Radioactive technetium-99m is often used in diagnostic medicine because it has relatively short half-life but lasts long enough to get the needed testing done on the patient. If its half-life is 6 hours, how much of the radioactive material from a 0.5ml injection will be in the body in 24 hours? Write your answer rounded to nearest hundredth.

the answer is 62

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

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

3       6.8

step-by-step explanation:

c - they will have the same distribution
