Answer:
Yes, they are
Step-by-step explanation:
y = -9x
Here y∝ x
Where -9 is constant of proportionality
If "y" increases by factor of 2, then "x" will also increases by factor of 2. Hence, y and x are " directly proportional" to each other.

Answer:

Step-by-step explanation:
![volume =  \frac{4}{3} \pi {r}^{3}  \\  \\ 288\pi =  \frac{4}{3} \pi {r}^{3} \\  \\ 3(288\pi) = 4\pi {r}^{3} \\  \\  \frac{3(288\pi)}{4\pi}  =  {r}^{3}  \\  \\ 216 =  {r}^{3}  \\  \\ r =  \sqrt[3]{216}  \\ r = 6](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20%7Br%7D%5E%7B3%7D%20%20%5C%5C%20%20%5C%5C%20288%5Cpi%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20%7Br%7D%5E%7B3%7D%20%5C%5C%20%20%5C%5C%203%28288%5Cpi%29%20%3D%204%5Cpi%20%7Br%7D%5E%7B3%7D%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B3%28288%5Cpi%29%7D%7B4%5Cpi%7D%20%20%3D%20%20%7Br%7D%5E%7B3%7D%20%20%5C%5C%20%20%5C%5C%20216%20%3D%20%20%7Br%7D%5E%7B3%7D%20%20%5C%5C%20%20%5C%5C%20r%20%3D%20%20%5Csqrt%5B3%5D%7B216%7D%20%20%5C%5C%20r%20%3D%206)

 
        
             
        
        
        
There is a decrease in power. It can be concluded that there has also been a change in: 
A) current or voltage.
