Answer:

(5,7)

Step-by-step explanation:

The coordinates are ordered by x (horizontal) then y (vertical).

So the coordinates are

x = 5

y = 7

the coordinate pair is therefore (5,7).

What is x^2=7x number 9

ipn [44]

Let's do this in steps, show your work!

#1. We need to move all terms to one side.

x^2 - 7x = 0

#2. Then factor out the common term x.

x(x - 7) = 0.

#3. Simplify to get..

x = 0, 7.

If you need help with any other question let me know.

A water wheel has a radius of 9 feet. The wheel is rotating at 5 revolutions per minute. Find the linear speed, in feet per mi

guajiro [1.7K]

Answer:

$90\pi\text{ ft/s}\approx282.74\text{ ft/s}$

Step-by-step explanation:

Refer to physics equation $v=\omega r$ , where $\omega$ is angular velocity.

Angular velocity's SI unit is rad/s. Convert rev/min to rad/s:

$\displaystyle 5\text{ rev/min}=5\cdot \frac{1}{60}\cdot 2\pi\approx 0.524\text{ rad/s}$

Now substitute $\displaystyle\omega=\frac{1\pi}{6}$ and $r=9$ into $v=\omega r$ :

$\displaystyle v=\frac{1\pi}{6}\cdot 9=\frac{3}{2}\pi\text{ ft/s}=\boxed{90\pi\text{ ft/s}}$
