A particular sound wave can be graphed using the function y = -1 sin 5x. Find the period of the function. (This is multiple choice.)

period =2/5pie
o
period = 1
O
period = -1

period 2/5

the third answer is correct

(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
