Answer:

A. 16 m

B. At t = 2 and t = 6

C. 8 seconds

Step-by-step explanation:

Maximum height is at the vertex

(4,16). So maximum height is 16 m at t = 4

The rocket is at a height of 12m at two distinct times:

At 2 seconds and again at 6 seconds

The rocket is in air when the height is not zero, I.e between t=0 and t=8

8-0 = 8 seconds

a skateboard ramp has a slope 2/5.Which is the angle the ramp makes with the ground? A.66 degrees B. Not here C.24 degrees D.22

vovikov84 [41]

We are given with the slope of a ramp that is equal to 2/5, that is x = 5 and y = 2. In this case, we can find the angle of elevation by using the formula: tan Ф = y/x
using a calculator (inverse tangent or arctangent), Ф = 21.8 degrees. In this case, the answer is D. 22 degrees.
