Answer:
Step-by-step explanation:
This is modeled after an exponential function which, at its simplest, is
where, for us and in this particular situation, y is the final height, a is the initial height, b is the rate of growth or decline, and x is the number of bounces. We know the initial height is 20, but we need to find the rate of decline. Rewriting the formula to model a rate of decay or decline is
, or more closely related to our circumstances:
and simplifying that a bit:
, choice D.
Answer:You already have the slope add a x on the 4.13 and y on 6,-2.

Okay, so this is a right angle. That means it is 90 degrees.
So far we know that on side of the angle is 47 degrees.
To get the other angle we will just subtract 90 - 47 = 43
