Can someone please help me with this....differentiate,, y=(cos(x)^x

N76 [4]

$y=\cos^xx=e^{\ln\cos^xx}=e^{x\ln\cos x}$

Now differentiate, applying the chain rule on the right hand side.

$\dfrac{\mathrm dy}{\mathrm dx}=e^{x\ln\cos x}\dfrac{\mathrm d}{\mathrm dx}[x\ln\cos x]$
$\dfrac{\mathrm dy}{\mathrm dx}=e^{x\ln\cos x}\left(\ln\cos x-\dfrac{x\sin x}{\cos x}\right)$
$\dfrac{\mathrm dy}{\mathrm dx}=e^{x\ln\cos x}\left(\ln\cos x-x\tan x\right)$
$\dfrac{\mathrm dy}{\mathrm dx}=\cos^xx\left(\ln\cos x-x\tan x\right)$

Fofino [41]

Answer:

22 1/4 feet

Step-by-step explanation:

you can sketch this problem to be a right triangle with a hypotenuse of 24 feet and one leg of 9 feet (17 - 8).

use Pythagorean Theorem to find the base side, which represents the distance between the posts

a² + 9² = 24²

a² + 81 = 576

a² = 576 - 81

a² = 495

a = $\sqrt{495}$

a = $\sqrt{9}$ · $\sqrt{55}$ = 3 $\sqrt{55}$ , which is approx 22.25
