The following table gives the height h of a rocket in kilometers at a given time t in seconds. (24,12) (27,17) (30,23) (33,31) (36,40) (39,51) With the coordinates being in the form (t,h). Estimate the velocity of the rocket at time = 39 seconds as best you can. Give your answer in km/sec


And Part B for full points of best answer: Using your answer in part a estimate the position of the rocket at time = 40 seconds.

Alright, I'm studying for a test I have tomorrow and had a little question about the half angle formula.

In my textbook there is a section of questions with the directions: "Use the half-angle identities to find the exact values in problems 25-29"

the problems are as listed
25. cos^2(pi/3)
26. sin^2(pi/6)
27. sin^3(pi/6)
28. cos^2(pi/12)
29. sin^2(pi/8)

I know what the half angle formulas are (sin(x/2) = +/- sqrt((1-cosx)/2), etc. But I have trouble applying it. I don't know how to apply it regularly especially to numbers like pi/12 that don't have answers derived from the unit circle. I'm especially lost on what to do w/ the whole exponent in this set of questions. If someone can help me out, then I owe them. Thanks

I just started taking calculus and the other day my teacher drew a graph of a curve on the board that intersected the x axis. He asked the class what the limit would be as x approaches 0. I was alittle confused by this because I don't understand how there can be a limit as x approaches 0 when the line itself actually goes through 0 and is therefore not approaching 0. Can someone please explain? Thanks.

Three men went to motel. Clerk charged $10 each. Men went to their rooms. Clerk discovered he had charged too much. Gave 5$ to bell hop to return to the men. Bell hop could not split $5 evenly. He kept $2 and gave the men $1 each. Each man now has paid $9 each. That comes to $27. The bell hop got $2. That total $29. Where did the other $1 go?

Make a conjecture about the relationship between
three consecutive whole numbers based on this relationship illustrated by the numbers 3, 4, and 5: (3 x 5) = 4 to the 2 power - Can you find acounterexample?

1. The demand for chocolate chip cookies is given by equation 1, where Qd is the quantity of cookies demanded in a year (in millions), and P is the price per cookie (in dollars).



Qd = 8 - 30*P (1)





The supply of chocolate chip cookies is given by equation 2, where Qs is the quantity of cookies supplied (in millions):



Qs = -2 + 20*P (2)









a. Draw the demand curve and the supply curve for chocolate chip cookies, labeling your axes and the curves. (Put P on the vertical axis, Q on the horizontal axis. Substitute values for P (start with $.10 and use increments of $.10) and solve for Qd and Qs.)



b. Show the equilibrium price and quantity by drawing dashed lines from the equilibrium to each axis.

Looking to find the conversion formula or "tool" to figure the difference between:

1st conversion request: $ 82 million in 1981 vs. 2006

Couple of factors: public bonds sold to finance project, rural mountains of Colorado, water works project - flood control & water storage, owner/operator - municipality, Army Corp of Engineers oversight.

2nd conversion request: $ 101 million in 1985 vs. 2006.

Couple of other factors: public bonds sold to finance project; locale - Boise, ID; hydro-electric power plant(revenue generator); secondary function to water works project - flood control & water storage, owner/operator - municipality, Army Corp of Engineers oversight, etc.

I'm currently working on $ 333M const. project; city of San Francisco is client/owner once complete.

It would be great if any of you could help figure out the difference in value to the different projects here. Very curious.

Thank you for your help.
