Answer:
Option 3 3 1/8x - 6 3/10
Step-by-step explanation:
(3 1/2x - 4 1/10) - (3/8x + 2 1/5)
Divide it into parts:
(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)
3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x
-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10
So we get:
2 1/4x - 6 3/10
r+s^2
4+1^2

Cani get the brainliest please
Remember, the volume formula of a sphere is
![\frac{4}{3} \pi r^{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B3%7D%20%20%5Cpi%20%20r%5E%7B3%7D%20)
.
Set that equation equal to whatever volume they give you and solve for r.
![\frac{4}{3} \pi r^{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D%20)
=
![\frac{9}{16} \pi](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B16%7D%20%5Cpi)
Now solve for r! I know you can do this. If you need help, just comment.

Answer :
C
Solution :
At any instant x2+y2=52
Differentiating w.r.t. time 2xxdt+2ydydt=0
Here dxdt=2,dydt=u⇒u=83m/s
