Acres of planted corn = (2/7) * (4/5)
= (2/7) * .8 = 1.6 / 7 acres = 0.2285714286 acres
The equation for a circle is
(x-h)^2 + (y-k)^2 = r^2
(-3,6)
-3 is h
6 is k
(x+3)^2 + (y-6)^2 = 10^2
10^2 = 100
(x+3)^2 + (y-6)^2 =100
The answer is B!
Answer:
You want to buy some golden apples. Each golden apple cost $2. How much much does golden apples pass cost?
y = total cost
x = amount of apple
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
