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

The correct option is A.

Step-by-step explanation:

The function for height of the stick above the ground after time t is given as

Where, h is height of the stick above the ground in feet and t is time in seconds.

We have to find the interval of time in which the stick reaches a height of more than 8 feet. It means

8" class="latex-formula" id="TexFormula2" src="https://tex.z-dn.net/?f=h%3E8" title="h>8">

Using the given function, we get

Therefore option A is correct.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
