neonofarm [45]

Answer:

$\omega = 8\,\frac{rad}{s}$

Step-by-step explanation:

The translation speed of the wheel is:

$v=\frac{20\,m}{5\,s}$

$v=4\,\frac{m}{s}$

The angular speed of the wheel is:

$\omega = \frac{4\,\frac{m}{s} }{0.5\,m}$

$\omega = 8\,\frac{rad}{s}$

-8 + 3h = 1 <br>i need help its a 2 step equation

LekaFEV [45]

Answer:

h = 3

Step-by-step explanation:

-8 + 3h = 1

Add 8 to both sides.

3h = 1 + 8

Add 1 and 8 to get 9.

3h = 9

Divide both sides by 3.

h = $\frac{9}{3}$

Divide 9 by 3 to get 3.

h = 3

Anybody knows the answer real quick

eduard

Answer:

I think it's 3

Step-by-step explanation:

To calculate the gradient equals to

y(1)-y(2)

-----------

x(1)-x(2)

So - 5 - 1 = - 6

6 - 2 = 4

-6 - 3

--- = ----- x

4 2

And the first y intercept is 1 so I guess it's 3.

Just for refernece, not sure if I'm correct. Sry
