Calculate one third of the sum of 23 and the square of 5
The sum of 32 is 9.
Calculate the sum
Three ways.. Multiply n by itself. Calculate Sum[2i+1,{i,0,n-1}] Calculate Sum[n,{i,1,n}]
A third of the sum. One-third of nine would be three, for instance.
1/2*(sum of parallel bases)*height = area
one divided by three gives one third.
five-sixths
32 and two-thirds
In general, you divide up the polygon into triangles, calculate the areas of the triangles and then sum these.
If you have a data set, simply take the square root of the sum of the squares of the data points. Let's say you have three numbers a, b, and c. RSS = SQRT(a2 + b2 + c2).
Magnitude of the resultant vector = Square root of[ (sum of x-components of all component vectors)2 plus(sum of y-components of all component vectors)2plus (sum of z-components of all component vectors)2 ]
