Evaluate the integral. pls help me see the steps. thank you

Answer:

$-\frac{2}{15}(1-x)^\frac{3}{2}(3x+2)+C$

Step-by-step explanation:

Use the method of integration by parts. The method is based in the following rule of derivation of two functions f and g :

$(fg)' = f'g+fg'\implies fg'=(fg)'-f'g\implies \\\int fg' dx = fg -\int f'g dx$

Identify suitable f and g in the original expression. I use:

$f=x\,\,\,, \,\,\,g=\sqrt{1-x}\\f'=1\,\,\,,\,\,\,g'=-\frac{2}{3}(1-x)^\frac{3}{2}$

and write the integration by parts :

$\int x\sqrt{1-x} dx = -\frac{2}{3}x(1-x)^\frac{3}{2}+\frac{2}{3}\int (1-x)^\frac{3}{2}dx=\\ =-\frac{2}{3}x(1-x)^\frac{3}{2}-\frac{4}{15}(1-x)^\frac{5}{2}+C=\\=-\frac{2}{15}(1-x)^\frac{3}{2}(3x+2)+C$

with C an arbitrary integration constant.

Via monthly payments: ($100/mo)*(48 monts) = $4800, as opposed to $4000 cash. That's a difference of $800! Pay cash if y ou can.

A SOLUTION CONTAINS 60% WATER, 15% BLEACH AND THE

Allushta [10]

Answer:

20 ounces of cleaner

Step-by-step explanation:

Water 48 oz is 60% of unknown total. 60% = 3/5. Create equation and solve

48= 3x/5. 240= 3x. 80 = x

Total of water, bleach and cleaner is 80 ounces

60% + 15% = 75%

100% - 75%= 25% cleaner

.25 × 80 = 20 ounces
