I think your equation should say “h = -16t^2 + 32t” - the “-162^2” part doesn’t make sense.  He goes up and down following a parabola, so there has to be a t^2 term somewhere for this equation to work.\n\nI’m going to assume that it should be -16t^2 and go from there.  To find the point where he gets to 14 feet, simply set the equation to 14:\n\nh = -16t^2 + 32t\n14 = -16t^2 + 32t\n0 = -16t^2 + 32t – 14\n0 = 8t^2 - 16t + 7\nt = [16 +/- sqrt((-16)^2 - 4(8)(7))] / 2(8)\nt = [16 +/- sqrt(256 - 224)] / 16\nt = [16 +/- sqrt(32)] / 16\nt = 1 +/- sqrt(2)/4\nt = 0.65s, 1.35s\n\nSo at 0.65s and 1.35s, he was at 14 feet.  Subtract the two and you find that he was at or above 14 feet for 0.7s.  (For a precise time, you can subtract [1 + sqrt(2)/4] - [1 - sqrt(2)/4] and get sqrt(2)/2.)

Take it to someone who knows what they are doing. \n\nWe've answered this question about 8 times for you. \n\nBring it to me, and I'll fix it for you - only if you quit posting the same question.

I'd suggest searching for such problems here on yahoo answers.  You can find out how to do it.

Output work 3.2J\nInput work 12 x 0.3 Nm = 3.6 J \nEfficiency = output work / input work = 3.2/3.6=0.88=88%

I don't understand.  Can you explain the problem a little better?

use synthetic  divsion method \ni think this link would help\nhttp://www.purplemath.com/modules/synthdiv.htm

Looks as though this is some kind of assignment. No? Maybe you ought to think it all through and provide your own answers. You can do it!!\n\nChow!!

I do not understand how the "problem" has to do with the question. But to answer the first part...\n\nThe cell should contain \n=POWER(number, power)\n\neg. =POWER(5, 2) would display 25\n\nA cubic root would look like this...\n=POWER(number, 1/3)

H*W= area\nheight times width\n\none side has a height of 8 and its width is 9 thus the area would be 72

check brilliant tutorials homepage...they have posted the solutions...by the way was there a set A  as well?? anyways good luck!

With this given data, it is not possible\n\nalthough the area is totalling to be 70 for both cases (7*10 and two pieces of 8*8 + 1*6) but with one division only, this is not possible\n\nPLEASE DO LET ME KNOW IF THERE IS SOME SOLUTION (i found it very interesting)

Yuo can't solve this.Because it is a formula and not an equation..If u assign some value equal to this formula such as 0 u have the solution.
