Solving for $\frac{\mathrm{d}}{\mathrm{d}x}(f(x))\\$ :

$\frac{\mathrm{d}}{\mathrm{d}x}(f(x)) = \frac{\mathrm{d}}{\mathrm{d}x}(\sqrt{5x}) \\ f'(x) = \frac{\mathrm{d}}{\mathrm{d}x}(\sqrt 5 \cdot \sqrt x) \\ f'(x) = \sqrt 5 \cdot \frac{\mathrm{d}}{\mathrm{d}x}(\sqrt x) \\ f'(x) = \sqrt 5 \cdot \frac{\mathrm{d}}{\mathrm{d}x}(x^{\frac{1}{2}}) \\ f'(x) = \sqrt 5 \cdot (\frac{1}{2}x^{\frac{1}{2} -1}) \\ f'(x) = \frac{\sqrt 5}{2}(x^{\frac{1}{2} -\frac{2}{2}}) \\ f'(x) = \frac{\sqrt 5}{2}(x^{-\frac{1}{2}}) \\ f'(x) = \frac{\sqrt 5}{2 \sqrt x}$

Hey can you please help me posted picture of question

Bingel [31]

Total number of boys = 200
Number of left handed boys = 50

If a students is known to be a boy, the probability that he is left handed will be equal to = (Number of left handed boys) / (Total Number of boys)

So, If a students is known to be a boy, the probability that he is left handed will be = $\frac{50}{200} = \frac{1}{4}$

Thus, the correct answer is option B

Multiply. Write your answer as a fraction in simplest form. 10/11×3/7×1/2 Please explain

Mashutka [201]

You can just multiply across because you dont have to worry about a common denominator since you're not adding or substracting the fractions. Then just simplify.
