What is the distance between nicholas's school and the post office?

aleksklad [387]

Part A:

Given that Nicholas's school is located at point (3, 2) and that the post office is located at point (-2, -2), then the distance between Nicholas's school and the post office is given by:

$d= \sqrt{(-2-3)^2+(-2-2)^2} \\ \\ = \sqrt{(-5)^2+(-4)^2} = \sqrt{25+16} \\ \\ \sqrt{41} =\bold{6.4} \ units$

Part B:

If Nicholas is located at point (– 3 , 2), the distance to get to the grocery store located at point (1,-1) is given by:

$d= \sqrt{(1-(-3))^2+(-1-2)^2} \\ \\ = \sqrt{(1+3)^2+(-3)^2} = \sqrt{(4)^2+9} \\ \\ = \sqrt{16+9} = \sqrt{25} =\bold{5}$

A farmer wishes to fence a rectangular area behind his barn. The barn forms one end of the rectangle and the length of the recta

Semenov [28]

1. The formula for calculate the perimeter of a rectangle, is:

P=2L+2W

P is the perimeter of the rectangle (P=320 feet).
L is the lenght of the rectangle.
W is the width of the rectangle.
<span>
2. The problem says that the length of the rectangle is three times the width, so you have:
</span>
L=3W

3. When you substitute L=3W and P=320, into P=2L+2W, you obtain:

P=2L+2W
320=2(3W)+2W
320=6W+2W
8W=320
W=320/8
W=40 feet

4. The barn forms one end of the rectangle. Therefore the linear feet of fence (x) is:

x=P-W
x=320 feet-40 feet
x=280 feet
<span>
How many linear feet of fence must he buy?
</span>
The answer is: 280 feet
