who can help me with calculus??!!

OpenStudy (anonymous):

I can

OpenStudy (anonymous):

ok it has tpo do with integrals

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

\[\int\limits\limits_{1}^{7} 1/\sqrt[3]{t} dt\]

OpenStudy (anonymous):

if \[f(x)=1/\sqrt[3]{t}\] \[F(x)=(3/2)\sqrt[3]{t}^2\] The result is F(7) - F(1) Calculate that for yourself

OpenStudy (anonymous):

ok thank you!

OpenStudy (anonymous):

hey you still there?

OpenStudy (jit4won):

I will help you

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

\[\int\limits_{3}^{b} 3x ^{2} dx = 37 \]

OpenStudy (anonymous):

find the value of b?

OpenStudy (jit4won):

\[\int\limits_{3}^{b}\]\[\int\limits_{}^{}3x ^{2}dx = 3x^{3}/3 = x^3\]

OpenStudy (jit4won):

substituting the limits we get \[b^3 - 3 ^3 \]

OpenStudy (jit4won):

now \[b^3 - 3^3 = 37 \]

OpenStudy (jit4won):

\[b^3 =27+37\]

OpenStudy (jit4won):

\[b^3=64 \]

OpenStudy (jit4won):

\[ b^3 = 4^3 \]

OpenStudy (anonymous):

so what happen to the 37?

OpenStudy (jit4won):

b=4 is your answer

OpenStudy (jit4won):

37 got added with 27

OpenStudy (jit4won):

37+ 27 = 54

OpenStudy (jit4won):

oh* 37+ 27= 64

OpenStudy (anonymous):
