Find two positive numbers whose product is 25 and whose sum is a minimum. (if both values are the same number, enter it into bot

pshichka [43]

Let xy = 25, x and y > 0.

$y = \frac{25}{x}$
$\text{Denote S as: } x + y$
$S(x) = x + \frac{25}{x}$

$\text{Minimum: }S'(x) = 0, S''(x) > 0$
$S'(x) = 1 - \frac{25}{x^{2}}$
$1 - \frac{25}{x^{2}} = 0$
$x^{2} = 25$
$x = 5 (x > 0)$

$S''(x) = \frac{50}{x^{3}} > 0, (x > 0)$

Thus, at x = 5, there lies a minimum summation, and this forms a square with side length of 5.

I NEED HELP PLEASE! THANKS :)

Semmy [17]

First, add the number of total male and female students.

216 + 207 + 198 + 194 = 815 males

193 + 214 + 197 + 201 = 805 females

Second, add to find the total number of students.

815 + 805 = 1620

Third, create a ratio from females to total students

805/1620

Fourth, simplify the fraction.

805/1620 → 161/324

Therefore, the answer is A.

Best of Luck!
