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:

where a and b are constants.

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

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


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