Answer:
9
Step-by-step explanation:
We want to evaluate

for A=-3.
This means, we need to substitute A=-2, into the given equation and simplify.
We substitute to get:

In this case the base is -3, so it multiplies itself twice.

This gives us:

First you must find slope using two points (2,7.5) and (-1,0).
0-7.5 = -7.5
-1-2 = -3
-7.5/-3 = 2.5
y - 0 = 2.5 ( x + 1)
y - 0 = 2.5x + 2.5
y = 2.5x + 2.5
Sample Response: There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.
If you divide those two you get <span>0.0024691358 hope that helped</span>
It would be 1/3rd because your last number would be 4 in the equation of 12 sandwiches.
