Three security cameras were mounted at the corners of a triangular parking lot. Camera 1 was 106 ft from camera 2, which was 133

Harrizon [31]

Correct Answer:
Option C. Camera 2

The greatest angle is always opposite to the side measure greater in length. So first we find the greatest side.

The distance between cameras is:

Camera 1 and Camera 2 : 106 feet
Camera 2 and Camera 3 : 133 feet
Camera 1 and Camera 3 : 151 feet

So the largest side of the triangle is the side between camera 1 and camera 3. So the camera opposite to this side will have to cover to greatest angle. The camera opposite to this side is Camera 2. This scenario is also shown in figure below.

Therefore, Camera 2 had to cover the greatest angle.

Find the consecutive even integers such that their sum is equal to the difference of three times the larger and two times the sm

Digiron [165]

Let the integers be x and x + 2, then
x + x + 2 = 3(x + 2) - 2x
2x + 2 = 3x + 6 - 2x
2x + 2 = x + 6
2x - x = 6 - 2
x = 4

Therefore, the integers are 4 and 6

The temperature on a particular day started at –13°F. It rose steadily by 3° each hour. The function y = –13 + 3x models the tem

alex41 [277]

The function you're given is in point-slope format, which is one of the easiest ones to graph. The basic form of the format is;

y=ax+b

Where a is the slope and b is the y-intercept.

As you can see, in y=-13+3x, the positions of a and b are switched, but it is essentially the same question.

From here we can tell that the y-intercept is -13, meaning that there is a point on the line that rests at (0,-13)

To find the other points, we can do rise-over-run using the slope of 3 given to us. What happens here is that for every 1 unit you go to the right (positive), you rise 3 units up.

For example, if we perform this on the y-intercept (0,-13):

(0+1, -13+3)
(1,-10)

With these two points, you can graph the line representing the temperature.
