integral question?!?!?hellpp

OpenStudy (anonymous):

if it is given that $\int\limits_{2}^{4} x ^{3}dx=60 and \int\limits_{2}^{4}xdx=6 and \int\limits_{2}^{4}dx=2$

OpenStudy (anonymous):

if u had 2 find....a.$\int\limits_{2}^{2}x ^{3}dx? and \int\limits_{2}^{4}15dx? and \int\limits_{2}^{4}(x ^{4}+4)?$

OpenStudy (anonymous):

the second one is 15*2=30

OpenStudy (anonymous):

I'm not sure I understand the question.

OpenStudy (anonymous):

i think u got the 2nd one right...its jus the top n bottom parts tht change tht confuse me..

OpenStudy (anonymous):

basically..use only the given info,,n sum rules to find it

OpenStudy (anonymous):

the third one you have to separate the integrals into x^4 and 4.... then you do 60*6 + 2*4 = 368

OpenStudy (anonymous):

how do u put numbers on brackets after u integrate?

OpenStudy (anonymous):

oh! first one equals 0 because there's a rule that says if the upper and lower bounds are the negative opposites of each other, the integral equals 0.

OpenStudy (anonymous):

ohhok..i think u got all of them..thank u soo much!!

OpenStudy (anonymous):

:)

OpenStudy (anonymous):

first one is a zero, next one is 30

OpenStudy (anonymous):

last one: 1032/5
