Answer:

1. It increases at 0-15 minutes

2. The rate of change is 3 and I got it by using the formula; \frac{rise}{run} to calculate. So the line went up 15 and right 5 times so it'll be 15/5 = 3

3. It stays constant from 15-35 minutes.

4.The rate of change is 0 because the rate of change for every horizontal line is 0.

5. It decreases from 35-45 minutes

6. The rate of change is -4 and I got it by using the formula; \frac{rise}{run} to calculate. So the line went down -20 and right 5 times so it'll be -20/5 = -4

7. The rate of change is negative because the line is going down which means that the line is negative.

Step-by-step explanation:

1. As you can see the line is going up which means its increasing.

One of the parking lot lights at a hospital has a motion detector on it, and the equation (x+10)2+(y−8)2=16 describes the bounda
Pani-rosa [81]
We are given an equation:
(x+10)^{2} +  (y-8)^{2} = 16

This is an equation of a circle. General form of a circle equation is:
(x-a)^{2} + (y-b)^{2} = r^{2}
Where:
a = x coordinate of a center
b = y coordinate of a center
r = radius of a circle

Motion detector can detect person anywhere within a boundary. The greatest distance at which detector can detect is at the edge of a circle. That distance, between detector and edge of circle, is equal to radius.

From the equation we have:
r^{2} =16  \\ r=4
The greatest distance at which person can be detected is 4ft.

Helicopters can land on circular pads. The area of a landing pad is 1,962.5 square feet. What is the radius of the pad? Use 3.14
notsponge [240]

Answer:

25 ft

Step-by-step explanation:

The area of this landing pad is 1,962.5 ft², which equals πr².

We solve this equation for r²:

       1962.5 ft²

r² = -----------------  =  625 ft²

             3.14

Taking the square root of both sides, we get:

r = √(625 ft²) = 25 ft

The radius is 25 ft.
