Answer:
Look just at finding the linear model. Two points. Use price per gallon for x and gallons per hour sold for y. Your two points (x,y) are (2.15,1600) and (2.55,800).
Slope m=%281600-800%29%2F%280.15-0.55%29
m=800%2F0.40
m=2000
Using point-slope form for a line, and the lower-y point,
y-800=2000%28x-2.55%29
highlight%28y=2000%28x-2.55%29%2B800%29
Hello!
To calculate the sale price of the coat, we can simply multiply 150 by .40, then subtract the product from 150.
150 × .40 = 60
150 - 60 = 90
The sale price of the coat is $90.
if the minute hand of the <u>circular clock</u> is 28 inches, that simply means its radius is 28.
![\bf \textit{area of a circle}\\\\A=\pi r^2~~\begin{cases}r=radius\\[-0.5em]\hrulefill\\r=28\end{cases}\implies A=\pi 28^2\implies A=784\pi](https://tex.z-dn.net/?f=%5Cbf%20%5Ctextit%7Barea%20of%20a%20circle%7D%5C%5C%5C%5CA%3D%5Cpi%20r%5E2~~%5Cbegin%7Bcases%7Dr%3Dradius%5C%5C%5B-0.5em%5D%5Chrulefill%5C%5Cr%3D28%5Cend%7Bcases%7D%5Cimplies%20A%3D%5Cpi%2028%5E2%5Cimplies%20A%3D784%5Cpi)
so it covers that much in 1 rotation, so in 4 rotations that'd be 4(784π) => 3136π.
