gregori [183]

Answer:

LxWxH

Step-by-step explanation:

Volume can be calculated by using the formula: (length) x (width) x (height)

In this particular question, you are given the length as 13cm, the width as 8cm, and the height of 22cm.

To obtain the volume, you should plug these numbers into the formula (length) x (width) x (height)

When plugged in, the equation should look like this: (13cm) x (8cm) x (22cm).

When 13 x 8 x 22 =2288cm

Since you are calculating the volume, the answer will be given in centimeters cubed, so your final answer will be 2,288cm^3

Hope this explanation helps :)

Line E passes through the points (2, 3) and (4, -3). What is the slope of a line perpendicular to line E?
lilavasa [31]
\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
%  (a,b)
&&(~ 2 &,& 3~) 
%  (c,d)
&&(~ 4 &,& -3~)
\end{array}
\\\\\\
% slope  = m
slope =  m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-3}{4-2}\implies \cfrac{-6}{2}\implies \cfrac{-3}{1}

now, a line perpendicular to that one, will have a "negative reciprocal" slope, thus

\bf \textit{perpendicular, negative-reciprocal slope for}\quad \cfrac{-3}{1}\\\\
negative\implies  +\cfrac{3}{ 1}\qquad reciprocal\implies +\cfrac{ 1}{3}\implies \cfrac{1}{3}
