Answer:
C(x) = $60 + ($79.17/unit)x
Step-by-step explanation:
The linear cost function is represented by a straight line with slope $60/unit and y-intercept $60:
C(x) = $60 + ($9500/120 units)x, or
C(x) = $60 + ($79.17/unit)x
Answer:
79
Step-by-step explanation:
A square that has side length
has area
.
A circle that has a diameter 20 feet has area ![A=\frac{\pi d^2}{4}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B%5Cpi%20d%5E2%7D%7B4%7D)
We substitute the diameter into the formula to obtain;
![A=\frac{\pi \times 20^2}{4}=100\pi ft^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B%5Cpi%20%5Ctimes%2020%5E2%7D%7B4%7D%3D100%5Cpi%20ft%5E2)
The number of squares that has area 4 feet square that can fit into a circle with area
is
![=\frac{100\pi}{4}=25\pi=78.5398](https://tex.z-dn.net/?f=%3D%5Cfrac%7B100%5Cpi%7D%7B4%7D%3D25%5Cpi%3D78.5398)
When we round to the nearest whole number; we have 79 squares.
2+4a=-10
First, subtract 2 from both sides.
4a=-12
Then divide 4 from both sides.
a=-3
