we have M is durectly porpotional to r^2
so M=(k)r^2
and when r=2, m=14
so 14=(k)(2)^2
k=14/4 =7/2
so when r=12
m= (7/2)(12)^2 =(7/2)(144) = 504
Answer:

Step-by-step explanation:
A polynomial is given to us . We need to find the value of c so that it is divisible by (x-3 ) .The given polynomial to us is ,
And the factor is ,

Now , according to factor theorem , p(x) will be divisible by g(x) if p(-3) = 0

<h3>
<u>Hence </u><u>the </u><u>value </u><u>of </u><u>c </u><u>is </u><u>(</u><u>-</u><u>1</u><u>4</u><u>)</u><u>/</u><u>3</u><u> </u><u>.</u></h3>
Answer:
I think the answer is D please forgive me if I'm wrong

Let

, where

, so that

. Then the ODE is




This is separable, so you have

Integrate both sides, solving for

if possible, then replace using

and solve for

if possible.
