The formula used for this is the same one used to find interest accrued in a bank account that compounds continuously. The only difference is that our r here, the rate, is a negative number because the carbon is deteriorating over time, whereas money grows over time. That formula is this one:
where A is what's left in the end, P is the initial amount of carbon, r is the rate at which it deteriorates (sometimes a k in other formulas, but same thing!) and t is the time in years. For us, that formula, filled in, looks like this:
First thing to do is to simplify that multiplication involving the exponents. Doing that gives us:
On your calculator, you have a 2nd button and an LN button. If you push 2nd and then LN you get this in your display:
and it's up to you to add the exponent on the e. Our exponent is the -.516. So do that and then multiply that result by 32 to get that your answer is 19.1 g of carbon remaining.
Answer:
-4/13
Step-by-step explanation:
just using your calculator and you can get the answer.
Given
12 meters tall airplane
18 meter shadow of airplane
6 meter shadow of jet
Find the measurement of the jet (y)
Solution
6y = 12 + 18 30
----- --------- ----> y = ------- -----------> y= 5
6 6 6
The answer is 5 meters tall is the measurement of a parked jet.
Answer:
3x + 2 = 5x -4
Step-by-step explanation:
The first condition is for the perimeter of the equation so:
Now the secon condition is that the sum of two sides should be:
so the negative option and 0 don't make sence dor a distance, then we try with the value of b=0.5
So in the first equation will be:
So the condition:
this is false, so the solution is
