Step-by-step explanation:
The range is the set of the second values in the ordered pairs.
Answer:
Step-by-step explanation:
4y-4=10x+65, this can be expressed in many ways...
4y-10x-4-65=0
4y-10x-69=0 or
4y=10x+69
y=(10x+69)/4
The question is incomplete, here is the complete question:
Recall that m(t) = m.(1/2)^t/h for radioactive decay, where h is the half-life. Suppose that a 500 g sample of phosphorus-32 decays to 356 g over 7 days. Calculate the half life of the sample.
<u>Answer:</u> The half life of the sample of phosphorus-32 is 
<u>Step-by-step explanation:</u>
The equation used to calculate the half life of the sample is given as:

where,
m(t) = amount of sample after time 't' = 356 g
= initial amount of the sample = 500 g
t = time period = 7 days
h = half life of the sample = ?
Putting values in above equation, we get:

Hence, the half life of the sample of phosphorus-32 is
