I think it is 135 mi to the 2 power
Because 44 is a bigger number than 4 it is 11 times bigger so the difference is larger than a proportional number
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:
He is correct
Step-by-step explanation:
12=100%
15 is 3 more than 12
12 divided by 3 is 4
100 divided by 4 is 25
100 + 25 = 125
The sum of 14 and 16 is 30.30 times 4 is 120.
