Step-by-step explanation:
Since size of the pizza determines the amount of calories.
Let us say that a 2" x4" strip of pizza has 250 calories.
Then a pizza of twice the size (or 4" x 4") will have twice as many calories (500 calories) .
Answer:
Joe's Plumbing charges more per hour ($45) than Mark's Plumbing (S40)
Step-by-step explanation:
Let
t ------> the number of hours
J(t) ---->the total amount in dollars that Joe's Plumbing charges
M(t) ---->the total amount in dollars that Mark's Plumbing charges
we know that
The linear equation in slope form is equal to

where
m is the slope or rate of the linear equation
b is the y-intercept (initial value)
In this problem we have
<em>Joe's Plumbing</em>

The slope or rate is equal to


Mark<em>'s Plumbing</em>

The slope or rate is equal to


therefore
Joe's Plumbing charges more per hour ($45) than Mark's Plumbing (S40)

Step-by-step explanation:
We used the given expression for the wind power:
replacing the power (on the left hand side of the equal sign) by 15.83 MegaWatts, and then solve for v which is raised to the power 3:
![P(v)=0.002713v^3\\15.83=0.002713v^3\\\frac{15.83}{0.002713} =v^3\\v^3=5834.87\\v=\sqrt[3]{5834.87} =18.003\frac{m}{s}](https://tex.z-dn.net/?f=P%28v%29%3D0.002713v%5E3%5C%5C15.83%3D0.002713v%5E3%5C%5C%5Cfrac%7B15.83%7D%7B0.002713%7D%20%3Dv%5E3%5C%5Cv%5E3%3D5834.87%5C%5Cv%3D%5Csqrt%5B3%5D%7B5834.87%7D%20%3D18.003%5Cfrac%7Bm%7D%7Bs%7D)
