If t = 0, this would indicate that no time has passed and therefore no visitors have since visited the website. (10,600 • 2(0) = 0)
if t = -2, this would indicate that this is how many visitors there were in comparison to 2 months ago, which is why the number is negative to indicate that there were less visitors two months prior compared to now (10,600 • 2(-2) = -42,400)
100 % + 5.6=105.6 / 100= 1.056 so you do 1234x 1.056to the power of 7 because it is 7 years so the answer is 1807 pounds
Answer:
3.12 kg.
Step-by-step explanation:
Mass after t years:
The mass of the elements after t years is given by the following equation:
In which M(0) is the initial mass and r is the decay rate, as a decimal.
The half life of Cs-137 is 30.2 years.
This means that:
We use this to find r.
So
If the initial mass of the sample is 100kg, how much will remain after 151 years?
This is M(151), with M(0) = 100. So
The answer is 3.12 kg.
If you have two equations, you will multiply one of them so it cancels out the other one. For Example, 2x-y=16 3x-y=28You will multiply the second equation by -1 which brings us to 2x-y=16 -3x+y=-28you will add both equations together which will leave you with-x=-12x=12Then, you plug that in. 2x12=24. 24-16=8. 3x12=36 36-8=28 And, You're done!
