A line passes through (3, –2) and (8, 2).

The point-slope form:
$y-y_1=m(x-x_1)$
m - slope
(x₁,y₁) - point

$(3,-2) \\
x_1=3 \\ y_1=-2 \\ \\
(8,2) \\
x_2=8 \\ y_2=2 \\ \\ \hbox{the slope:} \\
m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-(-2)}{8-3}=\frac{2+2}{5}=\frac{4}{5} \\ \\ \hbox{the point-slope form:} \\
y-y_1=m(x-x_1) \\
y-(-2)=\frac{4}{5}(x-3) \\
\boxed{y+2=\frac{4}{5}(x-3)}$

$\hbox{the standard form:} \\
y+2=\frac{4}{5}(x-3) \\
y+2=\frac{4}{5}x-\frac{12}{5} \\
-\frac{4}{5}x+y=-\frac{12}{5}-2 \ \ \ |\times 5 \\
-4x+5y=-12-10 \\
\boxed{-4x+5y=-22}$

The answer is D.

Answer:

The volume is 2224.96632 or 2224.97(if rounded)

Step-by-step explanation:

First of all, I divided the diameter by two to find the radius:

16.2/2=8.1

Then I used the formula:

V =4/3 πr³

I hope this helps

Which polar coordinates represent the same point as (4, −π/2)

marin [14]

You can go full 2π rotate around counterclockwise so the angle wouldn't be negative.

So -π/2 + 2π = -π/2 + 4π/2 = 3π/2

So (4, 3π/2) is the same point as (4, -π/2)
