NC Math 1 EOC Review

Front

What is the formula for the height of an object launched upward?

Back

s(t) = -16t² + vt + h, where v is the initial velocity and h is the initial height.

Front

How do you find the maximum height of a projectile?

Back

Use the vertex formula t = -b/(2a) in the equation s(t) = at² + bt + c.

Front

What is the maximum height of an object launched at 64 ft/s from 80 ft high?

Back

144 ft.

Front

What does the variable 't' represent in the height equation s(t) = -16t² + 64t + 80?

Back

Time in seconds.

Front

What is the significance of the coefficients in the quadratic equation s(t) = -16t² + 64t + 80?

Back

-16 is the acceleration due to gravity (in ft/s²), 64 is the initial velocity, and 80 is the initial height.

Front

What is an inequality?

Back

A mathematical statement that indicates one quantity is less than or greater than another.

Front

What is the vertex of a parabola in the context of a quadratic function?
