A sample of radioactive trillium disintegrates to m=200e^-0.0577t, where m is the mass (in grams) of remaining radioactive tritium after t years. Find the initial amount of radioactive tritium.

Step-by-step explanation:

The initial amount is the constant in the given equation:

It can also be found by substitution of t with 0 in the given equation. We know any exponent with the power of zero equals to 1.

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
