What is 20 persent of 10?

2

Step-by-step explanation:

Turn your percent into a decimal.

20% = 0.2

Your question was: What is 20 percent of 10?

When seeing the word OF you know that you're going to be multiplying.

10 times 0.2

10 x 0.2 = 2

Your answer is 2

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:

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
