A Ferris wheel that has a diameter of 40 feet makes one revolution every two minutes. What is the speed of the seat on the rim of the wheel (miles per hour)? If you are the last person to get on the Ferris wheel, what will the coordinated of you location be after 3 minutes? (Assume that t=0 you are at the lowest point on the rise.)

This question is for all math whizes

ok, in my algebra II book it says that y doesnt vary directly with x for the equation y=4/3x, but it does for y=4x/3

why?? i checked and they both travel throught the origin-- please explain your answers



alrite, the next question is this: how do you graph a function? ive found that x is less than or equal to three (this is domain). and that f(x) is less than or equal to -11 (this is range)-- so does this mean that i go to (-3,-11) and graph (with an open circle on the end of a line segment, instead of a line?)

what do open and closed circles indicate for a point on a graph? when do you use them?

A study done for management shows that the revenue, R, in dollars, as a function of number, x, of units produced can be modeled by R(x) = 10x - 0.0005x^2 while the cost, C, in dollars, can be modeled by C(x) = 5000 + 2x. What will the maximum profit be, in dollars?

RJ, weighing 160 lbs. sits on a teeter board 10 feet from the fulcrum. The board is kept balanced by two boys who sit on the other end at distances 8 and 10 ft from the fulcrum. When the boys exchange places the balance is preserved if RJ takes a 4-lb weight. Find the weight of each boy

How fast can you set the Earth moving? In particular, when you jump straight up as high as you can, what is the order of magnitude of the maximum recoil speed that you give to the Earth? Model the Earth as a perfectly solid object. In your solution, state the physical quantities you take as data, and the values you measure or estimate for them.

or other words, where did space itself come from?
i mean if you want to talk about the origin of the species?
how about the destiny of space itself? was there total
mass at one time, and it dissipated? or did some entity
get drunk and cause 'being' and 'non-being'? is 'god' himself
sober? or are we a result of his 'hangover'?

I am the atom great “Universe”, I divide myself in three forces: Prótons, Elétrons and Nêutrons. To the Prótons it is the positive power, but with the negative return, and to electrons it is the negative power, but with the positive return. In what it says respect to the Nêutrons is the responsibility to act the end to unbalance the positive forces or the negative in its related limits. Thus it neutralizes the start and the extremity of all the sources of being able of the universe (mainly the sun, the planets and the Interstellar system). The energies that come of the place for where to go, and go for the place of where they come.

I have to list the following in terms of size with the largest first: endoplasmic reticulum, nucleus, ribosomal sub unit, mitochondrion, nuclear pore.

I am unsure as to where the endoplasmic reticulum falls in the list as this structure appears to take up a large proportion of the cell but I have read that differential centrifugation isolates nuclei first, followed by mitochondrion and then pieces of internal membranes.

Would the following order be correct?

Nucleus, mitochondrion, endoplasmic reticulum, ribosomal sub unit, nuclear pore.

Any help woulld be appreciated - thanks!
