How do I do number 9?

Answer:

The correct option is C. The function [tex]f(x)=\frac{5}{4}(\frac{4}{5})^x[/tex] is a stretch of an exponential decay function.

Step-by-step explanation:

The general form of an exponential function is

[tex]f(x)=ab^x[/tex]

where, a is the initial value and b is the growth factor.

If b<1, then it represents a decay function and if b>1, then it represents a growth function.

Let k be a stretch and compression factor.

[tex]g(x)=kf(x)[/tex]

If k<1, then it represents vertical compression and if k>1, then it represents vertical stretch.

In third function

[tex]f(x)=\frac{5}{4}(\frac{4}{5})^x[/tex]

[tex]k > 1[/tex]

[tex]b < 1[/tex]

Therefore the function [tex]f(x)=\frac{5}{4}(\frac{4}{5})^x[/tex] is a stretch of an exponential decay function.

The question is an illustration of trigonometry ratio, and the tangent of the angle is 12/13

Let the angle be x.

The sine of the angle is given as:

sin(x) = 5/13

The sine of an angle is calculated using:

sin(x) = opposite/hypotenuse

By Pythagoras theorem, we have:

Hypotenuse^2 = Adjacent^2 +Opposite^2

This gives

13^2 = Adjacent^2 + 5^2

Rewrite as:

Adjacent^2 = 13^2 - 5^2

Evaluate

Adjacent^2 = 144

Take the square root of both sides

Adjacent = 12

The tangent is then calculated using

tan(x) = Adjacent/Hypotenuse

So, we have:

tan(x) = 12/13

Hence, the tangent of the angle is 12/13

First, how many ways are there for the 1st poster?

It can be the first, the 2nd, the 3rd, the 4th, or the 5th.

How many ways are there for the 2nd poster?

there are 4 ways, because one of them is occupied by the first poster

There are 3 ways for the 3rd poster, 2 ways for the 4th poster and 1 way for the 5th poster.

Multiply the number of ways together : 120 ways

These are the ways we can arrange the 5 posters ↓

We could replace P1 (Poster 1) with any of the 4 posters here, and do the same thing with the other posters...

Overall, believe it or not, there are 120 ways to arrange these 5 posters.

There are 120 different ways the posters can be arranged in a row

from the question, we have the following parameters that can be used in our computation:

Number of posters = 5

This means that

n = 5

The different ways the posters can be arranged in a row is calculated as

Ways = n!

So, we have

Ways = 5!

Expand

Ways = 5 * 4 *3 * 2 * 1

Evaluate

Ways = 120

Hence, the number of ways is 120

the question states that a person named Ben has two copies of the same poster having different sizes , provided they both are squares !

further , we've been given that the side length of the posters are in the ratio of 3:7 and the perimeter of the smaller posted is 27 cm .

We've been asked to find the perimeter of the bigger poster !

so let's start ~

[tex]let\: the \: length \: of \: the \: smaller \: poster \: be \: 3x \\ \\ let \: the \: length \: of \: the \: bigger \: poster \: be \: 7x \\ \\ now \: , \: \\ \\ perimeter \: of \: square = 4 \times side \\ \\ \implies \: perimeter \: of \: shorter \: square = 4 \times 3x \\ \\ \implies \: 27 = 3x \\ \\ x = \cancel\frac{27}{3} \\ \\ \implies\red{\boxed{ \: x = 9 \: cm}}[/tex]

now ,

[tex]side \: length \: of \: bigger \: square = 7x \\ \\ \implies \: 7 \times 9 = 63 \: cm \\ \\ \therefore \: perimeter \: of \: bigger \: square = 4 \times 63 \\ \\ \bold\pink{\implies \: 252 \: cm}[/tex]
