Answer:
First one - the root is in the bottom of the fraction (just like it is with trees) and she wrote it backwards. 2 to the four over three is the third root of two the power of four and not the other way around. Just change that and it's good.
Second one - he said that ln(2) = 2 and that's just not true. No way of fixing that one, he shouldn't get high as often as he does I guess.
Step-by-step explanation:
Answer:
(-2,-1)
Step-by-step explanation:
let the number=x
its reciprocal=1/x
x+2(1/x)=-3
x+2/x=-3
x²+2=-3x
x²+3x+2=0
(x+2)(x+1)=0
x=-2,-1
22 -22 = 0

Cost per passenger = C(t)/P(t) Derivative of C(t)/P(t) = (C'(t)P(t)-C(t)P'(t))/(P(t))² Rate of change at t=2 = (C'(2)P(2)-C(2)P'(2))/(P(2))²
