Answer:

Suppose the Proportional relationship bettween two variables x and y, is

y=mx

→Rate of Change that is unit Rate is equal to

$\frac{dy}{dx}=m$

Where, m=tan Ф,where Ф , is the angle made by line with positive direction of x axis.

So, if you have calculated unit rate of change, it will help you to draw the graph accurately, because you know the angle made by line with positive direction of x axis.

$\mathsf{2^6}\\\mathsf{\rightarrow2\times2\times2\times2\times2\times2}\\\mathsf{\rightarrow 4\times4\times4}\\\mathsf{\rightarrow 16\times4}\\\mathsf{\rightarrow \bf 64}$

$\mathsf{4 - 64}\\\mathsf{\rightarrow \bf -60}$

$\mathsf{= \dfrac{8(\bf -60)}{4}}$

$\mathsf{8(-60)}\\\mathsf{\rightarrow \bf -480}$

HELP FAST PLEASE!!<br> FIND THE SURFACE AREO OF EACH RECTANGULAR PRISM

tatyana61 [14]

The surface area of the rectangular prism is 3668.94 m²

<h3>Calculating Surface area </h3>

From the question, we are to determine the surface area of the rectangular prism

Surface area of a rectangular prism is given by the formula,

Surface area = 2(lw + lh + wh)

Where l is the length

w is the width

and h is the height

From the given diagram,

l = 35.7 m

w = 25.5 m

h = 15.1 m

Putting the parameters into the formula, we get

Surface area = 2(35.7×25.5 + 35.7×15.1 + 25.5×15.1)

Surface area = 2(910.35 + 539.07 + 385.05)

Surface area = 2(1834.47)

Surface area = 3668.94 m²

Hence, the surface area of the rectangular prism is 3668.94 m²
