The diagram shows two nested triangles that share a vertex.Find a center and a scale factor for a dilation that would move the l

nasty-shy [4]

Transformation that changes the size of a shape is referred to as dilation.

The scale factor that moves the large triangle to the small one is 1/5
The center of dilation is: (-1,1)

The center of dilation

From the diagram (see attachment), the triangles share a common vertex at (-1,1)

This means that, the center of dilation is (-1,1)

The scale factor of dilation

To do this, we divide the side length of the small triangle with the corresponding side of the large triangle.

From the attached image:

$\mathbf{Base\ of\ small\ triangle = 1}$

$\mathbf{Base\ of\ large\ triangle = 5}$

So, the scale factor (k) from large to small is:

$\mathbf{k = \frac{Base\ of\ small\ triangle}{Base\ of\ large\ triangle} }$

$\mathbf{k = \frac{1}{5} }$

You can walk 3 miles per hour, jog 5 miles per hour, or run 10 miles per hour. You go a full hour before changing pace. At the e

Studentka2010 [4]

Answer:

b. How many ways arc there to go 12 miles?

≡ p(12) = 25

c. How many ways arc there to go 20 miles?

≡ p(20) = 131

d. How many ways arc there to go 22 miles?

≡p(22) 199

Step-by-step explanation:

a) supposed you walked for the first hour. Then you would have travelled 3 miles. if you jogged you would have covered 5miles and if you run you would have covered 10miles. now you have to decide how to run the rest miles from the n miles.

Thus, the number of ways one can cover n miles will be given by the recurrence relation

p(n) = p( n-3) + p( n-5) + p( n - 10)

now to solve the rest of the question, let us make a table which provides the number of ways for n = 1 to 22.

check the attachment for the table

b. How many ways arc there to go 12 miles?

≡ p(12) = 25

c. How many ways arc there to go 20 miles?

≡ p(20) = 131

d. How many ways arc there to go 22 miles?

≡p(22) 199

Hey! Solving linear equations with integers! i don’t think it should be that hard since it’s practice, I just need some help wit

Dmitriy789 [7]

Solution 1 :-

>> -3 (3 - x) = 2x + 5

>> -3 × (3 - x) = 2x + 5

>> -9 + 3x = 2x + 5

>> 3x - 2x = 9 + 5

>> x = 14

Solution 2 :-

>> -6 - 9p = 3p

>> -9p - 3p = 6

>> -12p = 6

>> p = -1/2

Solution 3 :-

>> -5 (-4 - a) = 3a + 8

>> -5 × (-4 - a) = 3a + 8

>> 20 + 5a = 3a + 8

>> 5a - 3a = 8 - 20

>> 2a = -12

>> a = -12 / 2

>> a = -6

Solution 4 :-

>> s - 6 = -5s

>> s + 5s = 6

>> 6s = 6

>> s = 6 / 6

>> s = 1
