If you use Ruffini's method for polynomials, you can find the roots.

The given picture shows us the first root of the polynomial 5x^{2}-16x+12=0 wich is 2.

Thus, the original polynomial can be written as

(x-2)*(5x-6)=0

Here, you can notice that (x-2) is a factor

Without further study, you forget things as time passes. A model of human memory gives the percentage, p, of acquired knowledge
PIT_PIT [208]

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.
