Step-by-step explanation:
(-6+12i)-(7-19i)=
-6+12i-7+19i=
-13+31i
(b)
The general solution of <span>y' + 2xy = (x^3) is y(x) = c1e^(-x^2)
The general solution of </span><span>ydx = (y(e^y) - 2x)dy is x = c1/(y(x))^2 + (e^y(x) ((y(x))^2 - 2y(x) + 2)/(y(x))^2
</span>
The general solution of<span> (dP)/(dt) + 2tP = P + 4t - 2 is P(t) = c1e^(t - t^2) + 2</span>
Answer:880
Step-by-step explanation: They need to cover expense of $13200. If printing fee is $25 and they sell the books for $40 each, then that means when selling a book they cover expense of printing plus they earn $15 per book.
So if they earn $15 per book that means they have to sell 13200/15=880 books to break even.
If you want to solve this by using equation the this would look like this:
expenses: $13200 + $25x where x is number of books sold
earnings: $40x
Equation:
13200+25x=40x
13200=15x
x=880
D) 736
8 exams = 92.000
(8)x/8 = 92.000(8)
x = 736
