Question

write an article on role of a student for your annual school magazine​

Answer 1

Given :- $f(h) = \frac{5h}{4h {}^{2} + 5 }$

To Find :- The approximate amount of a drug.

Solution :-

$h = 3 \: + \frac{1}{2} = 3\: + 0.50 \: = 3.50$

$f(h) = \frac{5h}{4h {}^{2} + 5 }$

$f(3.5) = \frac{5 \: \times \: 3.5 }{4(3.5) {}^{2} + 5}$

$f(3.5) = \frac{17.5}{4(12.25) \: + \: 5}$

$f(3.5) = \frac{17.5}{49 \: + \: 5}$

$f(3.5) = \frac{17.5}{54}$

$f(3.5) = 0.3241$

In Percent, 32.41%

Hence, the approximate amount of a drug = 32.41%.

Hence, the final answer is 32.41%.
