Answer: Not proportional

=======================================================

Explanation:

Let's assume the two fractions are equal.

If so, then,

$\frac{0.2}{2.6} = \frac{0.3}{3.6}\\\\0.2*3.6 = 2.6*0.3\\\\0.72 = 0.78$

The last equation is false, so the first equation is false.

Therefore, the two ratios are <u>not</u> proportional.

-------------

Another approach:

Calculate the decimal value of each fraction

$\frac{0.2}{2.6} \approx 0.07692\\\\\frac{0.3}{3.6} \approx 0.08333\\\\$

The two ratios result in different decimal values, so the two ratios are not equal, aka not proportional.

How do you solve this question? Differentiate:

madreJ [45]

Answer:

$\displaystyle \frac{d}{dx}[x\sqrt{x}-x^{2}\sqrt{x}]$

$\displaystyle =\frac{3}{2}\sqrt{x} - \frac{5}{2}\;x\sqrt{x}$

Step-by-step explanation:

There's no need for the product rule. Consider the following:

$\sqrt{x}$ is the same as $x^{1/2}$

As a result,

$x\sqrt{x} = x\cdot x^{1/2} = x^{3/2}$ , and
$x^{2}\sqrt{x} = x^{2}\cdot x^{1/2} = x^{5/2}$ .

$\displaystyle x\sqrt{x}-x^{2}\sqrt{x} = x^{3/2} - x^{5/2}$ .

How to differentiate the first term, $x^{3/2}$ ?

Apply the power rule.

$\displaystyle \frac{d}{dx} [x^{3/2}] = \underbrace{3/2}_{\begin{aligned}&\text{from}\\[-0.5em]& \text{power}\end{aligned}} \;x^{(3/2) - 1} = \frac{3}{2}\;x^{1/2}$ .

$\displaystyle \frac{d}{dx} [x^{5/2}] = \underbrace{5/2}_{\begin{aligned}&\text{from}\\[-0.5em]& \text{power}\end{aligned}} \;x^{(5/2) - 1} = \frac{5}{2}\;x^{3/2}$ .

The derivative of difference is the difference of derivatives. Rewrite $x^{1/2}$ back as $\sqrt{x}$ since the question uses square roots rather than fraction power.

$\displaystyle\begin{aligned} \frac{d}{dx}[x\sqrt{x}-x^{2}\sqrt{x}] &=\frac{d}{dx}[x\sqrt{x}] - \frac{d}{dx}[x^{2}\sqrt{x}] \\&=\frac{3}{2}\;x^{1/2} - \frac{5}{2}\;x^{3/2}\\ &=\frac{3}{2} \sqrt{x} - \frac{5}{2} x\sqrt{x}\end{aligned}$ .

Find the distance AB given these coordinates: A(3,6),B(-2,4)

vampirchik [111]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\ \quad \\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&A&(~{{ 3}} &,&{{ 6}}~) 
% (c,d)
&B&(~{{ -2}} &,&{{ 4}}~)
\end{array}~~ 
% distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}
\\\\\\
AB=\sqrt{(-2-3)^2+(4-6)^2}\implies AB=\sqrt{(-5)^2+(-2)^2}
\\\\\\
AB=\sqrt{25+4}\implies AB=\sqrt{29}$

Pls help it isn't hard I'm just having trouble.

NikAS [45]

Answer:According to my calculations, an item with an original price tag of $54.50 that is marked down by 20% will have a sales price of $43.60 -- a savings of $10.90.

If you include the sales tax savings ($0.82 ) your total savings would add up to $11.72.
