I'll pick brainiest, pls help, also pls do not answer if you're going to tell me to download the work. The graph below shows the height of Cindy's model rocket during the course of its flight.

Which of these equations can be used to find the height of the rocket at any time during its flight?
A. y = 9x
B. y = x^2 - 81
C. y = -x^2 + 9x
D. y = 9 - 9x^2.

the answer is b i just did that

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
