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.

25 apples to 10 oranges. What is the rate of the fruit

Klio2033 [76]

Answer:

The rate of the fruit is 5 apples to 2 oranges.

Step-by-step explanation:

The rate of the fruit is the ratio of apples to oranges. That is, the number of apples divided by the number of oranges into its simplest fraction form:

$x = \frac{25\,apples}{10\,oranges}$

$x = \frac{5\,apples}{2\,oranges}$

The rate of the fruit is 5 apples to 2 oranges.

How do i solve tan 6° = f/2.3

kondor19780726 [428]

Multiply both sides by 2.3, ( tan 6° x 2.3 = f )
Regroup terms, 2.3 tan 6 = f.
F = 2.3 tan 6°
So the answer is tan 6 = tan 6 I think
