2/4,6/12,1/4,3/12 make sure to label with miles cause it will probably be wrong hope this helps!
If we let V', A', and r' represent the rates of change of the volume, area, and radius of the sphere, we can differentiate equations for V and A in terms of r, then eliminate r' to get an equation for A' in terms of V'.
Then, for the given values, the surface area is increasing at the rate ...
... A' = (2/8)·25 ft²/s = 6.25 ft²/s
Answer:
(5,10)
Step-by-step explanation:
(-10x + 7y = 20)8 -80x + 56y = 160
(8x - 6y = -20)10 + 80x - 60y = -200
-4y = -40
y = 10
Plug 1 in for y into the first equation
-10x + 7(10) = 20
-10x + 70 = 20
- 70 - 70
-10x = -50
x = 5
