For f(x)=2x+1 and g(x)=x^2-7, find (f/g)(x)
2 answers:
The question is asking us to divide the function f(x) by the function g(x).
Knowing this, we can perform the division:
(2x+1)/(x^2-7) = (f/g)(x)
The simplest answer is
, as there is no way to further simplify the problem. This means that there is a discontinuity where 
, as it is impossible to divide by 0.
Knowing this, we can perform the division:
(2x+1)/(x^2-7) = (f/g)(x)
The simplest answer is

Answer: 0.5
Step-by-step explanation:
Given : Adult male heights have a normal probability distribution .
Population mean :
Standard deviation:
Let x be the random variable that represent the heights of adult male.
z-score :
For x=70, we have
Now, by using the standard normal distribution table, we have
The probability that a randomly selected male is more than 70 inches tall :-
Hence, the probability that a randomly selected male is more than 70 inches tall = 0.5
Since m is the midpoint of ab, then the following relationship is fulfilled:
Therefore, substituting values we have:
From here, we clear the value of x.
We have then:
Then, the value of am, is given by substituting x in the expression:
Substituting we have:
Answer:
the length of am is:
Therefore, substituting values we have:
From here, we clear the value of x.
We have then:
Then, the value of am, is given by substituting x in the expression:
Substituting we have:
Answer:
the length of am is:
