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.

Round nine point four two to one decimal place

Alona [7]

Well in order to round 9.42 to the closest whole number we must know that. anything below 5 we round down and 5 and up we round up

So 9.42 becomes 9

of if your wanting to round to the nearest tenth it would be 9.4 you drop the 2 because you rounded down since it was lower than 5.

For each function, find f(-1), f(0), and f(2). f(x)=4x-3 f(x)=1/2x+2

icang [17]

f(x)=4x-3
f(-1)=4(-1)-3=-4-3= -7
f(0)=4(0)-3= -3
f(2)=4(2)-3=8-3= 5

f(x)=1/2x+2 
f(-1)=1/2(-1)+2=1/(0)= unknown
f(0)=1/2x+2=1/2(0)+2=1/2
f(2)=1/2x+2=1/2(2)+2=1/6
