Answer:

y = $\frac{5}{2}$ x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = $\frac{5}{2}$ , thus

y = $\frac{5}{2}$ x + c ← is the partial equation

To find c substitute (- 2, - 1) into the partial equation

- 1 = - 5 + c ⇒ c = - 1 + 5 = 4

y = $\frac{5}{2}$ x + 4 ← equation of line

An earthquake was felt throughout a circular area of 1,808.64 square miles. What was the radius of the circular area?

spin [16.1K]

A. 24 miles

Explanation:

the area inside a circle is given by:

$A=\pi r^2$

where r is the radius of the circle.

In this problem, we know the circular area:

$A=1,808.64 mi^2$

So we can re-arrange the equation above to find r, the radius:

$r=\sqrt{\frac{A}{\pi}}=\sqrt{\frac{1,808.64}{\pi}}=24.0 mi$

so, the radius of the circular area is 24 miles.

What is the slope of the line that passes through the points (2, 2), and (4,2)

vfiekz [6]

Answer:

There is no slope. $m=0$

Step-by-step explanation:

$m=\frac{rise}{run}=\frac{2-2}{4-2}=\frac{0}{2}=0$

(2, 2) and (4,2) makes a horizontal line. All horizontal lines on a graph have no slope.

Find the height of the triangle

Paul [167]

There are two -main- approaches to answer this problem. By using the sine identity, or applying law of sines.

We'll do the sine trig. identity, as it is the most effective.

Given an angle ' $\alpha$ ' in a right triangle, ' $sin( \alpha )$ ' is defined as the opposite side of the triangle to the given angle, over the triangle's hypotenuse.

So, for this setup:
$sin(20)= \frac{x}{10}$

Now, we solve for x:
$x=10sin(20)=3.42$

So, answer is 3.4

a car covered a certain distance at the speed of 24mph. while returning, the car covered he same distance witht eh spped of 16mp

Mkey [24]

Answer:

19.2

Step-by-step explanation:

You have to trust me, this answer is correct. But here's my solution:

With the formula

Distance=Speed multiplied by Time, we can infer that Speed=Distance/Time.

But we only have one variable (Speed) in the two we need (Speed and Time), we have to pretend we have both variables. You can put the time as 1 hour because that's the most basic unit. Note that this strategy will also work with 2 hours, 3 hours, or any measure of time.

So now for distance, let's see how fast a car can travel 24 miles. When going at 24 mph, then it'll take 1 hour. With 16 mph, then it'll take 1 hour and 30 minutes, so 1.5 or 3/2 hours.

Now we have the distance, which is 2 times 24 (Because the 24 mph and 16 mph both traveled 24 miles), equaling 48, and time, which is 1 hour plus 1.5 hours, which is 2.5 hours.

Now we use the formula Speed=Distance/Time, with 48/2.5=19 1/5 or 19.2
