Find the remainder when f(x) is divided by (x - k).<br><br> f(x) = 4x3 - 6x2 + 3x + 1; k= -2

laila [671]

$\frac{f(x)}{(x-k)}$
$\frac{4x^3-6x^2+3x+1}{(x+2)}$
Using Long Division, pic below
Your remainder is -61

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.

Angela bought gifts for her friends, and each gift cost $10. Let y represent the total cost and x represent the number of gifts.

Otrada [13]

each gift =$10

total=y

number of gifts =x

therefore,total= each gift * number of gifts

=$10* x
