Answer:
k = -64
Step-by-step explanation:
I'll assume that you meant "(1/4)k." Please use parentheses in cases such as this one.
Subtract 17 from both sides, obtaining (1/4)k = -16.
Multiply both terms of this result by 4 to eliminate the fraction 1/4:
k = -64
C(x)=rx+s we are told that x=3, c(x)=21, and s=3
21=3r+3 divide both sides by 3
7=r+1 subtract 1 from both sides
6=r so now c(x) becomes:
c(x)=6x+3
To find the area to be surrounded by a gravel path, we need to calculate two areas. First, the area of the whole space and, second, the area of the pond. We subtract these values to obtain the actual area for the gravel path.
A(whole space) = pi x (250)^2 = 62500π ft^2
A(pond) = pi x 200^2 = 40000π ft^2
Actual Area = 62500π ft^2 - 40000π ft^2 = 70686 ft^2 ----> OPTION A
