Answer 1

1) f(p) = 4/p;  g(p) =(p - 2)/3

(f o p) = 4/(p - 2)/3 = 4x3/(p - 2) = 12/p - 2

2.) I(u) = (1000 - 2U).U = 1000U - 2U²

I(100) = 1000(100) - 2(100²) = 100000 - 20000 = 80000

3.) 
  g(x) = 4x + 3

f(g(x)) =

4.) G(t) = 40 - 2t:

G - 40 = -2t

-G/2 - (40/-2) = t

20 - (G/2) = t

5.)
 




(f+g)(2)









(f+g)(2)= \frac{4\sqrt{1}+4\sqrt{1}+2}{4}



(f+g)(2) = 10/4 = 5/2

6.)


Y(X + 100) = [5000X/(X+100)](X+100)

Y(X + 100) = 5000X

Y(X) + Y(100) = 5000X

5000X = YX + 100Y

5000X - YX = 100Y

-X(Y - 5000) = 100Y

X = 100Y/-(Y -5000)

X = -100Y/(Y - 5000)

X = Y

Y = -100X/(Y - 5000)
