Answer:
Increasing by 40%
Step-by-step explanation:
This is a exponentional function. The format for this type of function is a(b)^x. So "a" is your initial value, and "b" is the rate. Now let's think to ourselves what times what is still equal to the same thing? That is 1. But in our question, we have 1.4. So we are increasing by 0.4, or 40%.
The answer would be B. because a unit rate is usually equal to one for the sake of conversion
Answer:
where is your question ?????????
Answer:
It'll take 6.97 minutes to have only 1 package remaining.
Step-by-step explanation:
This problem can be interpreted as a compounded interest problem, where the initial amount is 172 packages the interest is 52% and the final amount is 1 package. The formula for compounded interest is:
M = C*(1 - r)^(t)
Where M is the final amount, C is the initial amount, r is the interest rate and t is time elapsed. So we have:
1 = 172*(1 - 0.52)^(t)
1 = 172*(0.48)^t
1/172 = 0.48^t
0.48^t = 0.006
log(0.48^t) = log(0.006)
t*log(0.48) = log(0.006)
-0.734*t = -5.116
t = 6.97
It'll take 6.97 minutes to have only 1 package remaining.
