Answer:

So the perimeter of the larger rectangle = 160

Step-by-step explanation:

We are given the scale factor of the two rectangles. We are given the perimeter of the smaller rectangle = 120.

Since the two rectangles are scaled, this means they have a common ratio. In other words:

\frac{perimeter \: of \: larger \: rectangle}{perimeter \: of \: smaller \: rectangle}  =   \frac{4}{3}

As given in the question.

Now we know the smaller rectangle has a perimeter of 120.

Let's take the perimeter of the larger rectangles as x.

\frac{x}{120}  =  \frac{4}{3} \\ \\ multiplying \: both \: sides \: by \: 120 \\  x =  \frac{4}{3} (120) \\ x = 160

So the perimeter of the larger rectangle = 160

\text{We know that the average rate of change of a function f(x) on inerval [a,b] is}\\
\\
f_{avg}=\frac{f(b)-f(a)}{b-a}\\
\\
\text{so using this the average rate of chang of g for x on interval }[3,7] \text{ is}\\
\\
g_{avg}=\frac{g(7)-g(3)}{7-3}\\
\\
=\frac{4-1}{4}\\
\\
=\frac{3}{4}\\
\\
\text{so average rate of change of g on interval [3,7] is }\frac{3}{4}

\\(ii)\\  \text{Average rate of chang of f for x on interval }[3,7] \text{ is}\\
\\
f_{avg}=\frac{f(7)-f(3)}{7-3}\\
\\
=\frac{0-5}{4}\\
\\
=\frac{-5}{4}\\
\\
\text{so average rate of change of g on interval [3,7] is }\frac{-5}{4}

\\(iii)\\
\text{Since g(4)=5, so we have}\\
\\
f(g(4))=f(5)\\
\\
\text{since the value of f is 1 at x=5. so }\\
\\
f(g(4))=f(5)=1\\
\\
\text{hence we have, }f(g(4))= 1

\\(iv)\\
\text{Since f(3)=5, so we have}\\
\\
g(f(3))=g(5)\\
\\
\text{since the value of g is 2 at x=5. so }\\
\\
g(f(3))=g(5)=2\\
\\
\text{hence we have, }g(f(3))= 2

What substance has a mass of 148g and a volume of 40cm3 ?
rusak2 [61]

The substance that has a mass of 148g and a volume of 40cm³ is   3.7g/cm³

In order to get the substance that has a mass of 148g and a volume of 40cm³, we need to first get the density of the substance.

Density is the ratio of mass per unit volume of a substance

Density = Mass/Volume

Given the following:

Mass = 148g

Volume = 40cm³

Density = 148/40

Density = 3.7g/cm³

Hence the density of the substance is 3.7g/cm³
