Answer:
B) T = 2πr/v
Step-by-step explanation:
To solve the given equation for T, multiply it by T/v.
![v=\dfrac{2\pi r}{T}\\\\v\dfrac{T}{v}=\dfrac{2\pi r}{T}\cdot\dfrac{T}{v}\\\\T=\dfrac{2\pi r}{v} \qquad\text{simplify}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B2%5Cpi%20r%7D%7BT%7D%5C%5C%5C%5Cv%5Cdfrac%7BT%7D%7Bv%7D%3D%5Cdfrac%7B2%5Cpi%20r%7D%7BT%7D%5Ccdot%5Cdfrac%7BT%7D%7Bv%7D%5C%5C%5C%5CT%3D%5Cdfrac%7B2%5Cpi%20r%7D%7Bv%7D%20%5Cqquad%5Ctext%7Bsimplify%7D)
Answer:
Yes.
Step-by-step explanation:
Yes.
Assuming a, b and c are integers (not = 0)
a/b + b/c
= (ac + b^2) / bc which is a rational number.
The graph represents y=-4x-1
If you notice the line, it goes past the -1 on the y axis which indicates that the y intercept is -1 since that was the only choice which displayed this, we know that our answer is y=-4x-1
(1,4), (-1,3) 3-4/-1-1=-1/-2. -1/-2= 1/2 so 1/2 would be the slope
Answer:
Option (4)
Step-by-step explanation:
Definition of a ray states that a segments which connects two points but extending only in one direction infinitely is called as Ray.
Opposite rays will have a common end but the direction of the arrows will be different.
Therefore, from the picture attached,
Opposite rays will be PA and PB.
Option (4) will be the correct option.
