## Answers:

1- **D**

The amplitude in the graph of the equation \(y=a\)cos\(bx\) is a. (\(a\) and \(b\) are constant)

In the equation \(y=\)cos\(x\), the amplitude is 2 and the period of the graph is \(2π\).

The only option that has two times the amplitude of graph \(y = \)cos \(x\) is \(y=2+2\) cos \(x\)

They both have the amplitude of 2 and period of \(2π\).

2- **B**

\(\frac{2}{3}≅0.67,\frac{8}{11}≅0.73,\frac{5}{7}≅0.71,\frac{3}{4}=0.75\)

3-** B**

ratio of A: \(\frac{570}{600}=0.95\)

ratio of B: \(\frac{291}{300}=0.97\)

ratio of C: \(\frac{665}{0.95}=0.95\)

ratio of D: \(\frac{528}{550} =0.96\)

4- **E**

First find percentage of men in city A and percentage of women in city C.

Percentage of men in city A =\(\frac{600}{1170}\) and percentage of women in city C =\(\frac{665}{1365}\)

Find the ratio and simplify.

\(\frac{\frac{600}{1170}}{\frac{665}{1365}}=\frac{20}{19}\)

5- **C**

\(\frac{528+x}{550}==1.2→528+x=660→x=132\)

6- **A**

Let \(x\) be the number of years. Therefore, $2,000 per year equals 2000\(x\).

starting from $24,000 annual salary means you should add that amount to 2000\(x\).

Income more than that is:

\(I > 2000 x + 24000\)

7- **B**

We write the numbers in the order: \(1, 1, 1, 2, 2, 3, 3, 3, 4, 4, 5\)

The mode of numbers is: 1 and 3, median is: 3

8- **E**

\(0.6x=(0.3)×20→x=10→(x+5)^2=(15)^2=225\)

9- **E**

The slop of line A is: m\(= \frac{y_2-y_1}{x_2-x_1}=\frac{3-2}{4-3}=1\)

Parallel lines have the same slope and only choice E \((y=x)\) has slope of 1.

10- **C**

When points are reflected over \(y\)-axis, the value of \(y\) in the coordinates doesn’t change and the sign of \(x\) changes. Therefore, the coordinates of point B is \((-10,3)\).
