Determine which gym's membership grows faster from Month 2 to Month 4 by calculating the average rates of change.

Gym A is growing faster

Gym A gained 13 members between months 2 and 4

Gym B gained 10 members between months 2 and 4

Step-by-step explanation:

Gym A:  (2,20) (4,46)

rate of change = (46-20)/(4-2)  =  26/2 or 13

Gym B:  (2,40) (4,60)

rate of change = (60-40)/(4-2)  =  20/2 or 10

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
