Answer:
<em><u>d = 8</u></em>
Step-by-step explanation:
2(d -6) - 3 = 1
+3 +3
2(d-6) = 4
/2 /2
(d-6) = 2
+6 +6
(d) = 8
<u><em>d = 8</em></u>

Answer:
Step-by-step explanation:
(f + g)(x) simply means that you are adding together the 2 functions that are written in terms of x.

The only like terms we have there are the x-cubed's, so

Answer:
9 represents the initial height from which the ball was dropped
Step-by-step explanation:
Bouncing of a ball can be expressed by a Geometric Progression. The function for the given scenario is:

The general formula for the geometric progression modelling this scenario is:

Here,
represents the initial height i.e. the height from which the object was dropped.
r represents the percentage the object covers with respect to the previous bounce.
Comparing the given scenario with general equation, we can write:
= 9
r = 0.7 = 70%
i.e. the ball was dropped from the height of 9 feet initially and it bounces back to 70% of its previous height every time.
