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.

Evaluate the function below for x=2. F(x)=x^4+6x^3+3

Nitella [24]

Answer:
f(2)=67
Step-by-step explanation:
In order to evaluate the function f(x)=x^4+6x^3+3 for x=2, you must replace all of the x's with the number two and then simplify:
f(2)=2^4+6(2)^3+3
f(2)=16+6(8)+3
f(2)=16+48+3
f(2)=16+51
f(2)=67
