Answer:
- $2300000- max profit
- 5.77 years into operation - zero profit time
Step-by-step explanation:
<u>Given function:</u>
It is a quadratic function with general form of y = ax^2 + bx + c
It opens down if a < 0 and gets maximum value at vertex which is determined at x = -b/2a
<u>For the given function vertex is:</u>
<u>Maximum value of p is:</u>
- p(3) = -3*3^2 + 18*3 - 4 = -27 + 54 - 4 = 23 ($2300000)
<u>The time when profit is zero:</u>
- -3t^2 + 18t - 4 = 0
- 3t^2 - 18t + 4 = 0
- t = (18 ± √18² - 4*3*4)/2*3 = (18 ± √276)/6 = (18 ± 16.61)/6
- t = (18 - 16.61)/6 = 0.23 this is the time when company has just started to make profit, it is not applicable as is the past time
- t = (18 + 16.61)/6 = 5.77 years into operation, after this time there will be no profit
The answer is zero (0), when you add any number to it's opposite you always get zero
Is this asking? Also does this have answer choices?
Answer:
i found that the bag is 132 cubed and the candle is 117.81 and 132 cubed - 117.81 is =2299850.19 so im pretty sure thats the answer for b
Step-by-step explanation:
but for c if its 1 bag per teacher (like i think it is) then i multiplied 2299850.19 by 70 and i got = 160989513.3
-i dont know for sure if this is correct (tbh im kinda confused) but i hope this helped have a good rest of your day :)
