K + L + M = L + M + K is an example of Commutative Property of Addition

Commutative Property of Addition means the order of the terms doesn't matter. You can still get the same answer on both sides of the equation even though the order of numbers are not the same.

Example:
5 + 3 + 7 = 3 + 7 + 5
15 = 15

As you can see above, the sum of the left side of the equation is the same as the sum of the right side of the equation which is 15.

The lateral surface area of cone A is exactly 1/2 the lateral surface area of cylinder B. Cone A radius is r and height h - Cyli

Mrac [35]

The ratio of the <em>lateral surface</em> area of cone A to the <em>lateral surface</em> area of cylinder B is equal to $r = \frac{1}{2}\cdot \frac{\sqrt{r^{2}+h^{2}}}{h}$ . (Correct choice: False)

<h3>What is the ratio of lateral area of cone to the lateral area of the cylinder?</h3>

In accordance with <em>space</em> geometry, the <em>lateral</em> areas of the cone and cylinder are described by the following equations:

Cone

$A_{l} = \pi \cdot r \cdot \sqrt{r^{2}+h^{2}}$ (1)

Cylinder

$A_{l} = 2\pi\cdot r\cdot h$ (2)

If we divide (2) by (1), then we have the following ratio:

$r = \frac{1}{2}\cdot \frac{\sqrt{r^{2}+h^{2}}}{h}$

Find the inverse of the function y=2x^2+2

Tatiana [17]

The inverse of the function is y = $\sqrt{\frac{x - 2}{2}}$

In order to find this, you must start by switching the y and x values. Once you do this, you can solve for the new y value and that will be in inverse. The work is done for you below.

y = 2x^2 + 2 ---> switch x and y

x = 2y^2 + 2 ---> subtract 2 from both sides

x - 2 = 2y^2 ---> divide both sides by 2

$\frac{x-2}{2}$ = y^2 ---> take the square root of both sides.

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