Answer:

C) 960

Step-by-step explanation:

Let's expand the factorial.

n! = 1*2*3*4*...n

6! = 1*2*3*4*5*6

3!= 1*2*3

The given expression $\frac{8. 6!}{3!} \\$

= $\frac{8.1.2.3.4.5.6 }{1.2.3}$

Canceling out the common terms, we get

= $\frac{8.4.5.6}{1} \\$

= 8.4.5.6 [here . represents multiplication]

= 960

Answer: C) 960

Thank you.

Use integration by parts to find the integrals in Exercise.<br> ∫(4x-12)e-8x dx.

stepladder [879]

Answer:

$e(2x^{2} -12x)-4x^{2}+C$

Step-by-step explanation:

We have been given an indefinite integral as $\int \left(4x-12\right)e-8x\:dx$ . We are asked to find the given integral.

Let us solve our given problem.

$\int \left(4x-12\right)e\:dx-\int 8x\:dx$

Take out constant:

$e\int \left(4x-12\right)\:dx-8\int x\:dx$

$e(\int 4x\:dx -\int 12\right\:dx)-8\int x\:dx$

$e(\frac{4x^{1+1}}{2} -12x)-8*\frac{x^{1+1}}{1+1}+C$

$e(\frac{4x^{2}}{2} -12x)-8*\frac{x^{2}}{2}+C$

$e(2x^{2} -12x)-4x^{2}+C$

Therefore, our required integral would be $e(2x^{2} -12x)-4x^{2}+C$ .
