What is the inner function in y=(3x+1)5y=(3x+1)^5y=(3x+1)5?
A
dVdt=0.02π m3 s−1\frac{dV}{dt}=0.02\pi\text{ m}^3\text{ s}^{-1}dtdV=0.02π m3 s−1
B
3x+13x+13x+1
C
ddx(cos(g(x)))=\frac{d}{dx}\left(\cos(g(x))\right)=dxd(cos(g(x)))= −sin(g(x))g′(x)\boxed{-\sin(g(x))g'(x)}−sin(g(x))g′(x).
D
If VVV depends on rrr and rrr depends on ttt, then dVdt=dVdrdrdt\boxed{\frac{dV}{dt}=\frac{dV}{dr}\frac{dr}{dt}}dtdV=drdVdtdr.
