Plz help me thanks soo much and explain too :)

Answer:

$f(0) = 14$

Step-by-step explanation:

Given

$f(x) = \left \{ {{|x - 8| + 6 \ x$

Required

Find f(0)

From the piecewise function, we have the following as values of f(x):

$f(x) = |x - 8| + 6$

If $x < 4$

$f(x) = 15$

If $x \ge 4\\$

f(0) implies that $x =0$ and $0$

So, we make use of the first function, which is:

$f(x) = |x - 8| + 6$

Substitute 0 for x in $f(x) = |x - 8| + 6$

$f(0) = |0 - 8| + 6$

$f(0) = |- 8| + 6$

$|-8| = 8$

So, the expression becomes

$f(0) = 8 + 6$

$f(0) = 14$

Hence, the value of f(0) is 14

If (x - 3) represents the side of a cube, what is the polynomial that represents its volume?

hichkok12 [17]

Answer:

x³ - 9x² + 27x - 27

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ( s is the measure of the side ) , thus

V = (x - 3)³

= (x - 3)(x - 3)(x - 3) ← expand the second/ third factors using FOIL

= (x - 3)(x² - 6x + 9) ← distribute

= x³ - 6x² + 9x - 3x² + 18x - 27 ← collect like terms

= x³ - 9x² + 27x - 27

The back of jake's property is a creek. Jake would like to enclose a rectangular area, using the creek as one side and fencing f

kow [346]

Answer:

The maximum possible area of the pasture is 26,450 feet square.

Step-by-step explanation:

Let us assume the width of the rectangular area = m ft

and the length of the area = k ft

Also assume: ( one side with k units IS NOT FENCED)

So, the total perimeter of the fencing is:

2 m + k = 460

or, k = 460 - 2m ........ (1)

Now, AREA OF THE RECTANGULAR PORTION = Length x Width = k x m

Put k = 460 - 2m

We get: A = m (460 - 2m)

or, A = 460 m - 2m²

We need to find the maximum for the parabolic function A = 460 m - 2m²

The function has a maximum value as the quotient in front of x^2 is negative: -2 < 0

A (max) = $c-\frac{b^2}{4a}$ where a = -2, b = 460, c = 0

= $-\frac{(460)^2}{4(-2)} = 26,450$

A max = 26,450 sq ft.

The maximum possible area of the pasture is 26,450 feet square.
