Age at BBM 2019 Question Group 'A Brief answer questions; 1. Integrate the following: S(ax? + 2bx + c)3/2(2xa + 2b) dx 2.

worty [1.4K]

If the integral is

$\displaystyle \int (ax^2+2bx+c)^{3/2}(2ax+2b)\,\mathrm dx$

substitute $u = ax^2+2bx+c$ and $\mathrm du=(2ax+2b)\,\mathrm dx$ . Then you end up with

$\displaystyle \int u^{3/2}\,\mathrm du = \frac25u^{5/2} + C$

which in terms of <em>x</em> is

$\boxed{\dfrac25(ax^2+2bx+c)^{5/2} + C}$

A customer bought a car and paid $1,080 in sales tax. The sales tax rate is 6%. What was the price of the car before the tax?

Helga [31]

Okay. So you have the amount of take, and the tax rate.
To find tax you multiply the amount (x) by the percent of tax in decimal form.
So:
.06x = $1,080
x = $18,000

Someone plz help me with this

Phoenix [80]

Answer:

$5y^{6}\sqrt{2}$

Step-by-step explanation:

We want to simplify:

$\sqrt{50y^{12}}$

We rewrite as:

$\sqrt{2\times25 \times (y^{6})^2}$

We split the radical sign to obtain:

$\sqrt{25} \times \sqrt{(y^{6})^2} \times \sqrt{2}$

Simplify the square root for the perfect squares to get:

$5y^{6}\sqrt{2}$

Therefore the simplified form is: $5y^{6}\sqrt{2}$
