83. Martina had $231. She spent 3/7 of her money on new

1 answer:

8 0

She spent 3/7 of 231 on clothes. So she spent (3/7)*231 = $99

Now she has 231-99 = $132 left

She spent (2/3) of 132 on shoes and purse. So she spent (2/3)*132 = $88

At the end she has 132-88 = $44 left

The graphs below have the same shape. What is the equation of the blue<br> graph?

Triss [41]

The blue graph is translated 3 units to the left and two down, so the new equation would be g(x)=(x-3)^2-2

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