What is the formula for this question?

2.7

Step-by-step explanation:

This can be modeled using exponential growth/decay.

A = P (1 + r)ⁿ

where A is the final amount,

P is the initial amount,

r is the rate of growth/decay,

and n is the number of cycles.

For half life problems, r = -½, and n = t / T, where t is time and T is the half life.

A = P (1 − ½)^(t/T)

A = P (½)^(t/T)

Given that P = 9, t = 10000, and T = 5730:

A = 9 (½)^(10000/5730)

A ≈ 2.7

There are approximately 2.7 mg of ¹⁴C left.

1st part is 64,000,000

2nd part 500,000

step-by-step explanation:

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
