Answer:

...

Step-by-step explanation:

di = 2.5 -( - 1.5) = 4

radius = di/2 = 2

c(x, y) =( - 0.5 , 2.5-0.5) =(-0.5 , 0.5)

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.

Factor out the greatest common factor of Given the expression: 4x^10 − 64x^2<br><br>

Alexxandr [17]

Part A

4x10 – 64x2

= 4x2 * x8 – 4x2 * 16

= 4x2 * (x8 – 16) by distributive property

Part B

x8 is (x4)2 and 16 = 42 so a difference of squares is seen in the parentheses. The pattern a2 – b2 = (a + b)(a – b) can be used.

4x2 * (x8 – 16)

= 4x2 * (x4 + 4) * (x4 – 4)

x4 = (x2)2 and 4 = 22 so there is another difference of squares in the last factor. Use the pattern again.

= 4x2 * (x4 + 4) * (x2 + 2) * (x2 – 2)

The glass fish tank does not have a cover. Find the total area of the glass panels used to make the tank.

pogonyaev

You will find the area of the 5 surfaces made of glass. There is a front, back, 2 sides, and the bottom. Each face is in the shape of a rectangle, so you will multiply the length by the width.
1. Front- 24 x 27 =648
Back-24 x 27 = 648
2. Side- 21 x 27 =567
Side - 21 x 27 = 567
3. Bottom - 21 x 24 = 504

Add all these together for your total amount of glass needed. The answer is 2934 square cm of glass.

Answer:

Step-by-step explanation:

Since 15 tamales is $10, you can take 10/15 to get the price of one tamale, 0.67. Since you know the price of one tamale now, you can multiply 0.67*36 to get that 36 tamales is equal to $24
