Answer:

c = -10

Step-by-step explanation:

16c -24=4c -144

Subtract 4c from both sides

16c - 4c - 24 = 4c - 4c - 144

12c - 24 = -144

Add 24 to both sides

12c -24 + 24 = -144 + 24

12c = -120

Note: -144 + 24 = -120

12c = -120

Divide both sides by 12

12c/12 = -120/12

c = -10

Note: 12/12 = 1 and -120/12 = -10

Checking :

16c -24=4c -144

Put c = -10

16(-10) - 24 = 4(-10) - 144

-160 - 24 = -40 - 144

-184 = -184

Therefore

c = -10

I hope this was helpful, please rate as brainliest

Answer:

c= -10

Step-by-step explanation:

16c-24=4c-144

+24 +24

16c=4c-144+24

16c=4c-120

-4c -4c

12c=-120

:12 :12

c=-120/12

c= -10

Use the definition of the derivative to differentiate v=4/2 pie r^3

nata0808 [166]

I suspect 4/2 should actually be 4/3, since 4/2 = 2, while 4/3 would make V the volume of a sphere with radius r. But I'll stick with what's given:

$\displaystyle \frac{dV}{dr} = \lim_{h\to0} \frac{2\pi(r+h)^3-2\pi r^3}{h}$

$\displaystyle \frac{dV}{dr} = 2\pi \lim_{h\to0} \frac{(r^3+3r^2h+3rh^2+h^3)- r^3}{h}$

$\displaystyle \frac{dV}{dr} = 2\pi \lim_{h\to0} \frac{3r^2h+3rh^2+h^3}{h}$

$\displaystyle \frac{dV}{dr} = 2\pi \lim_{h\to0} (3r^2+3rh+h^2)$

$\displaystyle \frac{dV}{dr} = 2\pi \cdot 3r^2 = \boxed{6\pi r^2}$

In Mathematica, you can check this result via

D[4/2*Pi*r^3, r]
