Yes because 26 is an even number
Answer:
The number of calculators is 4871
Step-by-step explanation:
If we integrate dx/dt we get x, which is the number of calculators. To find the number of calculators between the beginning of third week to the end of fourth week (the beginning of fifth week), this integration must be evaluated at t between 3 and 5.

the result of the integration is:
to be evaluated between 3 and 5, which is:

The vertex to this quadratic equation is 2
Answer:

Step-by-step explanation:
Honestly not sure what all the numbers you put down were (numbers for the graph?), but here is how to find the slope :)
First, find two "exact" points!
I am going to use (0, 1) and (2, 2)
We then go to our first point, (0, 1), and count how many points up it is until we are on the same x-axis of our y. This is 1. We then do the same thing for the y-axis. This is 2. It is rise over run, so the answer is 
(I hope this helps, have a nice day!)
