A manufacturing plant earned $80 per man-hour of labor when it opened. Each year, the plant earns an
additional 5% per man-hour.
Write a function that gives the amount Alt) that the plant earns per man-hour t years after it opens.
A(t) =

c

step-by-step explanation:

(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

a is the right answer
