Eduardo is painting a rectangular wall that is 96 inches high and 110 inches long. What is the area of the wall?

EastWind [94]

<h3>Required Answer:-</h3>

Here the height and length are the sides of the rectangular wall and we have to find the area.

Area of rectangle is given by:

$= l \times b$

where l is the length and b is the breadth/width according to the question. Plugging the given values:

$= 110 \times 96 \: {inch}^{2}$

$= 10560 \: {inch}^{2}$

<h3>Hence:-</h3>

The area of the wall is 10560 inch²

You live in a big apartment. The bedroom is 15 by 20 feet. Calculate the area of your bedroom.

Natasha_Volkova [10]

Answer:

The answer is B 300 sq. ft.

Step-by-step explanation:

If you multiply 15 by 2 you were to get 30 but since it is 15 multiplied by 20 instead its like adding a 0 at the end of the number so we change 30 to 300.

Hope this helps :)

If the graph of the function h defined by =hx+−4x23 is translated vertically downward by 9 units, it becomes the graph of a func

KengaRu [80]

Hmmm I can't quite make it the h(x) function, look like $h(x)=4x^{23}$ dunno

however, a vertical transformation or shift of 9 units is just a -9
so hmm notice here
$\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}}
\end{array}$

$\begin{array}{llll}
% right side info
\bullet \textit{ stretches or shrinks horizontally by } {{ A}}\cdot {{ B}}\\
\bullet \textit{ horizontal shift by }\frac{{{ C}}}{{{ B}}}\\
\qquad if\ \frac{{{ C}}}{{{ B}}}\textit{ is negative, to the right}\\
\qquad if\ \frac{{{ C}}}{{{ B}}}\textit{ is positive, to the left}\\
\bullet \textit{ vertical shift by }{{ D}}\\
\qquad if\ {{ D}}\textit{ is negative, downwards}\\
\qquad if\ {{ D}}\textit{ is positive, upwards}
\end{array}$
