Best ResponseYou've already chosen the best response.0So the equation is \[\Large t = 2\pi\sqrt{\frac{1}{32}}\] ???

Best ResponseYou've already chosen the best response.0and that's a 1 (one)?

jim_thompson5910

Best ResponseYou've already chosen the best response.0so like this \[\Large t = 2\pi\sqrt{\frac{L}{32}}\]

Best ResponseYou've already chosen the best response.0oh, t is already isolated (and solved for)

Best ResponseYou've already chosen the best response.0dw:1343424734335:dw L represents feet and i have to solve for t...in other words the 3 represents feet

Best ResponseYou've already chosen the best response.0So you're plugging in arbitrary values of L to find t?

Best ResponseYou've already chosen the best response.0which values do they want you to plug in?

Best ResponseYou've already chosen the best response.0i have to plug in 4 values...3,2,1,0

Best ResponseYou've already chosen the best response.0I'll do one and hopefully it will makes sense enough for you to be able to do the others \[\Large t = 2\pi\sqrt{\frac{L}{32}}\] \[\Large t = 2\pi\sqrt{\frac{3}{32}} ... \ \text{Plug in L = 3}\] \[\Large t = 2\pi\sqrt{0.09375}\] \[\Large t \approx 2\pi(0.306186)\] \[\Large t \approx 2(3.14159)(0.306186)\] \[\Large t \approx (6.28318)(0.306186)\] \[\Large t \approx 1.92382\]  So when \[\Large L = 3\] the value of t is approximately \[\Large t \approx 1.92382\]

Best ResponseYou've already chosen the best response.0oh that makes sense...but how do u get the answer not in decimal form...like how do solve the radical

Best ResponseYou've already chosen the best response.0Well you can't simplify \[\Large \sqrt{\frac{3}{32}}\] too much. I guess you can say \[\Large \sqrt{\frac{3}{32}} = \frac{\sqrt{3}}{\sqrt{32}}\] \[\Large \sqrt{\frac{3}{32}} = \frac{\sqrt{3}}{\sqrt{16*2}}\] \[\Large \sqrt{\frac{3}{32}} = \frac{\sqrt{3}}{\sqrt{16}*\sqrt{2}}\] \[\Large \sqrt{\frac{3}{32}} = \frac{\sqrt{3}}{4\sqrt{2}}\] \[\Large \sqrt{\frac{3}{32}} = \frac{\sqrt{3}*\sqrt{2}}{4\sqrt{2}*\sqrt{2}}\] \[\Large \sqrt{\frac{3}{32}} = \frac{\sqrt{6}}{4*2}\] \[\Large \sqrt{\frac{3}{32}} = \frac{\sqrt{6}}{8}\]  So \[\Large t = 2\pi\sqrt{\frac{3}{32}}\] becomes \[\Large t = 2\pi\frac{\sqrt{6}}{8}\]

Best ResponseYou've already chosen the best response.0but in my opinion, that's not much of a simplification

Best ResponseYou've already chosen the best response.0okayy i understand now...thanks for your help

jim_thompson5910

Best ResponseYou've already chosen the best response.0oh you can go further to get \[\Large t = 2\pi\frac{\sqrt{6}}{8}\] \[\Large t = \frac{\pi\sqrt{6}}{4}\]
