Question

The height of another frog over time is modeled by the function y= -16t^2 + 10t +0.3. How many seconds is this frog in the air before landing on the ground? Round your answer to the nearest hundredth.

please answer quickly

Answer 1

Explanation:

y will equal 0 when the frog hits on the ground after being in the air:

0 = -16t^2 + 10 t + 0.3

Use quadratic formula with a = -16 b = 10 c = 0.3

to find t = .65 seconds
