The value of a car purchased for $20,000 decreases at a rate of 12% per year. what will be the value of the car after 3 years?

$13,629.44

Step-by-step explanation:

Value of car after 3 years is:

V = $20,000(1.00-0.12)^3, or

      $20,000(0.88)^3 = $13,629.44

(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

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
