Find the height of each pyramid: square pyramid: volume 225 cubic inches, base edge 5 inches.

The height of the pyramid is

Step-by-step explanation:

we know that

The volume of the square pyramid is equal to

where

B is the area of the square base of the pyramid

h is the height of the pyramid

Find the area of the base B

-----> is a square

we have

substitute the values in the formula and solve for h

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.
