Find the indefinite integral. (Use C for the constant of integration.)

mart [117]

Answer:

$\int\ {(3x^2-2x+1)\,(x^3-x^2+x)^7} \, dx = \frac{1}{8} (x^3-x^2+x)^8+C$

tep-by-step explanation:

In order to find the integral:

$\int\ {(3x^2-2x+1)\,(x^3-x^2+x)^7} \, dx$

we can do the following substitution:

Let's call

$u=(x^3-x^2+x)$

Then

$du = (3x^2-2x+1) dx$

which allows us to do convert the original integral into a much simpler one of easy solution:

$\int\ {(3x^2-2x+1)\,(x^3-x^2+x)^7} \, dx = \int\ {u^7 \, du = \frac{1}{8} \,u^8 +C$

Therefore, our integral written in terms of "x" would be:

$\int\ {(3x^2-2x+1)\,(x^3-x^2+x)^7} \, dx = \frac{1}{8} (x^3-x^2+x)^8+C$

The perimeter of a parallelogram is 72 meters. The width of the parallelogram is 4 meters less than its length. Find the length

Sidana [21]

Answer:

length = 20 mt

Width = 16 mt

Step-by-step explanation:

Let the length of the field be x

width of the field be y

Hence formula of the perimeter is given as

P=2(x+y)

P=72(given)

72=2(x+y)

Dividing both sides by 2 we get

x+y=36---(A)

Also given that width of the parallelogram is 4 meters less than its length

Hence

y=x-4

or x-y=4 ---(B)

Adding A and B

2x=40

x=20

y=x-4

y=20-4=16

Hence length = 20 mt

Width = 16 mt
