## Answers:

1- **B**

\(tanθ=\frac{opposite}{adjacent}\)

\(tanθ=\frac{5}{12}\)⇒ we have the following right triangle. Then

\(c=√(5^2+12^2 )=√(25+144)=√169=13\)

\(\frac{adjacent}{hypotenuse}=\frac{12}{13}\)

2- **E**

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

3-** 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.

4- **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 \((-10,3)\).

5- **B**

The area of trapezoid is:

\((\frac{8+12}{2})×x=100→10x=100→x=10\)

\(y=√(3^2+4^2 )=5\)

\(Perimeter \space is: 12+10+8+5=35\)

6- **E**

\(g(x)=-2, then f(g(x))= f(-2)=2 (-2)^3+5(-2)^2+2(-2)= -16+20-4=0\)

7- **B**

\(x = \frac{8y + \frac{r}{r + 1}}{\frac{6}{\frac{z}{3}}}\)

\(x = \frac{8y + \frac{r}{r + 1}}{\frac{3×6}{z}}\)

\(\frac{1}{3}×\frac{8y +\frac{r}{r + 1}}{\frac{6}{z}}=\frac{x}{3}\)

8- **B**

Use the information provided in the question to draw the shape.

Use Pythagorean Theorem: \(a^2 + b^2 = c^2\)

\(402 + 302 = c2 ⇒ 1600 + 900 = c2 ⇒ 2500 = c2 ⇒ c = 50\)

9- **A**

Let the number be \(A\). Then:

\(x=y\% ×A\)

Solve for \(A\).

\(x = \frac{y}{100}×A\)

Multiply both sides by \(100/y\):

\(x×\frac{100}{y}=\frac{y}{100}×\frac{100}{y}×A\)

\(A=\frac{100x}{y}\)

10- **C**

\(tangent β=\frac{1}{cotangent β}=1\)
