Tim throws a stick straight up in the air from the ground. the function h = –16t2 + 48t models the height, h, in feet, of the stick above the ground after t seconds. which inequality can be used to find the interval of time in which the stick reaches a height of more than 8 feet?
a.) –16t2 + 48t > 8
b.) –16t2 + 48t < 8
c.) –16t2 + 48t ³ 8
d.) –16t2 + 48t £ 8

A. )

Step-by-step explanation:

Given function that models the height ( in feet ),

If the height is more than 8 feet,

That is, h > 8,

Which is the required inequality that can be used to find the interval of time in which the stick reaches a height of more than 8 feet.

Option 'A' is correct.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
