Hi, So i don't need help on any specific problem, I was just wondering if there was an easy way to solve optimization problems in calc. I have no problem doing most of it, its just that coming up with the functions is my biggest problem. Can anyone give me advice on coming up with the problems.

Homework Statement u of o girls club soccer team is raffling off a cicycle to raise money for new equipment. IF they charge 4 dollars per ticket they will sell 360 tickets for each 50 cent increase ticket price, they will sell 20 fewer tickets. what ticket price should they charge to maximize...

Thanks a lot for the help. the answer was 2^x-1/x.

doesn't the secant line connect those 2 points, so can't i figure out the slope using limits

the slope of the secant line

couldn't i just use the limit of 2^x+1 as x approaches 0 to find the slope?

So for when x=-1 the rise/run is .5/1 x=-2 rise over run is .75/2 and when x=-3 rise over run is .875/3 but now how would i do the expression part?

Homework Statement Find the slope of the line that joins P (0,2) and Q (x, 2^x+1) for x ≠0. type the expression using x as a variable. Homework Equations Rise over Run? The Attempt at a Solution I have a picture of the graph but i don't really know what to do, Please help. I graphed it at x=...

Homework Statement I don't know if this is a physics problem per se but its from physics class. So we were supposed to pick out a solar panel and figure out what is the cost per unit of energy for this form of solar energy? I know where supposed to use the data sheet for the panel that we...

SO could you say that for problem one would have to be B, and for problem 2 the answer would have to be A?

Homework Statement So there are 2 questions i need help with. 1. Divide the room (for the rest of this valdation) into four (4) quadrants labeled Top Left (TL), Top Right (TR), Bottom Left (BL), and Bottom Right (BR). Which of the four particle tracks indicates that the B field in the TL and...

i think its 5cm because the length of the x and y components is 5cm.

i got 7.6X10^4 by doing KQ/r^2sin45 and the answer is the same for cos45. BUt i checked the answer and its supposed to be 7.1X10^4. Any suggestions

So were the equations correct though?

awesome so 45 degrees.
