Answer:

it is about 1.13 so the closest would be letter A.

Step-by-step explanation:

$A=4\pi r^{2}$ We plug it into this formula

$r=\frac{1}{2} \sqrt{\frac{A}{\pi } } =\frac{1}{2} *\sqrt{\frac{16}{\pi } }$ This gives us ≈1.12838

Answer:

$P(x) = -0.25x^2 + 42x - 90$

Step-by-step explanation:

Given

$C(x) = -17x + 90$

$R(x) =- 0.25x^2 + 25x$

Required

Determine the profit function.

Profit function is calculated as thus:

$P(x) = R(x) - C(x)$

So, we have:

$P(x) = -0.25x^2 + 25x -(-17x + 90)$

$P(x) = -0.25x^2 + 25x + 17x - 90$

$P(x) = -0.25x^2 + 42x - 90$
