I got 441 times using this formula 7x3^2=x
First multiply the power, 3 x -2 = -6
Thus, 5^-6
Make the power positive
1/5^6
1/15625

Answer:
42.69% of information is acquired by the student in two weeks.
Step-by-step explanation:
We are given the following in the question:
![p = (100 -a)e^{-bt} + a](https://tex.z-dn.net/?f=p%20%3D%20%28100%20-a%29e%5E%7B-bt%7D%20%2B%20a)
where a and b are constants.
![a = 18\\b = 0.6](https://tex.z-dn.net/?f=a%20%3D%2018%5C%5Cb%20%3D%200.6)
p tells us about the percentage of acquired knowledge that a person retains after t weeks.
We have to find the percentage of knowledge acquired in two week.
We put t = 2
![p = (100 -18)e^{-(0.6)(2)} + 18\\p = 42.69](https://tex.z-dn.net/?f=p%20%3D%20%28100%20-18%29e%5E%7B-%280.6%29%282%29%7D%20%2B%2018%5C%5Cp%20%3D%2042.69)
Thus, 42.69% of information is acquired by the student in two weeks.
