¢72 / GH¢4 = 18
Plotting the new budget line:

(c) If the price of X is halved, the new price of X will be GH¢6 / 2 = GH¢3.
To draw the new budget line, we keep the budget and the price of Y the same as in the original scenario.
Only the price of X changes.
Maximum quantity of X = G¢60 / GH¢3 = 20
Maximum quantity of Y = G¢60 / GH¢4 = 15
Plotting the new budget line:

Complete the table of values for the equation 4x + 2y =64
Answers
The completed table of values for the equation 4x + 2y = 64 is provided .
To complete the table of values for the equation 4x + 2y = 64, we can assign different values to x and solve for y. Let's choose a range of values for x and calculate the corresponding values of y.
Table of Values:
x y

4 28
8 24
12 20
16 16
20 12

28 4
32 0
To find the values of y, we substitute each x-value into the equation and solve for y. For example, when x is 0, we have 4(0) + 2y = 64, which simplifies to 2y = 64 and y = 32. Similarly, for x = 4, we have \(4(4) + 2y = 64\), which simplifies to \(16 + 2y = 64\) and\(y = 28.\)
By continuing this process for the remaining values of x, we can complete the table of values for the equation 4\(x + 2y = 64.\)

In one minute caterpillar crawls 25 inches. So in 5 minutes we have 5 times 25 inches is 125 inches.
By equation
Additional: 25 + 25 + 25 + 25 + 25 = 125 (inches)
Mutiplication: 25 * 5 = 125 (inches)
The caterpillar crawls 125 inches in 5 minutes
because it is said that the caterpillar crawls 25 inches in one minute so we can use multiplication 25 x 5 = 125
