Will give brainlest quick due in 5 mins A stunt person is shot out of a cannon from a platform 8 feet off of the ground. The height of the stunt person can be modeled as a function of time in seconds. The function is represented on the graph below. Enter the average rate of change for the height of the stunt person, measured as feet per second, between 0 seconds and 8 seconds.

lo.lll

step-by-step explanation:

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.  

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
