Best ResponseYou've already chosen the best response.0in other words, the height of each partition is simply the distance from f(x) to g(x)

Best ResponseYou've already chosen the best response.0\[\int f(x)g(x)dx\] no you wont, all that changes is a sign and area is always positive for drop a sign

Best ResponseYou've already chosen the best response.0\[\int_{3}^{2} e^{0.8x}(2^{0.5x} +1)dx\] hmm, might need to write that out better

Best ResponseYou've already chosen the best response.0you might wanna check to see that nothing cross tho

Best ResponseYou've already chosen the best response.0if it does then you gotta split it up at the intersection

Best ResponseYou've already chosen the best response.0does f(x)=g(x) at any point in the interval?

Best ResponseYou've already chosen the best response.0Let me say again that the graph is important. On this interval the graphs intersect and therefore the integral must be seperated.

Best ResponseYou've already chosen the best response.0yes, intersections are important; height? not so much :)

Best ResponseYou've already chosen the best response.0(1.282, 0.359) is the intersection right?

Best ResponseYou've already chosen the best response.0You will integrate from 3 to the point of intersection with g(x)  f(x) and then from the point of intersection to 2 with f(x)g(x)....

Best ResponseYou've already chosen the best response.0\[\int_{3}^{i} e^{0.8x}+2^{0.5x} 1\ dx+\int_{i}^{2} e^{0.8x}+2^{0.5x} 1\ dx\] where i is the intersection of f and g

Best ResponseYou've already chosen the best response.0and if one of those is negative, then toss out the "" sign :)

Best ResponseYou've already chosen the best response.0yes I need to solve it by hand, and I did what you just said but i got the wrong answer

Best ResponseYou've already chosen the best response.0the wolf agrees that 1.282 is the intersect

anonymous

Best ResponseYou've already chosen the best response.0That is correct....but that is not solving by hand as I stated earlier.

Best ResponseYou've already chosen the best response.0\[\int\limits_{3}^{1.282} 2^{0.5x}e ^{0.8x} dx + \int\limits_{1.282}^{2} e ^{0.8x}(2^{0.5x}) dx\]

Best ResponseYou've already chosen the best response.0its checking if her results are accurate tho.

amistre64

Best ResponseYou've already chosen the best response.0you might be better of with an exact intersect ....

Best ResponseYou've already chosen the best response.0and who is making you do this by hand?

Best ResponseYou've already chosen the best response.0its one thing to understand a concept; its another to torture ....

anonymous

Best ResponseYou've already chosen the best response.0No...It is important to understand the concept and to use technology that is required in the classroom and on ap exams... I can help her learn to enter the information into the calculator and how she must set it up by hand to write the integral that represents the area. Dropping a sign because area is not negative is not good enough reasoning for a solution.

Best ResponseYou've already chosen the best response.0\[[2*2^{0.5x} 5/4e ^{0.8x}] + [5/4 e ^{0.8x}+2*2^{0.5x}]\]

Best ResponseYou've already chosen the best response.0oh but it is; since 53 = 2, and 35 = 2 all that changes is sign, not abs value
