Which of the following is a geometric sequence? a
3, 6, 9, 12, … b
11, 15, 19, 23, … c
4, -16, 64, -256, … d
50, 25, 0, -25, …

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

practice. practice. practice.

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:

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
