Aperson standing on the roof of a building throws a ball directly upward. the ball misses the rooftop on its way down andeventually strikes the ground. the function5(1) - - 16: 1 + 64! + 80describes the ball’s height above the ground, sit), in feet, tseconds after it was thrown. a. fund the balls average velocity between the time it was thrown and 2 seconds later. b. find the ball’s average velocity between 2 and 4 seconds after it was thrown. c. what do the signs in your answers to parts (a) and (b) mean in terms ofthe direction of the ball’s motion?

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
