A cylindrical can has a volume of 2in^(3). Express the surface area of the can as a function of its radius,r.

noname [10]

$V=2 \text{ in}^3\\
A=2\pi r (r+h)\\
h=?\\\\
V=\pi r^2h=2\\
\pi r^2h=2\\
h=\dfrac{2}{\pi r^2}\\
A=2\pi r\left(r+\dfrac{2}{\pi r^2}\right)\\
\boxed{A=2\pi r^2+\dfrac{4}{r}}

Write the equation of the line in point slope form that passes through (-1, -2) and ( 1, 4).

Musya8 [376]

Answer:

y+2= 3(x+1)

Step-by-step explanation:

First you need to find slope by using y2-y1/x2-x1

you should get 3 for your slope(m)

Them you chose any point iḿ using (-1, -2)

The formula for point slope form is...

y-y1=m(x-x1)

plug those numbers in and you get

y + 2 = 3(x + 1)
