NC Math 2 Final Exam Review

Front

What is the formula for the height of an object thrown into the air?

Back

The height, h, in feet after t seconds is given by the function f(t) = -16t² + vt + h₀, where v is the initial velocity and h₀ is the initial height.

Front

How do you determine the time it takes for a projectile to return to the ground?

Back

Set the height function equal to zero and solve for t.

Front

What is a proportion in mathematics?

Back

A proportion is an equation that states that two ratios are equal.

Front

If AB / BM = AC / CD, what does AC represent?

Back

AC represents the length of the segment that completes the proportion.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

How do you find the measure of a missing angle in a triangle?

Back

Subtract the sum of the known angles from 180 degrees.

Front

What is the vertex of a quadratic function?

Back

The vertex is the highest or lowest point of the parabola represented by the quadratic function.

Front

How do you find the vertex of the function y = ax² + bx + c?

Back

The vertex can be found using the formula (-b/(2a), f(-b/(2a))).

Front

What does the term 'initial velocity' mean in projectile motion?

Back

Initial velocity is the speed at which an object is thrown or launched at the beginning of its motion.

Front

What is the significance of the coefficient of t² in the height function?

Back

The coefficient of t² indicates the acceleration due to gravity, which is negative in projectile motion.
