A wheel with radius 1 foot makes 1 revolution in 4 seconds. What is the linear velocity, in feet per second, of a point on the e

Alex

Answer:

$v=\dfrac{\pi}{2}\ ft/s$

Step-by-step explanation:

Given that,

A wheel with radius 1 foot makes 1 revolution in 4 seconds

We need to find the linera velocity of a point on the edge of the wheel. We know that, the linear velcity is given by :

$v=r\omega$

Where

$\omega$ is angular velcocity, $\omega=2\pi\ rad$

$\omega=\dfrac{1}{4}\times 2\pi\\\\=0.5\pi\ rad/s$

$v=1\times 0.5\pi\\\\v=\dfrac{\pi}{2}\ ft/s$

So, the linear velocity of the wheel is equal to $\dfrac{\pi}{2}\ ft/s$ .

Express as a trinomial. (x−8)(2x+9)

Tomtit [17]

Basically expand
use FOIL (a way to remember distributive property)
first outer inner last
that is th eorder to multiply them
First: x times 2x=2x²
Outer: x tmes 9=9x
Inner: -8 times 2=-16x
last: -8 times 9=-72
add them

2x²+9x-16x-72
2x²-7x-72
