Answer:
E: (2, -1)
F: (3, -1)
G: (3, -2)
H: (2, -2)
Step-by-step explanation:
Reflect all coordinates over an x-axis
Because you are reflection 180 degrees over the x axis, the y-axis is going to stay the same (because you are not moving the square left or right. When reflecting over axis always add the same amount you took away from the other side, if that makes any sense.
Answer:
46 minutes
Step-by-step explanation:
Sorry about not answering your question sooner, but here is your answer:
In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left ver after the call:
15 - 6.72 = 8.28
Then, we divide this number by 0.18:
8.28 / 0.18 = 46
So, Tammy's call lasted 46 minutes
Hope this helps :)
Answer:
The monopolist's net profit function would be:
![N(y)=198\,y\,-\,2.5\,y^2](https://tex.z-dn.net/?f=N%28y%29%3D198%5C%2Cy%5C%2C-%5C%2C2.5%5C%2Cy%5E2)
Step-by-step explanation:
Recall that perfect price discrimination means that the monopolist would be able to get the maximum price that consumers are willing to pay for his products.
Therefore, if the demand curve is given by the function:
![P(y)=200-2y](https://tex.z-dn.net/?f=P%28y%29%3D200-2y)
P stands for the price the consumers are willing to pay for the commodity and "y" stands for the quantity of units demanded at that price.
Then, the total income function (I) for the monopolist would be the product of the price the customers are willing to pay (that is function P) times the number of units that are sold at that price (y):
![I(y)=y*P(y)\\I(y)=y\,(200-2y)\\I(y)= 200y-2y^2](https://tex.z-dn.net/?f=I%28y%29%3Dy%2AP%28y%29%5C%5CI%28y%29%3Dy%5C%2C%28200-2y%29%5C%5CI%28y%29%3D%20200y-2y%5E2)
Therefore, the net profit (N) for the monopolist would be the difference between the Income and Cost functions (Income minus Cost):
![N(y)=I(y)-C(y)\\N(y)=(200\,y-2y^2)-(2y+0.5y^2)\\N(y)=198\,y\,-\,2.5\,y^2](https://tex.z-dn.net/?f=N%28y%29%3DI%28y%29-C%28y%29%5C%5CN%28y%29%3D%28200%5C%2Cy-2y%5E2%29-%282y%2B0.5y%5E2%29%5C%5CN%28y%29%3D198%5C%2Cy%5C%2C-%5C%2C2.5%5C%2Cy%5E2)
999.999 because if one is 99 the other would make it 9999
