What dos the average rate of change tell you about the rocket

B

average rate simply means, a constant rate something is moving about during a certain period.

now, object quite often or most always do not move at some constant speed, but the average rate gives a ballpark of how it must be moving.

so, since in this case the "slope" or average rate is a positive 6, one can say the rocket is higher at t = 3 than at t = 1.

Step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
