Best ResponseYou've already chosen the best response.1yes, i work this the same, however when inputing it online, coming back incorrect maybe the symbol

Best ResponseYou've already chosen the best response.1help, how to write the correct solution set (43x)^2=39?

Best ResponseYou've already chosen the best response.0If you expand it you get: (43x)*(43x)=9x^2 24x +16

Frank1991

Best ResponseYou've already chosen the best response.0and then = 9x^2 24x +16 39 =0=9x^2 24x 23

Best ResponseYou've already chosen the best response.0and use the abc formula

Best ResponseYou've already chosen the best response.0i mean the Quadratic formula

Best ResponseYou've already chosen the best response.1@ Frank 1991yes I got what you where saying

johnson32

Best ResponseYou've already chosen the best response.1i see what you have here, and i have similar, I guess I need to simplify this because it does not show in my options in labs

Best ResponseYou've already chosen the best response.1@Frank1991, i meant have to simplify all radicals. heck its multiply choice

Best ResponseYou've already chosen the best response.1use the square root property to solve for the equation. (x9)^2=64

Frank1991

Best ResponseYou've already chosen the best response.0in the last case you could say \[\sqrt{(x9)^{2}}=\sqrt{64}=8=x9\]

Best ResponseYou've already chosen the best response.1@Frank1991, my answers are as yours, but when i type them in them in the computer labs they come back wrong.

Best ResponseYou've already chosen the best response.0oh that is strange you could check what wolframalpha is saying

johnson32

Best ResponseYou've already chosen the best response.1@Frank1991 sure thing

Frank1991

Best ResponseYou've already chosen the best response.0Yes wolfram alpha is also saying something different

Best ResponseYou've already chosen the best response.0I forgot about that a sqaure could also be negative

Best ResponseYou've already chosen the best response.0so we got one answer but forgot about the second

Best ResponseYou've already chosen the best response.1The formula A=P (1+r)^2 gives the amount A in dollars that P dollars will grow to in 2 years interst rate r ( where r is given as a decimal), using compound intreset. What interest rate will cause $3000 to grow to $3370.80 in 2 years..

Best ResponseYou've already chosen the best response.1The formula S=16t^2 is used to approximate the distance S, in feet, that an object falls freely from the rest in t seconds. The height of a building is 1048 feet. How long would it take for an object to fall from the top?

Frank1991

Best ResponseYou've already chosen the best response.0To the first question:3000=3370.8(1+r)^2 => 3000=3370.8 (r^2 +2r +1) => r^2 +2r +1 = 3000/3370.8 => r^2 +2r +(13000/3370.8) = 0 and solve this for r. Probably one of the answers is negative and that makes no sense

Best ResponseYou've already chosen the best response.0second one: 1048=16 *t ^2 => t = squarroot( 1048/16) = ...

Best ResponseYou've already chosen the best response.0I hope it helped @johnson32

Best ResponseYou've already chosen the best response.1@Frank1991 , so you got 0% interest rate,

johnson32

Best ResponseYou've already chosen the best response.1@mayankdevnani , yes thank you got that one solve already

Frank1991

Best ResponseYou've already chosen the best response.0no r is the intrest rate

johnson32

Best ResponseYou've already chosen the best response.1@Frank1991 , I got 65.5 seconds for the object falling at

Frank1991

Best ResponseYou've already chosen the best response.0so use the quadratic formula for: r^2 +2r +(13000/3370.8) = 0 and r would be your answer

Frank1991
 2 years ago
Best ResponseYou've already chosen the best response.0oh the 3000 and 3370.8 should switch

Frank1991

Best ResponseYou've already chosen the best response.0You obtain r = 2.06 or r=0.06

Frank1991
 2 years ago
Best ResponseYou've already chosen the best response.0r=2.06 makes no sense because there is an increase not a decrease, so your final answer is 0.06

Best ResponseYou've already chosen the best response.1yes I got it, thank you
