For something to be a function, the input (x value) can ONLY HAVE ONE output (y value), so if x has multiple outputs, it is not a function

B is not a function because x = 2 and x = 9 has 2 outputs

Your answer is A

Answer:

Step-by-step explanation:

A represents a function. Why? Because all the x-values are unique (no duplications).

B does not represent a function. Why? Because the input 4 is repeated and has different y-values for this one input, and similarly the input 9 is repeated.

x = 13

Arc RQ = 180°

Step-by-step explanation:

PEQ is an inscribed angle and the measure of an inscribed angle in a circle is equal to half of the arc it sees.

The perimeter of a circle is always 360° therefore

2 × (5x + 15) + 9x + 17 + 6x - 12 = 25x + 35 = 360°

25x = 360 - 35

25x = 325

x = 13

Since arc RQ is equal to 10x + 30 we replace x with the value we just got

10×13 + 30 = 160°

Do you mean how you can get 16 in a multiplication problem? Then the answer would be 2 times 8 which would equal 16. Hope this helped.

Find the area of a circle whose circumference is 18.84.

ivann1987 [24]

Answer:

310.23

Step-by-step explanation:

circumference is radius * 2

to get radius from circumference, divide circumference by 2

18.84 / 2 =9.42

area for circle:

pi * r^2

3.14 * 9.94^2

3.14 * 98.8

310.23
