Answer: Option A x>38
Step-by-step explanation:
I took the test and got 100% on it.
All you have to do is plug in the x and y values for each ordered pair into the left hand side of the equation and see if you get 15 = 15. If you do, the ordered pair is a solution; otherwise it is not a solution. For example, let's try (-2,-3); that is x = -2 and y = -3:
2x - 9y = 15
2(-2) - 9(-3) = 15
-4 - (-27) = 15
-4 + 27 = 15
23 = 15
This is obviously not true, so (-2,-3) is not a solution. Now you try it on each of the ordered pairs given in the problem statement.
Answer:
1545.66 rad/h
Step-by-step explanation:
We need to find the angular velocity in rad/hour when wind is moving with a speed of 4.1 rpm.
We know that,
1 revolution = 2π rad
1 hour = 60 minute
So,
![4.1\ rmm = 4.1\times \dfrac{2\pi }{(\dfrac{1}{60})}\ rad/h\\\\=1545.66\ rad/h](https://tex.z-dn.net/?f=4.1%5C%20rmm%20%3D%204.1%5Ctimes%20%5Cdfrac%7B2%5Cpi%20%7D%7B%28%5Cdfrac%7B1%7D%7B60%7D%29%7D%5C%20rad%2Fh%5C%5C%5C%5C%3D1545.66%5C%20rad%2Fh)
So, the required angular velocity is 1545.66 rad/h.
