so um, i was wondering if anyone could tell me how to find the area of a part of a parabola, preferably without using any calculus (the shaded part is the part i need to find)

i dont' need just an answer, i need how to actually do it (plus i highly doubt there's enough information on there to get an exact answer)
Is that all the info you are given?
Whats the equation of the parabola?
It can't be y=x^2 since its all the way down there.
Also what are the coordinates of the intersecting points of the line y=2|x+2| and y-60 to the parabola?
well the line is actually y=21X=21, and i'll just update the picture with everything else i know already. and the intersect of y=-60, and y=21X+21 is (-3.857 , -60)

(the two equations inside the shape are two different forms of the equation for the parabola)
god... i have to start this crap again in 2 weeks :(
I don't have to worry about this for like 2 years.
Yay being in ninth grade!
damn, i'm in 9th too, but my old school was crazy and started people in pre-algebra in 5th :(
Just ask your teacher for help xD
Yea ask the teacher. I forgot how to do area b/w curves without integration -_-
yeah i asked my teacher, but he said he didn't know any way to do it without calculus, but he doesn't actually know a whole lot about math seeing as he's suposed to be a french teacher -_-
You too man?Quote:

Im getting into "Senior" school - Year 11 Woo.
Btw Neiromaru, what is a French teacher doing teaching maths? That's a bit concerning. :o:P
On that thought - anyone noticed that Australians say "maths" but Americans say "math" and Aussies say "Sport" but americans say "sports"?
Just thought I'd say that, heard it somewhere before considering this is random musings :lol:
OMG! Except my little bro he says "math" but he's a retard.Quote:

& yes starting yr11 this year... Hopefully 2 units of the maths wont kill me... Being good at it sucks & what do you use parabola's for anyway?...
