Mike is playing a video game. he tracks the number of points won in each round. in the first two rounds, he won 46 points. in the next 4 rounds, he won 35 points each. if x represents the round and y represents the points won in the round, which of the following describes the situation? a. neither a function nor a relation b. both a relation and a function c. a relation only d. a function only

B. both a relation and a function

Step-by-step explanation:

x = round number

y = points

lets make coordinate pairs

(1,46)

(2,46)

(3,46)

(4,46)

(5,46)

(6,46)

This is a relation since it is any set of ordered pairs

Is it a function?  It is a function if each input goes to only one output.  Each x goes to only one y so it is a function

B. both a relation and a function

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
