A marine biologist is studying the growth of a particular species of fish. She writes the following equation to show the length of the fish, f(m), in cm, after m months:

f(m) = 5(1.07)m

Part A: When the marine biologist concluded her study, the length of the fish was approximately 9.19 cm. What is a reasonable domain to plot the growth function? (4 points)

Part B: What does the y-intercept of the graph of the function f(m) represent? (2 points)

Part C: What is the average rate of change of the function f(m) from m = 1 to m = 9, and what does it represent? (4 points)

23.75 + [(0.18)(23.75)]

Step-by-step explanation:

Ellen plans to leave an 18% tip with her $23.75 lunch bill.

Therefore, to determine her total bill, she use the expression

= 23.75 + ( 18% of 23.75 )

= 23.75 + ( 0.18 × 23.75 )

or 23.75 + [(0.18)(23.75)]

So the expression is 23.75 + [(0.18)(23.75)] to determine her total bill.
