Answer:

n=4

Step-by-step explanation:

First you subtract 8 from 15 which gives you 7 so it is n+3=7. then you subtract 3 from 7 which gives you 4.

Answer:

n = 4 and n = -10

Explanation:

l n + 3 l + 8 = 15

l n + 3 l = 7

Two solutions

n + 3 = 7

n = 4

and

n + 3 = -7 (since we are dealing with absolute numbers, one side has to be multiplied by -1)

n = -10

Answer:

0 ≤ m ≤ 7
0.4541 cm/month; average rate of growth over last 4 months of study

Step-by-step explanation:

Part A:

The study was concluded after 7 months. The fish cannot be expected to maintain exponential growth for any significant period beyond the observation period. A reasonable domain is ...

0 ≤ m ≤ 7

Part B:

The y-intercept is the value when m=0. It is the length of the fish at the start of the study.

Part C:

The average rate of change on the interval [3, 7] is given by ...

(f(7) -f(3))/(7 -3) = (4(1.08^7) -4(1.08^3))/4 = 1.08^3·(1.08^4 -1)

≈ 0.4541 cm/month

This is the average growth rate of the fish in cm per month over the period from 3 months to 7 months.
