To solve for t using the quadratic formula, what expressions for a, b and c should be used?

Step-by-step explanation:

The given formula for the height of the projectile is

This is a quadratic equation in .

To solve for t, we set the equation to zero to get;

where is the coefficient of , is the coefficient of , and is the constant term.

The correct answer is C

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
