This is the answer 6x^2+15x+9
Average of the 2 years is (year1+year2)/2
year1=35000
year2=?average=37500
so
(year1+year2)/2=37500
(35000+?)/2=37500
times 2 both sides
35000+?=75000
minus 35000 both sides
?=40000
the profit in 2nd year must be $40,000
1 the cosine is > 0 is in the 4th quadrant if the sine is negative
