goldfiish [28.3K]

Answer:

$\large\boxed{f'(x)=\dfrac{12x^2}{\sqrt{2x^3-1}}}$

Step-by-step explanation:

$f(x)=4\sqrt{2x^3-1}=4\left(2x^3-1\right)^\frac{1}{2}\\\\f'(x)=4\cdot\dfrac{1}{2}(2x^3-1)^{-\frac{1}{2}}\cdot3\cdot2x^2=\dfrac{12x^2}{(2x^3-1)^\frac{1}{2}}=\dfrac{12x^2}{\sqrt{2x^3-1}}\\\\\text{used}\\\\\sqrt{a}=a^\frac{1}{2}\\\\\bigg[f\left(g(x)\right)\bigg]'=f'(g(x))\cdot g'(x)\\\\\bigg[nf(x)\bigg]'=nf'(x)\\\\(x^n)'=nx^{n-1}$

Simplify the following expression. 5(4 + 3c) - 12

Vsevolod [243]

Answer:

5(4 + 3c) - 12 = 15c + 8

Step-by-step explanation:

1st step, expand it to make it a little easier to solve, 20 + 15c - 12

2nd step, subtract, 20 - 12 = 8

3rd step simplify, 15c + 8

12R<br> If V= ---- <br> (r+R)<br> Make R the subject of the equation .

k0ka [10]

V= $\frac{12R}{r+R}$
note, r and R are differnt
so multipl both sides by (r+R)
V(r+R)=12R
distribute
Vr+VR=12R
minus VR from both sides
Vr=12R-VR
undistribute R
Vr=R(12-V)
divide both sides by (12-V)
$\frac{Vr}{12-V}=R$ or
$R= \frac{Vr}{12-V}$
