Hii if he answered 122 questions correct, or 60%, then there were a total of 200 questions on the exam
Step-by-step explanation:
the first derivative by using
f’(x)=xn = nx^(n−1)
f(g(x)) = f’(g(x))g’(x)
So f’(x)=2(x⅔ -1)*(2/3 x^(-1/3))=![\frac{4*(x^{\frac{2}{3} }-1) }{3*\sqrt[3]{x} }](https://tex.z-dn.net/?f=%5Cfrac%7B4%2A%28x%5E%7B%5Cfrac%7B2%7D%7B3%7D%20%7D-1%29%20%7D%7B3%2A%5Csqrt%5B3%5D%7Bx%7D%20%7D)
Second derivative by using:
h’(x)=f(x)*g(x)=f(x) g’(x) + f’(x) g(x)
f’’(x)=
The answer is D (the fourth option), during EVAPORATION
5*5 is not 2510.
* Means multiplication. 5*5=25
