Given right triangle ABCABC with altitude \overline{BD} BD drawn to hypotenuse ACAC. If AB=4AB=4 and AD=1,AD=1, what is the length of \overline{AC}? AC ? (Note: the figure is not drawn to scale.)

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

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

x       y

0       8

1       7.6

2       7.2
