Answer:

Every point on a horizontal line has the same y-value. Use the y-value of the point to find the equation of the horizontal line.

y=4

You would start out with multiplying giving you 5(x+6). then you would have a product of 5x+30. hoped this helped!

K=mv^2/2 solve for v

matrenka [14]

Answer: $v=\sqrt[]{\frac{2K}{m} }$

Step-by-step explanation:

$K=\frac{mv^2}{2}$

First, multiply by 2 to get rid of the 2 in the denominator. Remember that if you make any changes you have to make sure the equation keeps balanced, so do it on both sides as following;

$2*K=\frac{mv^2}{2}*2$

$2K=mv^2$

Divide by m to isolate $v^2$ .

$\frac{2K}{m}=\frac{mv^2}{m}$

$\frac{2K}{m} =v^2$

To eliminate the square and isolate v, extract the square root.

$\sqrt[]{\frac{2K}{m} }=\sqrt[]{v^2}$

$\sqrt[]{\frac{2K}{m} }=v$

let's rewrite it in a way that v is in the left side.

$v=\sqrt[]{\frac{2K}{m} }$

A park has a large circle painted in the middle of the playground area.thecircle is divided into 4 equal sections And each secti

lilavasa [31]

Answer:

The area of each section of the circle is $25\pi\ m^{2}$

Step-by-step explanation:

we know that

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=10\ m$

substitute

$A=\pi (10^{2})=100\pi\ m^{2}$

To find the area of each section divide the complete area of the circle by $4$

$100\pi\ m^{2}/4=25\pi\ m^{2}$

prohojiy [21]

Answer:

y = $\sqrt{19^2 + 8.2^2}$

Step-by-step explanation:

to get the hypotenuse:

use the Pythagorean theorem:

a² + b² = c²

where a = 19, b = 8.2 c = y

plugin values:

19² + 8.2² = y²

y = $\sqrt{19^2 + 8.2^2}$
