Arectangular prism's base is 8 feet long. it is 2 1/2 times taller then it is long and 1/2 as wide as it is tall. what is the volume of the prism?

The volume is 640 ft3.

To find a volume of a rectangular prism is:

Length: 8 feet

Width:

Height:

Plug in the values and solve:

answer:

c. the third graph

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
