Find the distance between (1,2) (-1,-2)
Helppp

2√5 ≈ 4.47214

Step-by-step explanation:

You can draw a triangle with corner points (-1,2); (1,2) and (-1,-2), and the distance will be the hypotenuse, use pythagoras to solve:

√(2²+4²) = √20 = 2√5

4.472 units

Step-by-step explanation:

1-(-1)=1+1=2

2-(-2)=2+2=4

2²+4²=c²

4+16=c²

20=c²

c=√20

c=4.472 units

part a

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
