Happy Gilmore Posted October 24, 2009 Share Posted October 24, 2009 Write the equation for a sine function with amplitude 12, period 4, reflection over the vertical axis, and down 7. Also, in the equation y=1/2 cos(x/2+5pi/6)-2 what do I do with the x/2? Link to comment Share on other sites More sharing options...

danny411 Posted October 24, 2009 Share Posted October 24, 2009 don't need homework help. But i got to manage my time better. Anyone have any ideas: Im going to bcit and taking 7 courses in jan? How do i set up my time table. I went to university 10 years ago. I never had much time to do the readings so i just concentrated on the assignments and tests. Never wrote out any notes from the chapters since it would take me too much time. Link to comment Share on other sites More sharing options...

Scope1230 Posted October 27, 2009 Share Posted October 27, 2009 So this is physics: You plan a trip on which you want to average 90km/h. You cover the first half of the distance at an average of speed of only 48km/h. What must your average speed be in the second half of the trip to meet your goal? Note that the velocities are based on half the distance, not half the time. Is this reasonable? Please help... just show me your work and I can probably understand it. Someone please show me their equations and how you set up please! This is gr 11 by the way. Link to comment Share on other sites More sharing options...

Kass9 Posted November 9, 2009 Share Posted November 9, 2009 Hey CDC!!! I need some Physics help. 1) A ball is thrown up with Vi of 30 m/s on the moon where the gravity is 1/6g. a) How high does it go? How long is it in the air? c) How long until ball is 100m high? Thanks in advance. Link to comment Share on other sites More sharing options...

100%Drunk Posted November 16, 2009 Share Posted November 16, 2009 I NEED HELP FAST PLEASE!!!!! I have one hour to make a collage that I completely forgot about. In Xanadu did Kubla Khan a stately pleasure-dome decree, where Alph, the sacred river, ran through caverns measureless to man down to a sunless sea, so twice five miles of fertile ground with walls and towers were girdled round. and there were gardens bright with sinuous rills, where blossom'd many an incense-bearing tree. And here were forests as ancient as the hills, enfolding sunny spots of greenery. But O! That deep romantic chasm which slanted, down the green hill athwart a cedarn cover. A savage place! As holy and enchanted as e'er beneath a waning moon was haunted by woman wailing for her demon lover. And from this chasm, with ceaseless turmoil seething, as if this Earth in fast thick pants were breathing, a mighty fountain momently was forced, amid whose swift half-intermitted burst, huge fragments vaulted like rebounding hail, or chaffy grain beneath the thresher's flail, and 'mid these dancing rocks at once and ever, it flung up momently the sacred river. Five miles meandering with a mazy motion, through wood and dale the sacred river ran. Then reach'd the caverns measureless to man, and sank in tumult to a lifeless ocean. And 'mid this tumult Kubla heard from afar ancestral voices prophesying war! The shadow of the dome of pleasure floated midway on the waves Where was heard the mingled measure from the fountain and the caves. It was a miracle of rare device a sunny pleasure dome with caves of ice. A damsel with a dulcimer in a vision once I saw. It was an Abyssinian maid, and on her dulcimer she played, singing of mount Abora. Could I revive within me her symphony and song. To such a deep delight 'twould win me, that with music loud and long, I would build that dome in air! That sunny dome! Those caves of ice! and all who heard should see them there! and all should cry, Beware! Beware! his flashing eyes! his floating hair! Weave a circle round him thrice, and close your eyes with holy dread! for he on honey-dew hath fed, and drunk the milk of Paradise. of this poem could you name a few images I would use for my collage, I have no idea what the frack this poem is even about Link to comment Share on other sites More sharing options...

Jarvis Posted November 18, 2009 Share Posted November 18, 2009 I know the answer is 1. Can't figure out how to get there. I get stuck after taking a derivative, then the form is 0 times infinity. Link to comment Share on other sites More sharing options...

amkia Posted November 26, 2009 Share Posted November 26, 2009 You are standing at x = 8km and your assistant is standing at x = 2km. Lightning bolt 1 strikes at x = 0km and lightning bolt 2 strikes at x = 13km. You see the flash from bolt 2 at 11 nano seconds and the flash from bolt 1 at 51 nano seconds. What are the times that your assistant sees bolt 1 and bolt 2 respectavley? i need to use einsteins theory of relativity, when using gallaleon relativity, the answer is wrong because the bolts travel at c = 3.0x10^8m/s, therfore there is time dialation. i asked my prof about this question and he said he would give me one hint; both you and the assistant are in the same reference frame.
