than distributed and made it standard form and got y^2 +3y -99
Oh I had a feeling it was (x+3) but didn’t go with it
oh I don't even know what you did
idk if in this context is if this is where the parabolas collide with each other or not
do I factor out a t to make a linear equation?
the teacher knows that I didn't do it because idk the steps and likely she never taught me
no. you equate the two equations together (at least from my initial read through/thought process), and solve for time. the purpose is to find a time where both cultures have the same amount of cells/unit area
So put equation a at left side and equation b at the right side?
yes. just make them equal to each other (ie. both equations have the same end result)
Wow I still don’t understand
But why 2 specifically?
yea it is
Sorry, missed that message before😅
Dw don’t know to solve the final one other than perhaps graphing
because I know s(t) is basically y
Or use elimination idk
What i think you'd do from here is add .01 t to the other side (canceling it out on the left). Then I'd divide by t so that we have .0015t on the left and .01 on the right. Then if you divide by .0015 on either side you should get t=.01/.0015 and whatever that ends up being is an answer.
I still don't get it, maybe I should see if I can use the quadratic equation and remove the S(t)
I just did elimination and got to 0.0015 t^2 - 0.01t = 0
Which is where I got
ok I could factor a t and solve to t
Then you have (t)(.0015t+.01)=0
it's just simple algebra. moving equations on the right side all over to the left (switch the sign) so the right is now zero
I would imagine there would only be 1 solution then since it's quadratic
sorry if my shortcut is confusing 😓
Yeah, that much i get
it's also 0,0 since they have the same vertex location
okay, good. i often made tiny mistakes so it's good that you double-checked me on that
yes, kinda. that's after you set the equation to 0
ok I just factored, solved for t and got 6.66
I"m on the right track, I think I can solve this right now
ok so my final answer is 0.287, idk how f(x) even works
oh wait I forgot the square
nvm
can someone check if this is right btw
Ngl, once I got out of my algebra class I kinda forgot everything cause I need to memorize all my trig stuff.
So I can barely tell what is right and wrong here
