A tennis ball is tossed into the air. The height, h(t), in feet, of the tennis ball is a function of time, t, in seconds, as shown in the table below.
t h(t)
0 0
0.5 20
1 32
1.5 36
2 32
2.5 20
3 0
Which statement provides a correct interpretation of the average rate of change of this function from t=1.5 to t=3?
A
The average rate of change is 24, which means that the tennis ball was rising at an average speed of 24 ft/sec.

B
The average rate of change is 24, which means that the tennis ball was falling at an average speed of 24 ft/sec.

C
The average rate of change is −24, which means that the tennis ball was rising at an average speed of 24 ft/sec.

D
The average rate of change is −24, which means that the tennis ball was falling at an average speed of 24 ft/sec.

I don't want to answer because I'm not 100% sure, but I know you can eliminate C and D right off the bat, because the rate of change can't be negative. It is between A and B and out of those two I would say B.

I was gonna ask you to mark me brainliest if I was right, but I'm guessing this is for the IA4 where you can't see your grade... lol. Sorry, but I hope this helps you, at least a little bit

Answer is A

Step-by-step explanation:

I think that is the answer

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

y=x+9
