Aball is thrown from a height of 160 feet with an initial downward velocity of 12 ft/s.
. the ball's height h (in feet) after t seconds is given by the following.
h= 160 - 12t - 16t^2

how long after the ball is thrown does it hit the ground?
round your answer(s) to the nearest hundredth.

Step-by-step explanation:

Solve the quadratic equations for h = 0

Quadratic formula:

(12 +- sqrt(144-4(-16)(160)))/32

(12 +- sqrt(10384))/32

t= -2.81 (disregard this because a negative doesn't make since in this context)

t=3.56

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
