Step-by-step explanation:

Given that,

The diameter of the merry-go-round, d = 14 feet

Time taken, t = 6 seconds

Radius, r = 7 feet

The linear speed of the merry-go-round is given by :

v=\dfrac{2\pi r}{t}\\\\v=\dfrac{2\pi \times 7}{6}\\\\=7.33\ m/s

Also,

v=r\omega

Where

\omega is the angular speed

So,

\omega=\dfrac{v}{r}\\\\\omega=\dfrac{7.33}{7}\\\\=1.04\ rad/s

Hence, his linear and angular speeds are 7.33 m/s and 1.04 rad/s.

Ann Torbert purchased a truck for $11,000 on January 1, 2014. The truck will have an estimated salvage value of $1,000 at the en
alexandr402 [8]

Answer:

Balance in accumulated depreciation=\frac{10000}{Total Estimated Value}*Units of activity

Step-by-step explanation:

Salvage value=$1000

Purchased value=$11,000

In order to find the balance in accumulated depreciation at december 31,2015 using the units of activity we will use the following formula:

Balance in accumulated depreciation=\frac{10000}{Total Estimated Value}*Units of activity

In the above equation $10000 came from Purchased value - salvage Value

I need help I<br> don’t understand what the answer is!
SVETLANKA909090 [29]

Answer:

x = -4

Step-by-step explanation:

You kind of didn't capture the directions in your image, but it looks like maybe they want you to write the equation of the line.

So this is what you need to know: the equation of a vertical (up and down) line is

x = anumber

For future reference on the next question, the equation of a horizontal (flat, left and right) line is

y = anumber

For this question, though, it's vertical.

so x = -4

You can check by picking as many points as you like and find that they ALL have -4 as the x value. Also, you will find the slope formula gives you an answer that is undefined. That's why you can't write an equation using y=mx+b. Hope this helps! I can edit if the question is something wildly different for real.
