Use the slope formula y2-y1/x2-x1

3-(-7)/1-(-1) = 10/2 = 5

To find the y-intercept:

y=5x+b

3=5(1)+b

3 = 5+b

-5 -5

-2=b

The equation of the line that passes through (-1,-7) and (1,3) is

y=5x-2

Cerrena [4.2K]

Answer:

The perimeter of the dog run will use 67.2 feet of fencing.

Step-by-step explanation:

First find how long the width is.

24 * 2/5 = 9.6

The width of the fence is 9.6 feet.

To find the total perimeter, add double the length and width.

24 * 2 = 48

9.6 * 2 = 19.2

48 + 19.2 = 67.2

You fly a hot air balloon 3.5 miles above the ground. What is the measure of BD⌢, the portion of Earth that you can see? Round y

STatiana [176]

Answer:

$\Delta s \approx 334.545\,m$

Step-by-step explanation:

Let assume that Earth is a sphere, the following trigonometric diagram is constructed and presented below. The central angle is given by this inverse trigonometric equation:

$\theta = 2\cdot \cos^{-1} \left(\frac{r}{r+h} \right)$

$\theta = 2\cdot \cos^{-1}\left(\frac{4000\,mi}{4000\,mi+3.5\,mi} \right)$

$\theta = 4.792^{\circ}$

The distance of the portion of Earth that can be seen is:

$\Delta s = \frac{4.792^{\circ}}{360^{\circ}}\cdot (2\pi)\cdot (4000\,mi)$

$\Delta s \approx 334.545\,m$
