Consider a monopolist whose total cost function is TC = 20 + 10Q + 0.3Q2 and whose marginal cost function is MC = 10 + 0.6Q. The demand function for the firm’s good is P = 120 - 0.2Q. The firm optimizes by producing the level of output that maximizes profit or minimizes loss. If the firm uses a uniform pricing strategy, then the firm will:

A) produce 90 units of output, charge a price of $102, and earn a profit of $9180

B) produce 90 units of output, charge a price of $102, and earn a profit of $7460

C) produce 110 units of output, charge a price of $98, and earn a profit of $6030

D) produce 110 units of output, charge a price of $98, and earn a profit of $10780

Consider a monopolist whose total cost function is TC = 40 + 4Q + Q2 and whose marginal cost function is MC = 4 + 2Q. The demand function for the firm’s good is P = 160 - 0.5Q. The firm optimizes by producing the level of output that maximizes profit or minimizes loss. If the firm uses a uniform pricing strategy, then the price elasticity of demand (ED) at the profit maximizing price is equal to:

A) 0.5

B) 1.0

C) 2.6

D) 4.5

E) 5.2

Tan pi/6 - sin pi/3 can you explain how you got the answer please

How do you subtract the tangent of pi over 6 from sine of pi over 3 sooo in other words

Tan pi/3 - sin pi/3 ?!?!?! Please help me and explain how you got your answer.

Also how do you do cosecant of 60 degrees- sine of 45 degrees?! Please explain this answer to me as well. Im so lost.

Two busses leave houston at the same time and travel in opposite directions. One bus averages 55 mi/h and the other averages 45mi/h. When will they be 400 miles apart?

Ok, so I just got my Ipod Touch 4th Generation today. I plugged it up to the computer and started downloading apps. And fixing it the way I like it. But then I was checking out one of the apps and the Ipod froze and said I need to force quit the app Idk. So I went back to it and it was being retarded so I exited out of it all together. And I went to one of my textfree apps apps and it froze again. And now all I see is a white screen. Even if I plug it up to the computer it works perfectly fine but I cant see the Ipod screen. Ive tried resetting it and it doesnt work. Can someone please help me. I just got it and really dont wanna return it and wait a whole week AGAIN. );

A science class is studying fingerprints. The samples need to be magnified 80 times in order for students to identify key features. If an actual sample is 20 millimeters long how many CENTIMETERS is the magnified image.

Same concept different problem, but with 60 times magnification, and the sample being 16 millimeters how many cm then?

Please, step by step.
