Answer
7.21
Step-by-step explanation:
Data :
(-3,-4) , (1,2)
Where
x₁ = -3 , x₂ = 1
y₁ = -4 , y₂ = 2
Formula for distance
D = √{(x₂-x₁)² + (y₂-y₁)²}
= √{(l--3)² + (2--4)²} = √(16+36) =√52 =7.21

Jamal wants to build a rectangular enclosure for his animals. One side of the pen will be against the barn, so he needs no fence
den301095 [7]

Answer:

Area of the rectangle = 700 - 2w²

Step-by-step explanation:

In the picture attached one side of the rectangle is Barn.

Two perpendicular sides of the barn are width 'w' and one parallel side to the barn is 'l'.

Jamal has the fencing having length = 700 feet

So, to cover three sides of the rectangle length of wire required = (2w + l) feet

This length should be equal to the length of the wire, which is to be used to cover these three sides.

(2w + l) = 700

l = 700 - 2w ------(1)

Area of the rectangle = lw

By replacing the value of l from equation 1

Area = w(700 - 2w)

Area = 700w - 2w²

Jan left her home and drove for 5.2 hours due north at a rate of 60 miles per hour. After visiting a friend, she drove due south
Andreyy89

Answer:

180 miles

Step-by-step explanation:

Going North

<em><u>Formula</u></em>

d = r * t

<em><u>Givens</u></em>

r = 60 mph

t = 5.2 hours

d = ?

<em><u>Solution</u></em>

d = 5.2 * 60 = 312 miles north

Going South

<em><u>Givens</u></em>

r = 55 mph

t = 2.4 hours

<em><u>Solution</u></em>

d = r * t

d = 55 * 2.4

d = 132

Distance from home

Formula: Distance from home = Distance North - Distance South

Distance North = 312  -   132 = 180 miles
