A police officer seals off the scene of an accident using a roll of yellow tape that is 272 feet long. What dimensions should be
klasskru [66]

Answer:

  68 feet square

Step-by-step explanation:

The rectangle with the maximum area for a given perimeter is a square. The perimeter of a square is 4 times the side length, so the side length of the square area will be ...

  (272 ft)/4 = 68 ft

_____

<em>More formally ...</em>

You can let x represent the length of one side. Then the length of the other side for the given perimeter will be 136 -x, and the area will be the product ...

  area = x(136 -x)

The area function is a quadratic with zeros at x=0 and x=136. The vertex (maximum area) will be at the value of x that is on the line of symmetry between these points, at their midpoint: x = (0 +136)/2 = 68. This value of x makes the rectangle a square.

| -6x - 3 | > 15

This expression can be written as:

a) -6x - 3 > 15 
b) -15 > - 6x - 3

Solving a part:

- 6x - 3 \ \textgreater \  15 \\  \\ &#10;- 6x \ \textgreater \  18 \\  \\ &#10;x \ \textless \  -3

Solving b part:

-15 \ \textgreater \  - 6x - 3 \\  \\ &#10;-12 \ \textgreater \  - 6x \\  \\ &#10;2 \ \textless \  x

or we can write:
x > 2

So the solution to given inequality is:
x \ \textless \  -3  \\ or  \\ x \ \textgreater \  2

The second option correctly lists this solution.

Question in image please help quickly, I'm on a time limit :D
inn [45]

Answer:

By distance formula ,

AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

AB = \sqrt{(-1-5)^2 + (6-3)^2}

AB = \sqrt{36 + 9}

AB = \sqrt{45}

AB = 6.708(approx)

To give answer in 3 significant figures :

AB = 6.70
