3x=sqrt(7) x=sqrt(7)/3
hi, i got the answer. not sure if anyone done math labs online, how do you input this

034 what in the world is wrong with your x's lol
yes, i work this the same, however when inputing it online, coming back incorrect maybe the symbol
@Lukecrayonz hahaha why???
Looks like a 2pi or 2r or something :P
what ever it looks like but its my habit
help, how to write the correct solution set (4-3x)^2=39?
Expand (4-3x)^2
expand?
If you expand it you get: (4-3x)*(4-3x)=9x^2 -24x +16
and then = 9x^2 -24x +16 -39 =0=9x^2 -24x -23
and use the abc formula
i mean the Quadratic formula
I'm dutch, sorry
@ Frank 1991yes I got what you where saying
i 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
@Frank1991, i meant have to simplify all radicals. heck its multiply choice
use the square root property to solve for the equation. (x-9)^2=64
in the last case you could say \[\sqrt{(x-9)^{2}}=\sqrt{64}=8=x-9\]
so x = 8+9
@Frank1991, my answers are as yours, but when i type them in them in the computer labs they come back wrong.
oh that is strange you could check what wolframalpha is saying
@Frank1991 sure thing
Yes wolfram alpha is also saying something different
I forgot about that a sqaure could also be negative
so we got one answer but forgot about the second
yes
@Frank1991 .. thanks
The 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..
The 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?
To 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 +(1-3000/3370.8) = 0 and solve this for r. Probably one of the answers is negative and that makes no sense

@johnson32 got it
second one: 1048=16 *t ^2 => t = squarroot( 1048/16) = ...
I hope it helped @johnson32
@Frank1991 , so you got 0% interest rate,
@mayankdevnani , yes thank you got that one solve already
ok
no r is the intrest rate
@Frank1991 , I got 65.5 seconds for the object falling at
so use the quadratic formula for: r^2 +2r +(1-3000/3370.8) = 0 and r would be your answer
got it
oh the 3000 and 3370.8 should switch
You obtain r = -2.06 or r=0.06
r=-2.06 makes no sense because there is an increase not a decrease, so your final answer is 0.06
got it? @johnson32
yes I got it, thank you
