Answer: The value of x must be 7 units.

Step-by-step explanation:

Since we have given that

ABCD is a parallelogram.

Suppose that AC and BD intersect at o.

So, AO = OC.

And we have given that

AO = 5x

OC = 6x-7

According to question,

$5x=6x-7\\\\5x-6x=-7\\\\-x=-7\\\\x=7$

Hence, the value of x must be 7 units.

Find f'(x) if f(x) = (2/(x^1/3)) + 3 cos x + x^pi

galben [10]

The derivative of $f$ is

$f'(x)=\left(2x^{-1/3}+3\cos x+x^\pi\right)'$

$f'(x)=\left(2x^{-1/3}\right)'+(3\cos x)'+\left(x^\pi\right)'$

By the power rule,

$f'(x)=-\dfrac23x^{-4/3}+(3\cos x)'+\pi x^{\pi-1}$

The derivative of $\cos x$ is $-\sin x$ :

$f'(x)=-\dfrac23x^{-4/3}-3\sin x+\pi x^{\pi-1}$
