What would be the maximum value for f(x) = −5x2 + 9
Maru [420]
Well, looking at the expression, it has a -5 on the leading term, that means is not just a quadratic, but is a parabolic graph and because the coefficient of the leading term is negative, is upside-down, or opening downwards.

because it opens downwards, it looks like an arc, comes from the bottom up up up gets to a "maximum" or U-turn (vertex), then goes back down down down.  So, where's the vertex anyway?

\bf \textit{ vertex of a vertical parabola, using coefficients}\\\\
\begin{array}{lccclll}
f(x) = &{{ -5}}x^2&{{ +0}}x&{{ +9}}\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad  {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)
\\\\\\
\left( -\cfrac{0}{2(-5)}~~,~~9-\cfrac{0}{4(-5)} \right)\implies (0~~,~~9)

so, that's where the vertex is, and the maximum value for f(x), is the y-coordinate of course, or 9.

Perform the indicated operation.
Vladimir [108]

\frac{2(a-3)}{(3+a)(3-a)}

Step-by-step explanation:

This can be written as;

\frac{8}{9-a^2} *\frac{a^2-6a+9}{4a^2-4a-24}

Perform factorization

9-a²=difference of squares formula

(3+a)(3-a)

4a²-4a-24

4(a²-a-6)

4(a²-3a+2a-6)

4(a(a-3)+2(a-3))

4((a+2)(a-3))

a²-6a+9

a²-3a-3a+9

a(a-3)-3(a-3)

(a-3)(a-3)

Rewrite the operation as;

\frac{8}{(3+a)(3-a)} *\frac{(a-3)(a-3)}{4((a+2)(a-3)}

cancel common to remain with;

\frac{2(a-3)}{(3+a)(3-a)}

The volume of a shipping container is 448.656 cubic inches, and it can hold 24 smaller boxes. What's the volume of each of the s
madreJ [45]

Answer:

The volume of each of the smaller boxes = 18.694  inches³

Step-by-step explanation:

The volume of Shipping container = 448.656  inches³

The shipping container hold small boxes of numbers = 24

So, The volume of each of small boxes = \frac{448.656}{24} inches³

Or, The volume of each of small boxes = 18.694  inches³

Hence The volume of each of 24 small containers is 18.694 inches³ Answer
