Find the length of the circumference:

Circumference = 2 x pi x radius

Circumference = 2 x 3.14 x 7

Circumference = 43.96 kilometers

90 degrees is 1/4 of a circle ( 360/4 = 90)

Arc length = 43.96/4 = 10.99 kilometers

Help for 15 points . ill up it

Step-by-step explanation:

Let $P_1(-1, -8)\:\text{and}\:P_2(-4, -9)$

The slope of the line through these two points is

$m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{(-9 + 8)}{(-4 + 1)} = \dfrac{1}{3}$

So the slope-intercept form of the line passing through the two points is

$y = mx + b = \frac{1}{3}x + b$

To find b, we use either point into our equation. Let's use (-1, -8):

$-8 = \frac{1}{3}(-1) + b \Rightarrow b = -\dfrac{23}{3}$

Therefore, the slope-intercept form of the equation for the line is

$y = \dfrac{1}{3}x - \dfrac{23}{3}$

The standard form of the equation can be written as

$x + 3y + 23 = 0$

How do you find the percent of increase from 12 to 18?

olga nikolaevna [1]

Let's get the data out of the problem:

Nv = 18

Ov = 12

Now, we can apply in this equation that relates the new and the old values:

i = Nv / Ov

i = 18 / 12

i = 1.5

Now, we just consider what has passed from 1, and this is 0.5, converting to percentage it is:

p = 0.5 . 100

p = 50%

The increase was 50%.

Hope it helps.

3x-9=2x+4
3x-9+9=2x+4+9
3x=2x+13
3x-2x=2x-2x+13

Check:
3(13)-9=2(13)+4
39-9=26+4
