It is probably best to measure a volume of this size in Liters. This is a metric unit. There are 1000 liters in one cubic meter.

A store is having a sale in which all items are reduced by 20% including tax. Jennifer paid $21 for a pair of shorts if the sale

Julli [10]

Answer:
original price of pants = $25

Explanation:
First, let's calculate the price of shorts after discount:
Assume that the price of shorts after the discount is x
Total payment = price of shorts + taxes

We know that:
total payment = $21
taxes = 5% = 0.05 of the price

This means that:
21 = x + 0.05x
21 = 1.05x
x = $20

Therefore, the price of the shorts is $20 after the discount

Now, we will get the price of the shorts before the discount:
Assume that the price of shorts before discount is y

We know that:
The discount was 20%
This means that Jennifer paid:
100% - 20% = 80% of the price of the shorts

Therefore:
80% of the price = $20
0.8y = 20
y = $25

This means that price of shorts before discount was $25

Hope this helps :)

Describe the translation of the function from the parent function f(x) = x².

kkurt [141]

$\bf \qquad \qquad \qquad \qquad \textit{function transformations}
\\ \quad \\\\

\begin{array}{rllll} 
% left side templates
f(x)=&{{ A}}({{ B}}x+{{ C}})+{{ D}}
\\ \quad \\
y=&{{ A}}({{ B}}x+{{ C}})+{{ D}}
\\ \quad \\
f(x)=&{{ A}}\sqrt{{{ B}}x+{{ C}}}+{{ D}}
\\ \quad \\
f(x)=&{{ A}}(\mathbb{R})^{{{ B}}x+{{ C}}}+{{ D}}
\\ \quad \\
f(x)=&{{ A}} sin\left({{ B }}x+{{ C}} \right)+{{ D}}
\end{array}$

$\bf \begin{array}{llll}
% right side info
\bullet \textit{ stretches or shrinks horizontally by } {{ A}}\cdot {{ B}}\\\\
\bullet \textit{ flips it upside-down if }{{ A}}\textit{ is negative}
\\\\

\end{array}\\$

$\bf \begin{array}{llll}
\bullet \textit{ horizontal shift by }\frac{{{ C}}}{{{ B}}}\\
\qquad if\ \frac{{{ C}}}{{{ B}}}\textit{ is negative, to the right}\\\\
\qquad if\ \frac{{{ C}}}{{{ B}}}\textit{ is positive, to the left}\\\\
\bullet \textit{ vertical shift by }{{ D}}\\
\qquad if\ {{ D}}\textit{ is negative, downwards}\\\\
\qquad if\ {{ D}}\textit{ is positive, upwards}\\\\
\bullet \textit{ period of }\frac{2\pi }{{{ B}}}
\end{array}
$

now, notice the template above... now let's see your function $\bf y=x^2+4\implies 
\begin{array}{llllll}
y=&1(&1x&+&0)^2+&4\\
&A&B&&C&D
\end{array}$

so.. what do you think was the shift then?
