Answer:

Step-by-step explanation:
we know that
The equation of a exponential growth function is given by

where
y is the population
x is the time in years since year 2015
a is the initial value
r is the rate of change
we have

substitute


In the year 2040 the value of x is equal to

substitute

Volume = base area x height
Base area = 6 (1/2 x 3 x 2.6) = 23.4 cm²
Volume = 23.4 x 7 = 164 cm³ (nearest wole number)
Answer: Volume = 164 cm³
Given:
L = W - 4
P = 2L + 2W
We can substitute 2L for 2(W - 4) = 2W - 8
So:
2W - 8 + 2W = P
P = 4W - 8
Answer is 4. 4W-8
