Answer:
(a)
(b)P'(5)=-($4.54) Thousand
(c)P'(11)=-($2.10) Thousand
(d)The fifth Month
Step-by-step explanation:
Given the monthly profit model:
(a)We want to derive a model that gives the Marginal Profit, P' of the book.
We differentiate
using quotient rule.
Simplifying
We have derived a model for the marginal profit.
(b) After 5 months, at t=5
Marginal Profit=P'(5)
=-($4.54) Thousand of dollars
(c)Marginal Profit 11 Months after book release
=-($2.10) Thousand of dollars
(d) Since the marginal profit at t=5 is negative, after the 5th Month, the profit starts to experience a steady decrease.
6 x 2 + 4 x 3 = 12 + 12 = 24
Answer:
Reflection over y-axis
Step-by-step explanation:
We know that with a reflection of the x-axis, we flip the value of the y value
But since the y-values in Q3 and Q4 are both negative, we know that can't be the case
So it has to be a reflection over the y-axis where the x-values are flipped
