Answer:

neither

Step-by-step explanation:

Slope of the first line: (y2 -y1)/(x2-x1) = (3-(-5)/-1 = 8/-1 = -8

Slope of the second line: (2-3)/4-(-4) = -1/8

They are neither parallel nor perpendicular. In fact the two lines have different slope so they can’t be parallel. In addition the product of their slope is not -1, so they can’t be perpendicular,

The vertex of this parabola is at (2, -4). When the y-value is -1, the x-value is 3. What is the coefficient of the squared term

Blizzard [7]

$\bf ~~~~~~\textit{parabola vertex form}
\\\\
\begin{array}{llll}
\boxed{y=a(x- h)^2+ k}\\\\
x=a(y- k)^2+ h
\end{array}
\qquad\qquad
vertex~~(\stackrel{2}{ h},\stackrel{-4}{ k})\\\\
-------------------------------\\\\
\underline{y}=a(\underline{x}-2)^2-4
\\\\\\
\textit{we also know that }
\begin{cases}
y=-1\\
x=3
\end{cases}\implies \underline{-1}=a(\underline{3}-2)^2-4
\\\\\\
3=a(1)^2\implies 3=a$

"the fromula for the perminter of a rectangle is given by P= 2L +2W where l is the length and w is the width. Assume the ermiter

Juli2301 [7.4K]

Answer:

The length of rectangular plot of land is 160 ft.

Step-by-step explanation:

L = 2 W (the length is twice the width)

P = 480 ft. (perimeter of rectangular plot of land)

L = ?

2. 2W + 2W= 480 ft >>> (2 times twice width=L) + 2W=480 ft.

4W + 2W= 480 ft >>>> 6W= 480 ft.

W= 80 ft.

L = 2. 80 = 160 ft. (Length is twice the width)

P= 2L + 2W (formula for the perimeter)

2. 160 + 2. 80 = 480 ft.
