Nesterboy [21]

Answer:

<h2>823.7 m²</h2>

Step-by-step explanation:

If a figure A and a figure B are similar, then

\dfrac{area_A}{area_B}=k^2    (*)

<em>k</em><em> - similarity scale</em>

<em />

Calculate the similarity scale:

k=\dfrac{6}{5}

We have the surface area of the smaller prism 572 m².

Substitute to the formula (*):

\dfrac{x}{572}=\left(\dfrac{6}{5}\right)^2\\\\\dfrac{x}{572}=\dfrac{36}{25}\qquad\text{cross multiply}\\\\25x=(36)(572)\\\\25x=20,592\qquad\text{divide both sides by 25}\\\\x=823.68\approx823.7\ m^2

What is this graph ?
Eva8 [605]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

x-y=1      <em>subtract x from both sides</em>

-y=-x+1     <em>change the signs</em>

y=x-1

It's a linear function.

We need only two points to plotting a graph.

We choose any three values of x and calculate y.

for\ x=0\to y=0-1=-1\to(0,\ -1)\\for\ x=1\to y=1-1=0\to(1,\ 0)\\for\ x=2\to y=2-1=1\to(2,\ 1)
