Suppose x is any positive number why is circle 1 similar to circle

Mathematics
1 answer:
Nostrana [21]3 years ago
3 0

Answer:

A circle 2 is a dilation of circle 1 with a scale factor of 5

Step-by-step explanation:

We have been given information about two circles as given below:

circle 1: center (0,0) and radius 2x

circle 2: center (0,0) and radius 10x .

Now we need to find about why is circle 1 similar to circle where x is any positive number.

We know that all circles are similar. So after dilation it doesn't affect their similarities.

10x can be obtained from 2x, by multiplying  2x with 5.

So the first choice "A circle 2 is a dilation of circle 1 with a scale factor of 5" is correct.

What is an equation for the line with slope 2/3 and 7-intercept 9? 30 points to whoever answers this correctly and gets brainlie
Annette [7]

The equation of the line is y = \frac{2}{3} x + 9

Step-by-step explanation:

The equation of a line in slope-intercept form is y = m x + b, where

  • m is the slope of the line
  • b is the y-intercept ⇒ the value of y when x = 0

∵ The line has a slope \frac{2}{3}

∴ m = \frac{2}{3}

∵ The y-intercept is 9

∴ b = 9

- Substitute the values of m and b in the form of the equation below

∵ y = m x + b

∴ y = \frac{2}{3} x + 9

The equation of the line is y = \frac{2}{3} x + 9

Lilit [14]
Hey there Ag484p1stit,

Answer:

Rent = 25% x $3,400
         = $850
Left now = $3,400 - $850
               = $2,550
Transportation = 30% x $2,550
                        = $765.
She spends $765 on transportation.

Hope this helps :D
