Answer:

6, - 36 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - \frac{b}{2a}

f(x) = x² + 12x ← is in standard form

with a = 1, b = 12, c = 0 , then

x = - \frac{12}{2} = - 6

Substitute x = 6 into f(x) for corresponding value of y

f(6) = 6² + 12(- 6) = 36 - 72 = - 36

vertex = (6, - 36 )

Find the slope of the line that contains (6,-4) and (-4,-4)
frez [133]

Answer:y = -4

Step-by-step explanation: In order to find the slope by these two points, (6,-4), and (-4,-4), you must use the slope formula:

rise/run, which is this case, is y2-y1 / x2 - x1 <--- this is the slope formula

Let 6 be x2, -4 be x1, y2 be -4, and y1 being -4, plug these numbers in.

-4-(-4) / 6- (-4)

-4 + 4/ 6 +4

0/10 The slope of the line is zero, with a y-axis at -4. We know this because there is a zero in the final result and the y- coordinate between (6,-4) and (-4,-4) do not change in the slightest.

The final answer is then y = -4

A cube has a surface area of 486 cm2. What is the side length ?
astraxan [27]
A Cube, has all equal sides, namely, the length, width and height
are all equal to each other

so..  notice the picture added here
you have really, 6 squares, stacked up to each other at the edges

so...what is the Area of one of those squares?
well, if the sides are equal, let's say the side is "x" long, then
the Area is x\cdot x \implies x^2

well, you have 6 of those squares, thus \bf \textit{surface area of a cube}=&#10;\begin{cases}&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)+\\&#10;(x\cdot x)\\&#10; --------------\\&#10; x^2+x^2+x^2+x^2+x^2\\&#10;6x^2&#10;\end{cases}&#10;\\\\&#10;\textit{we know the Area is }486\ cm^2\qquad thus&#10;\\\\&#10;\textit{surface area}=6x^2\implies 486=6x^2

solve for "x", to get one side's length
