Answer:
A is f ", B is f, C is f '.
Step-by-step explanation:
Your answer is correct. B is the original function f. It has a local maximum at x=0, and local minimums at approximately x=-3/2 and x=3/2.
C is the first derivative. It crosses the x-axis at each place where B is a min or max. C itself has a local maximum at approximately x=-3/4 and a local minimum at approximately x=3/4.
Finally, A is the second derivative. It crosses the x-axis at each place where C is a min or max.
THE CORRECT ANSWER IS N=4
Answer:
D
Step-by-step explanation:
-9x-27+12 = -6x-15-3x
0=0
D) the equation has infinitely many solutions
Fixed price costs
Crew salaries 350
fuel 120
overheads 170
Total fixed cost: 640
Variable costs per passenger
refreshments $ 6.50
refund $ 3.64
total variable cost: 10.14
Sales income
<span>Average ticket $ 36 .40
</span><span>Break-even point = <u> (fixed costs) </u>
(income per passenger – costs per passenger) </span><span>
</span>
Break even = 640 / (36.40-10.14) = 640 / 26.26 = 24.37
48 is the answer you will get
