Answer:
The answer is "
"
Step-by-step explanation:





Calculating the surface area:
![=\int^{2\pi}_{0} \int^{5}_{4} 4 \ du \ dv \\\\=\int^{2\pi}_{0} 4[4]^{5}_{4} \ dv \\\\=\int^{2\pi}_{0} 4[5-4] \ dv \\\\=\int^{2\pi}_{0} 4 \ dv \\\\=4 [v]^{2\pi}_{0}\\\\= 4 \times 2\pi\\\\= 8\pi](https://tex.z-dn.net/?f=%3D%5Cint%5E%7B2%5Cpi%7D_%7B0%7D%20%5Cint%5E%7B5%7D_%7B4%7D%204%20%5C%20du%20%5C%20dv%20%5C%5C%5C%5C%3D%5Cint%5E%7B2%5Cpi%7D_%7B0%7D%204%5B4%5D%5E%7B5%7D_%7B4%7D%20%20%5C%20dv%20%5C%5C%5C%5C%3D%5Cint%5E%7B2%5Cpi%7D_%7B0%7D%204%5B5-4%5D%20%5C%20dv%20%5C%5C%5C%5C%3D%5Cint%5E%7B2%5Cpi%7D_%7B0%7D%204%20%5C%20dv%20%5C%5C%5C%5C%3D4%20%5Bv%5D%5E%7B2%5Cpi%7D_%7B0%7D%5C%5C%5C%5C%3D%204%20%5Ctimes%202%5Cpi%5C%5C%5C%5C%3D%208%5Cpi)
M = -3, m = -9/3
because when you divide -9/3, you get -3, so the slopes would be the same.
If the slopes are the same (and their intercepts are different) then that pair of slopes represents parallel lines!
There is not enough information. Do you need an equation?
Answer:
240 divide by 6 is 40. the mph is 40
Forumla for circumference is
pi x diameter
or
pi x 2 x radius
so we are going to use the second formula to estimate the answer without a calculator.
3 x 2 x 125
3 x 2 =6
6 x 125 = 750.
the closest answer is 785m. That is the answer.
