Answer: y = 122.5
Step-by-step explanation:
A relation is (also) a function if every input x is mapped to a unique output y.
In terms of graphical representation, this implies that a graph represents a function if there doesn't exist a vertical line that intersects the graph more than once. So:
- The first graph is exactly a vertical line, so it's not a function.
- The second graph represents the function y=x, so it's a function: you can see that every possible vertical line crosses the graph only once.
- The third graph is not a function, because you can draw vertical lines that cross the graph twice.
- Similarly, in the fourth graph you can draw vertical lines that cross the graph twice
- The fifth graph is a function, because every vertical line crosses the graph once
- The last graph is a function, although discontinuous, for the same reason.
Answer:
Step-by-step explanation:
I'm not sure what T represents, but it must have something to do with pi
V/T = r * h Now divide by r
V/(Tr) =h
Answer:
2x^2-9x-5
Step-by-step explanation:
Just multiply
The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base. The general formula for the lateral surface area of a regular pyramid is L . S . A . = 1 2 p l where represents the perimeter of the base and the slant height.
