Answer:
The sample would double in 9 hours
Step-by-step explanation
The number of hours it will take for the sample to double can be found using the 72 rule.
The 72 rule is such that a growth rate would double itself by it is used in dividing the number 72 as shown below:
number of hours =72/8=9 hours
The number of hours it would take the sample to double is 9 hours as computed above.
Answer:
7 years
Step-by-step explanation:
Because there is no graph, I will just tell you how many years it should take, and you can probably figure it out from there. To start, let's [get out a calculator] find out what 2% of 250 is. This is 5, so we can add 5. Notice that adding 5 to the number does not change 2% of it by much, only by 5/50 or 0.1. So, we can keep adding until we get above 282, which should take 285 minus 250 over 5 times, or 7. So, the answer is 7 years. You can [get out a calculator] and find out that it is indeed 7 years.
Answer:

The graphing calculator also has functions to find where the graphs intersect between two points and are accurate sometimes to ten decimal places. When compared to graphing by hand you can get inaccurate results and results that are not as precise.</span></span>
