Step-by-step explanation:
The area <em>A</em> under the curve can be written as

To evaluate the integral, let

so the integral becomes

or

Putting in the limits of integration, our area becomes

![\;\;\;\;= \frac{1}{2}[\ln (1+16) - \ln (1)]](https://tex.z-dn.net/?f=%5C%3B%5C%3B%5C%3B%5C%3B%3D%20%5Cfrac%7B1%7D%7B2%7D%5B%5Cln%20%281%2B16%29%20-%20%5Cln%20%281%29%5D)

Note: 
Answer:
The correct answer is - 17.
Step-by-step explanation:
Given:
total students = 219
in chemistry = 112
in physics = 45
not enrolled in either of these = 79
solution:
The number of students in both classes can be calculated by
P ( A or B) = P (A) + P (B) - P (A and B)
then putting and solving the given vaues in formula
=> (219-79) = 112+45-x
=> 140 = 157 -x
=> 17 = x
You use it at the end of a sentence and it looks like this! It means like loud
