Answer:

c

Step-by-step explanation:

the surface area of a cylinder = 2πr² + 2πrH

π = pi

r = radius = 1

H = height = 3

2 x π x 1² + 2 x  π x 1 x 3 = 2π + 6π = 8π cm²

Complete the point slope equation of the line through(-1,-10)and(5,2).<br>y-6=​
Lynna [10]

Answer:

<h2>y - 6 = 2(x - 7)</h2>

Step-by-step explanation:

The point-slope of an equation of a line:

y-y_1=m(x-x_1)

m - slope

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the poinys (-1, -10) and (5, 2). Substitute:

m=\dfrac{2-(-10)}{5-(-1)}=\dfrac{12}{6}=2

Put the value of the slope and the coordinateso f the point (5, 2), to the equation of a line:

y-2=2(x-5)

In the question we have y - 6 = ...

Therefore

y-2=2(x-5)    <em>subtract 4 from both sides</em>

y-6=2(x-5)-4          <em>use the distributive property</em>

y-6=2x-10-4

y-6=2x-14      <em>distributive</em>

y-6=2(x-7)

What number is 32% of 1,000
Jlenok [28]
It is 320 because if you divide 1000 by 10, you would get 100 (which would be equal to 10% of 1000) So if you multiply 100x3=300. then, 2% of 100 is 20, so you add that to 300 then you 320
