Remember that to tell if a function is linear for a table, you should look for a constant rate of change, and the only function that has a constant rate of change is the first one.

is increasing by 1, and

is increasing by 0.5.
Now that we know that, lets find the equation of our table.
First, lets take tow points from our table: (1,

) and

.
Next, use the slope formula:
We know for our points that

,

,

, and

, so lets replace those point in our formula to find

:


Finally, we can use the point slope formula

to find our equation:



We can conclude that the first table represents a linear function, and its equation is
1.5r+15=2.25r
Combine like terms: 1.5r+15-1.5r=2.25r-1.5r
15=0.75r
Get the unknown alone: 15/.75=.75/.75r
20=r or r=20 :)

The surface of interest can be parameterized by

with

and

.
The area of the surface

is given by the surface integral

We have

so the area is given by the double integral
Answer:

Step-by-step explanation:
Answer:
Approximately 4 loaves of bread.
Step-by-step explanation:
Let us get out the total amount of flour that Josh has first of all. This is
cups of flour.
Each lof requires
cups of flour. This means that to make a loaf, he will be taking out this quantity of flour from the whole lot.
To get the total number of loaves he can make with this quantity of flour, we will have to divide the total quantity of flour available by the quantity required to make a single loaf.
This will be
÷
=
. This is approximately 4 loaves of bread
