The number of people, y, at a party that remains after t hours can be modeled by the equation y= .75(.97)^t. What is the decreased rate of people at a party? A. 75% B. 25% C. 97% D. 3%

(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
