# Is This Math Test Insanely Hard Or Not?

Algebra...more like algehuh?

1. ## In the following expression, what is the coefficient?

Correct!
Wrong!

"4"

A coefficient is a number or quantity placed (generally) before, and multiplying, another quantity.

2. Which of the following equations would you use to find the area of a square?

Getty/yustoprst
Correct!
Wrong!

A = s2

The area of a square is given by the formula "area = width Ã— height." But since the width and height are by definition the same, the formula is usually written as A = s2.

3. ## In the triangle below, what is the sine of angle A?

Correct!
Wrong!

.5

To find the sine of an angle, divide the length of the opposite line by hypotenuse. In this case, sin(A) = 5/10 or .5.

4. Correct!
Wrong!

The logarithm of 8 with base 2 is 3.

5. In the equation
y=m(x)+b,
what does the "m" represent?

Getty/yustoprst
Correct!
Wrong!

The slope of a line

"m" represents the slope of the line, while "b" represents the y-intercept.

6. ## How would you label the section of the circle pointed to below?

Correct!
Wrong!

The area pointed to is an arc with endpoints A and C.

7. A triangle with three unequal sides is known as:

Correct!
Wrong!

A scalene triangle

A scalene triangle has 3 unequal sides. An isosceles triangle has at least 2 equal sides. An equilateral triangle has 3 equal sides. And a radial triangle is not a thing...I made it up.

8. ## In the following function, what is the domain of "h"?

Correct!
Wrong!

All real values of x.

The domain is the set of all possible x-values that will make the function "work," and will output real y-values.

9. Which of the following equations would you use to find the distance between two points on a coordinate plane?

Getty/yustoprst
Correct!
Wrong!

To find the distance between two points on a coordinate plane, use a formula that is based on the Pythagorean theorem where (x1, y1) and (x2, y2) are the coordinates and d marks the distance.

10. ## How would you factor the following expression?

Correct!
Wrong!

(x+1)(x+3)

Factoring is the process of finding what to multiply together to get an expression.
