Answer:

The firston one is a scale factor of two and the second one is a scale factor of three.

Step-by-step explanation:

You just look at the coordinates. (1,1):(2,2) and (4,0):(8,0) and then for the second one (-1,0):(-3,0) and (3,2):(9,6).

1x2=2

4x2=8

-1x3=-3

3x3=9

2x3=6

Perimeter of the ΔJKL is 48 cm

Solution:

Given $\triangle \mathrm{RST} \sim \Delta \mathrm{JKL}$ .

RS = 8 cm and JK = 12 cm

Perimeter of $\triangle R S T$ = 32 cm

Let us find the perimeter of $\Delta J K L$ .

<u>Property of similarity triangles:</u>

If two triangles are similar, then the ratio of their perimeters is equal to the ratio of their corresponding sides.

$$\frac{\text{Perimeter of}\ \triangle RST }{{\text{Perimeter of}\ \triangle JKL}} =\frac{RS}{JK}$

$$\Rightarrow\frac{32 }{{\text{Perimeter of}\ \triangle JKL}} =\frac{8}{12}$

Do cross multiplication.

$$\Rightarrow 32\times 12 ={8}\times {\text{Perimeter of}\ \triangle JKL}$

$$\Rightarrow 384 ={8}\times {\text{Perimeter of}\ \triangle JKL}$

Divide both sides of the equation by 8.

$$\Rightarrow 48 = {\text{Perimeter of}\ \triangle JKL}$

Hence perimeter of the ΔJKL is 48 cm.

we conclude that the sequence has 8 terms.

<h3>How to get the number of terms in the sequence?</h3>

Here we have the geometric sequence:

2/81, 4/27, 8/9, ..., 6912

Notice that each term is equal to 6 times the previous term, such that:

2/81*6 = 4/27

4/27*6 = 8/9

Then the n-th term is equal to:

$a_n = a_1*r^{n-1}$

Where in this case:

$a_1 = 2/81\\\\r = 6$

Now we need to find the value of n such that:

$(2/81)*6^{n-1} = 6912\\\\6^n = 6*6812*(81/2) = 1,679,616$

If we apply the natural logarithm to both sides, then:

$n*ln(6) = ln(1,679,616)\\n = ln(1,679,616)/ln(6) = 8$

Then we conclude that the sequence has 8 terms.
