Answer: 4 years
Step-by-step explanation:
A(0) has to be amount at start. Assume that's 5mg
Then A(t) = 5×(0.5)^(0.25t) = 5×2^(-t/4),
(also known as 5 exp(-λ t) with λ = ln(2)/4, incidentally).
We need to such that A(t) = 2.5mg, or 2^(-t/4) is 1/2, which happens when -t/4 is -1, or t is 4.
Answer:
See the attached
Step-by-step explanation:
The only function that shows x with an exponent of 1 is the one in the attachment. If the exponent is not 1, then the function is not linear.
(1/x = x^(-1))

Answer:
$ 75,673.89
Step-by-step explanation:
The formula for compounded interest is:

here A = total value in future
P= principal amount
r= annual interest rate
n= number of times interest is compounded
t= time (in years) the interest is compounded for
Plugging in values from the question we get:
250,000 = P * (1 + 0.1/12)^(12*12)
Solving for the principal amount (P) we get $ 75,673.89
