Answer:
Applying the Pythagorean theorem, the diagonal is calculated by:
D = sqrt(40^2 + 9^2) = 41
Hope this helps!

The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is 
or:
Example:
Let's say you're give this table:
x: 1, 2
y: 1, 2
Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1
Do the same for x
Now plug the values taken in the slope formula and you get:
Therefore the slope is 1.
Answer:
The answer to your question is $56
Step-by-step explanation:
Data
Payment before noon = $11.20
Payment after noon = $11.20/2
Time from 9:00 to 16:00
Process
1.- Calculate the hours worked before noon and the hours worked after noon.
Before noon = 12:00 - 9 = 3 hours
After noon = 16:00 - 12:00 = 4 hours
2.- Calculate the payment
Payment = (3 x 11.2) + (4 x 11.2/2)
= 33.6 + 22.4
= $56
