7 + 12 + 17 + 22 + 27 = ( 7 + 27 ) + ( 12 + 22 ) + ( 34 / 2 ) = ( 34 / 1 ) + ( 34 / 1 ) + ( 34 / 2 ) = ( 68 / 2 ) + ( 68 / 2 ) + ( 34 / 2 ) = 170 / 2 = 85 .
Answer:
B: (1,15)
Step-by-step explanation:
The points on the graph increase by 1 for the x-coordinates, and 15 for the y-coordinates.
A) is not a function because you have two X values of -1

Answer:
Work done
lb-ft
Step-by-step explanation:
The density of the chain in lb/ft is equal to
lb/ft
Total Work done is equal to the summation of work done up to the top of building.
We will use integration for this evaluation.
The mathematical relation is as follows

where "p" is the density
Substituting the given values, we get

Work done
lb-ft
It should be A, it’s the only answer that gives all the available choices or options he could get
