Best ResponseYou've already chosen the best response.0Show that the value of ∫ (from 0 to 1) \[\sqrt{x+8}dx\] lies between 2\[\sqrt{2}\] amd 3.

Best ResponseYou've already chosen the best response.0so i take it instead of doing the integral.. they want the proof method.... i can try and sum it up

Best ResponseYou've already chosen the best response.0the theorems? like if it's even or odd?

Best ResponseYou've already chosen the best response.0so we know that this shaded area is almost a rectangle... and that area is BH but the B=1 so its just the H that matters.... which is between sqrt of 8 and 3......

Best ResponseYou've already chosen the best response.0that last part i meant sqrt(8) and 3 the area is between one of those 2 because this shape has a little slop on the top so it is just a little bigger then the sqrt(8) but also less then 3.... does this make sense? dw:1359001866185:dw

Best ResponseYou've already chosen the best response.0yea i see that from f(0) and f(1), the values are between 2.8 and 3, but i have trouble putting it into integral form? :(

Best ResponseYou've already chosen the best response.0putting it in integral form? you mean like actually solving it? i can show you how

Best ResponseYou've already chosen the best response.0well i think that it's asking me to write a proof or to explain it in calculus... i kinda forgot the word for it lol

Best ResponseYou've already chosen the best response.0i think it's like boundaries?

Best ResponseYou've already chosen the best response.0yes it has boundaries and limits to what its area is restricted to

Best ResponseYou've already chosen the best response.0i think it's asking me to write the boundaries in integral form.. like 2.8 < integral from 0, 1... < 3. i don't know where to start lol!

Best ResponseYou've already chosen the best response.0aah... proofs are annoying... but as long as it makes sense its ok... if u have other "real" problems ied do those 1st... generally proofs are just long explanations .... and by real problems i mean were you can do work and get a answer.. proofs are just explaining calculus to some1 who hasnt taken it... and thats really hard... but eh i think u get it and thats all that matters

Best ResponseYou've already chosen the best response.0yea lol! i understand it, but i have trouble putting it into a "calculus sentence" or whatever they call it lol. i understand the area is between the 2.8 and 3 but i'm not sure how to translate it lol
