TSIA2 Math Practice Test #1

Front

What is the formula for the area of a square?

Back

The area of a square is given by the formula: Area = side^2.

Front

If the area of a square is 100, what is the length of one side?

Back

The length of one side is 10, since side = sqrt(Area) = sqrt(100) = 10.

Front

What is a y-intercept in a function?

Back

The y-intercept is the point where the graph of a function intersects the y-axis, represented as (0, f(0)).

Front

Back

To find the y-intercept, substitute x=0 into the function: f(0) = (0-3)(0-1)+4 = 7, so the y-intercept is (0, 7).

Front

What are factors in algebra?

Back

Factors are numbers or expressions that can be multiplied together to get another number or expression.

Front

What is the perimeter of an equilateral triangle?

Back

The perimeter of an equilateral triangle is the sum of the lengths of all three sides, which are equal.

Front

If an equilateral triangle has a perimeter of 24 feet, what is the length of one side?

Back

The length of one side is 8 feet, since side = Perimeter/3 = 24/3 = 8.

Front

What is the formula for the area of a square?

Back

Area = side^2.

Front

If one side of a square is 8 feet, what is the area?

Back

The area is 64 square feet, since Area = 8^2 = 64.
