5. A baseball is hit by a batter. The following function describes the height of the baseball as a function of time (t seconds after the ball was struck):
h--16t^2 + 48+ 2
How many seconds after the ball was struck did it reach a maximum height?
a. 1 sec
b. 1.5 sec
o. 2 sec
d. 2.5 sec
Need help ASAP please

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
