There are 360° in a circle, now, this "sector" of the circle has an angle of 70°, so for 70°, there are 8in or circumference, or arc length

how much arc length or circumference in 360° then?

well $\bf \begin{array}{ccllll}
degrees&circumference\\
-----&--------\\
70&8\\
360&x
\end{array}\implies \cfrac{70}{360}=\cfrac{8}{x}$

solve for "x"

Suppose the total cost of producing x units of a certain commodity is c(x) = 6x4 − 30x3 − 54x2 + x + 2. determine the largest an

liraira [26]

To determine the marginal cost of the production, one needs to derive the given equation for the cost,

c(x) = 6x4 - 30x3 - 54x2 + x + 2

The derivative of the equation in terms of x is as reflected below.

c'(x) = 24x3 - 90x2 - 108x + 1

Equate the derivative to zero in order to determine the value of x .

c'(x) = 0 = 24x3 - 90x2 - 108 + 1

The value of x from the equation is 4.025.

Substituting x to the original equation,

c(x) = -1254.35 and at c(0) = 2
