Suppose you have 48 feet of fencing to enclose a rectangular dog pen. The function : A = 24x-x^2 , where x = width , gives you t
Viktor [21]
Check the picture below, that's a parabolic graph of a quadratic equation with a negative leading coeffficient, like this one, the one in the graph is just for initial velocity, but, the highest point is at the vertex for any of these parabolas.

and this one is not exception, so where's the vertex?  what's A or the y-coordinate when the vertex is reached?, well, let's check.

\bf A=24x-x^2\implies A=-1x^2+24x+0\\\\
\textit{ vertex of a vertical parabola, using coefficients}\\\\
\begin{array}{lccclll}
A = &{{ -1}}x^2&{{ +24}}x&{{ +0}}\\
&\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{24}{2(-1)}~~,~~0-\cfrac{24^2}{4(-1)} \right)\implies \left(12~~,~~ 0+\cfrac{576}{4} \right)
\\\\\\
\left(\stackrel{width}{12}~~,~~\stackrel{Area}{144}  \right)

so, that's the vertex, and when the width is that much, the Area reaches a maximum of that much.

1) Solve the following System of Equations by Graphing. Label the solution and all intercepts. (5 points)
Iteru [2.4K]

Answer:

(-0.6 , -5.2)

Step-by-step explanation:

4x-2y=8

y=12x+2

just graph the line of each equation of the system and then locate the

intersection point

the coordonates of that point are pair solutio to the system

check the picture below for the graph.

Express your answer in the form (a + bi) <br><br>(21 + 2i) + (13 + 8i) =
pantera1 [17]

Answer:

The answer to your question is   (34 + 10i)

Step-by-step explanation:

Data

            (21 + 2i) + (13 + 8i) =

To solve this operation, just sum up the whole numbers and get a result then, sum up the imaginary numbers and get another result. Finally, write the result.

           

-Whole numbers            21 + 13 = 34

-Imaginary numbers       2i + 8i = 10i

Result                               (34 + 10i)
