What is the surface area of the regular pyramid below?

the answer is A :960 sq units

Step-by-step explanation:

because the triangles are (16x22=352) but i have to divide them by 1/2 so it would be 4 176 and that equals 704 then u have to do the bottom(16x16=256)

so 704+256=960

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.

step-by-step explanation:

not sure but it may be b, as i said i'm not sure.
