Answer:
S'(x)=-0.006x2+0.8x+9
Step-by-step explanation:
The rate of change of the sales S(x) with respect to the amount of money spent on advertising x is then the derivative of S(x) with respect to x. What we have to calculate is S'(x).
We know that the derivative of 
is 
(where a is a constant), and the derivative of a sum is the sum of the derivatives, so we can calculate the derivative of each term independently:
S'(x)=(−0.002x3 + 0.4x2 + 9x + 500)'=(−0.002)(3)x2 + (0.4)(2)x + 9
Which means:
S'(x)=-0.006x2+0.8x+9
Answer:
c) There are no black flies in Maine -> False
e) The moon is made of green cheese -> False
Explanation:
A proposition is a statement that poses an idea that can be True or False.
- Do not pass go, is not a proposition is an order, and there is not an answer to that statement.
- What time is it? Is not a proposition is a question and it's response goes beyond True or False.
- There are no black flies in Maine is indeed a proposition because is a statement that can either be True or False.
- 4 + x = 5 is not a proposition because is a statement with an infinite number of answers, in contrast, 4 + 1 = 5 is a proposition because is either True or False.
- The moon is made of green cheese is a proposition because is a statement that can either be True or False.
- 2 n ≥ 100 is not a proposition because is a statement with an infinity number of answer and is not clear whether is True or False, in contrast, 2 ≥ 100 is a proposition because is either True or False.
