This symbol means that you have to evaluate the generic term at n=1,2,3,4,5, and then sum all the terms. Here's the table:
So, their sum is
Alternatively, you manipulate the expression to get
For the first sum you can use the formula
The second sum is simply 1 summed 5 times with itself: 1+1+1+1+1=5.
So, we have
The tangent line to the curve has slope equal to at the point (2, -1). We have, by implicit differentiation,
At the point (2, -1), the slope is then 2/9, so the tangent line has equation
Since .7 is in the tens place you would put 70 0ver 100 as 70/100 which in percent would be = 70%
