Find the derivative of [tex]f(x)=7 \sqrt[3]{x}+8 \sin x-12[/tex]
a.) [tex]f^{\prime}(x)=\frac{7}{3 x^{\frac{2}{3}}}-8 \cos x-12[/tex]
b.) [tex]f^{\prime}(x)=\frac{7}{3 x^{\frac{2}{3}}}+8 \cos x[/tex]
c.) [tex]f^{\prime}(x)=\frac{21}{x^{\frac{2}{3}}}+8 \cos x[/tex]
d.)[tex]f^{\prime}(x)=\frac{7}{3 x^{\frac{2}{3}}}-8 \cos x[/tex]
Answer (1)
Well, the time is 120 seconds, that is 2 minutes each 60 seconds. You multiply each speed with 120 and you get the final results.
