Remark
When you take the limit of

the odd result you get is 1. Later on you will be able to use calculus to show this. For now just take limits of sin(x)/x and make sure you are feeding radians into your calculator.
Now the only question is what is this thing doing?
If a is a constant in

then the result = a.
So that's basically all you need to know to solve your problem.
Series
Each term in the series will be
a*(sin(ax)/x) = a * [sin(ax)/x] * 1 = a * a = a^2
The series will look like this.
1 + 4 + 9 + 16 + 25 + 36 + 49 + 64 + 81 + 100 There is a way of summing this using n notation, but you could just as easily just add the results.
<span>
The formula for this series (if you want a sum) is n*(n+1)*(2n+1) / 6
</span>n = 10
Sum = 10*(11)(21)/6
Sum = 385
Does adding it by hand bring up 385?
Answer:
3 1/6
Step-by-step explanation:
19/6= 3.1666666666666 also known as 3 1/6
check your work by multiplying 3 1/6 by 6 and get 19

Answer:
They provide you with a graph that already has all the numbers and there is a data table. The data table lists all the numbers you have to plot onto the graph.
How to graph: The first number is 27, which is the vehicle weight in hundreds of lbs. On the graph, you can see that on the x-axis, it says weight (in hundreds of lbs). So first, look at the x-axis numbers and find somewhere between 25 and 30 and try to estimate where 27 would be.
Now look at the city MPG value that corresponds to 27, the weight value. It is 25. That's perfect because it is exactly the intervals the graph is in. So find 25 on the y-axis since the y-axis represents the city MPG. Now draw a straight line from the 25 on the y axis to the right. Then, draw a line from the 27 on the x axis straight up and where the two meet is the first point. Obviously, you don't need to make it that complicated if you don't need all the extra steps to understand but it is just in case you don't know how to graph the points.
Repeat for the rest of the points (make sure you use the correct corresponding points). Good luck on your test!
