Which of the following relations are functions? {(0,1), (0,2), (5,2), (-5,2), (5,7)}
O {(-3,2), (-2,2), (1,2), (-3,1), (0,3)}
{(-1,6), (-2,8), (-1,2), (-5,1), (0,6)}
{(-2, 6), (2,0), (3,6), (4.-1), (5. 3)}

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
