For this case we have the following quadratic functions:
Revenue: ![3x ^ 2 + 4x - 60](https://tex.z-dn.net/?f=%203x%20%5E%202%20%2B%204x%20-%2060%20%20)
Cost: ![3x ^ 2 - x + 200](https://tex.z-dn.net/?f=%203x%20%5E%202%20-%20x%20%2B%20200%20%20)
Then, we observe that the profit is given by the following mathematical relationship:
![Profit = Revenue - Cost](https://tex.z-dn.net/?f=%20Profit%20%3D%20Revenue%20-%20Cost%20%20)
Substituting values we have:
![Profit = (3x ^ 2 + 4x - 60) - (3x ^ 2 - x + 200)](https://tex.z-dn.net/?f=%20Profit%20%3D%20%283x%20%5E%202%20%2B%204x%20-%2060%29%20-%20%283x%20%5E%202%20-%20x%20%2B%20200%29%20%20)
Making the corresponding calculations we have:
![Profit = x ^ 2 (3-3) + x (4 + 1) + (-60-200)\\Profit = 5x - 260](https://tex.z-dn.net/?f=%20Profit%20%3D%20x%20%5E%202%20%283-3%29%20%2B%20x%20%284%20%2B%201%29%20%2B%20%28-60-200%29%5C%5CProfit%20%3D%205x%20-%20260%20%20)
Answer:
An expression that represents the profit is:
![Profit = 5x - 260](https://tex.z-dn.net/?f=%20Profit%20%3D%205x%20-%20260%20)
Answer:
Weakest value = 0.0196
Strongest value = 0.5929
Step-by-step explanation:
Given:
Choices
0.691
-0.14
-0.24
-0.77
Computation:
0.691² = 0.477481
-0.14² = 0.0196
-0.24² = 0.0576
-0.77² = 0.5929
Weakest value = 0.0196
Strongest value = 0.5929
6+5=11+5=16+5=21
3+6=9+6=15+6=21
It will take Marco and Sophie 3 hours to get the same amount of money. The amount of money they will have will be $21.
(i just changed my answer)
sqrt is the square root of
v=sqrt(2(ke)/m)
X is the undefined variable hope it helps
