When a baseball is hit by a batter, the height of the ball, h(t), at time t, t=0 is determined by the equation h(t)=-16t^2+64t^2+4. if t is in seconds, for which interval of time is the height of the ball greater than or equal to 52 feet?
a: 1 b: t< =1
c: 0 d: 1< =t< =3

Let

t--------> the time in seconds

h--------> the height of the ball in feet

we know that

Using a graphing tool

see the attached figure

The height of the ball is greater than or equal to feet for

therefore

the answer is the option D

step-by-step explanation:

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20
