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:
It is a linear function, because the line has no curve, and the line is constant
Step-by-step explanation:
In a non linear function there would be a curve in the line, in this line there is no curve so therefore it is linear function.
Answer:
The slope of the line that is parallel to the given line is 
Step-by-step explanation:
Parallel lines have the same slopes and different y-intercepts
The slope of the line who has an equation ax + by = c is m =
Let us use these rules to solve the question
∵ The equation of a given line is 7x + 4y = -16
→ Compare it with the form of the equation above
∴ a = 7 and b = 4
∵ The slope of the line = 
∴ The slope of the line = 
∵ Parallel lines have the same slope
∴ The slope of the line that is parallel to the given line is 
Answer:
11
Step-by-step explanation:
15 - 4 = 11
