Without further study, you forget things as time passes. A model of human memory gives the percentage, p, of acquired knowledge

that a person retains after t weeks. The formula is p = (100 – a)e-bt + a, where a and b vary from one person to another. If a = 18 and b = 0.6 for a certain student, how much information will the student retain two weeks after learning it?

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

where a and b are constants.

a = 18\\b = 0.6

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

Thus, 42.69% of information is acquired by the student in two weeks.
