B would equal logx (-2x^5/a)-2

A would equal -2x^3-b (The b is up there with the 3 as well. Like ^3-b)

Answer:

option D. 126 cm

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

Triangles PQR and XYZ are similar by AA Similarity Theorem

$\frac{XY}{PQ}=\frac{YZ}{QR}=\frac{XZ}{PR}$

Let

z ---> the scale factor

$z=\frac{XY}{PQ}$

substitute the given values

$z=\frac{30}{5}=6$

step 2

Find the perimeter of triangle XYZ

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let

z ----> the scale factor

p_1 ----> the perimeter of triangle XYZ

p_2 ---> the perimeter of triangle PQR

$z=\frac{p_1}{p_2}$

The perimeter of triangle PQR is

$p_2=5+10+6=21\ cm$

we have

$z=6\\p_2=21\ cm$

substitute

$6=\frac{p_1}{21}$

$p_1=6(21)=126\ cm$

therefore

The perimeter of triangle XYZ is 126 cm

Answer:

rice --- no of people

1 ---- 3

2 ---- 6

4 ---- 12

12 --- 36

43 --- 129

Step-by-step explanation:

This is in direct proportion. The constant value of it is 3 so you have to multiply the number of cups into three to get the number of people it can feed

An equilateral triangle has a height of 10 feet. How long is one of its sides? (Note: In an equilateral triangle, all sides have

lidiya [134]

Answer:

side length is $\frac{20\sqrt{3} }{3}$ feet

Step-by-step explanation:

An equilateral triangle has a height of 10 feet. the height of the triangle is the perpendicular bisector to the base

so it forms a two right angle triangle

the triangle formed is a 30-60-90 degree triangle

the diagram is attached below

Let x be the side if the equilateral triangle

sin(theta)=opposite by hypotenuse

$sin(60)=\frac{10}{x}$

$\frac{\sqrt{3}}{2} =\frac{10}{x}$

cross multiply

$\sqrt{3} x=20$

$x=\frac{20}{\sqrt{3} } =\frac{20\sqrt{3} }{3}$

please explain to me I don't understand why x -2 less than/ equal to 0 but x + 4<0...I don't understand why the inequalities
