When it says varies directly, it means that y and x are going to be on opposite sides of the equals sign and that there is a constant, k,
y=kx
Plug in (5,100)
100=k(5)
K=20
Answer:
A
Step-by-step explanation:
<h2>pi divided by four</h2>
Step-by-step explanation:
Let the angle in degrees be ![a](https://tex.z-dn.net/?f=a)
Let the angle in radians be ![r](https://tex.z-dn.net/?f=r)
If
is the angle in degrees and
is the angle in radians,
![a\times \frac{\pi }{180}=r](https://tex.z-dn.net/?f=a%5Ctimes%20%5Cfrac%7B%5Cpi%20%7D%7B180%7D%3Dr)
It is given that the ![a=45](https://tex.z-dn.net/?f=a%3D45)
![r=\frac{\pi}{180}\times a= \frac{\pi}{180}\times 45=\frac{\pi}{4}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B%5Cpi%7D%7B180%7D%5Ctimes%20a%3D%20%5Cfrac%7B%5Cpi%7D%7B180%7D%5Ctimes%2045%3D%5Cfrac%7B%5Cpi%7D%7B4%7D)
So,![r=\frac{\pi}{4}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B%5Cpi%7D%7B4%7D)
