Hi!

The answer should be third option.

$20+4j\ge 2\left(j+20\right)$

$20+4j\geq 2j+40$

$20+4j-20\geq 2j+40-20$

$4j\geq 2j+20$

$4j-2j\geq 2j+20-2j$

$2j\geq 20$

$\frac{2j}{2}\geq \frac{20}{2}$

$Answer ---> j\geq 10$

Explanation: <u><em>First you had to subtract by the 20 from both sides. Then simplify it gave us 4j ≥ 2j+20. You can also subtract by the 2j from both sides. Then simplify its going to be 2j≥20. Next, you can also divide by 2 from both sides, and it gave us the answer is j≥10 is the right answer. Hope this helps! And thank you for posting at here on Brainly. And have a great day. -Charlie</em></u>

Y=sech(tan‐¹x) find the derivative

Klio2033 [76]

Recall that

d/dx sech(x) = - sech(x) tanh(x)

d/dx tan⁻¹(x) = 1/(1 + x²)

Then by the chain rule,

dy/dx = - sech(x) tanh(x) / (1 + x²)
