I know one way could be:
(3 × (-6)) + (5 × (-6)) = -18 + (-30) = -48

The compiled enrolled in the three grades at Willmar middle is 977. There are 356 students in the seventh grade and 365 in the e

Julli [10]

977- (356+365) = x

356+365= 721

977- 721 = 256

x= 256

A cone has a radius of 200 m at its base. The cone is 50 m high. How much space is inside the cone?

Sauron [17]

The question "how much space is inside a solid?" is actually asking about the volume of that solid.

The volume of a cone is given by

$V = \dfrac{1}{3}\pi hr^2$

where h is the height of the cone, and r is its radius.

So, you only need to plug in the values:

$V = \dfrac{1}{3}\pi\cdot 50 \cdot 200^2 = \dfrac{2000000\pi}{3}m^3$

ASAP! find the inverse of the function y=2x^2+2

jeka57 [31]

Answer:

$\displaystyle y=\sqrt{\frac{1}{2}x -1}$

Step-by-step explanation:

We want to find the inverse of the function:

$y=2x^2+2$

To find the inverse of a function, we will flip the variables and solve for <em>y</em>. So:

$x=2y^2+2$

Solve for <em>y</em>. Subtract two from both sides:

$x-2=2y^2$

Divide both sides by two:

$\displaystyle y^2=\frac{1}{2}x-1$

And take the principal square root of both sides. Therefore:

$\displaystyle y=\sqrt{\frac{1}{2}x -1}$
