So you just have to multiply 12 times 12 which is 144

12 ×12 =144 squares. an array is found by multiplying length units by width units. Much like finding the area

Find the standard form of the equation of the parabola with a focus at (-2, 0) and a directrix at x = 2.
krok68 [10]

Answer:

y^2=\frac{1}{8}x

Step-by-step explanation:

The focus lies on the x axis and the directrix is a vertical line through x = 2.  The parabola, by nature, wraps around the focus, or "forms" its shape about the focus.  That means that this is a "sideways" parabola, a "y^2" type instead of an "x^2" type.  The standard form for this type is

(x-h)=4p(y-k)^2

where h and k are the coordinates of the vertex and p is the distance from the vertex to either the focus or the directrix (that distance is the same; we only need to find one).  That means that the vertex has to be equidistant from the focus and the directrix.  If the focus is at x = -2 y = 0 and the directrix is at x = 2, midway between them is the origin (0, 0).  So h = 0 and k = 0.  p is the number of units from the vertex to the focus (or directrix).  That means that p=2.  We fill in our equation now with the info we have:

(x-0)=4(2)(y-0)^2

Simplify that a bit:

x=8y^2

Solving for y^2:

y^2=\frac{1}{8}x

How do you find the equation that is perpendicular to 2x-5y=20, passing through the point (7,-8)?
IrinaK [193]
To find a perpendicular line you first need to see the equation in slope intercept form. To do that you need to solve for y. 

2x - 5y = 20 ---> subtract 2x from both sides
-5y = -2x + 20 ---> divide by -5
y = 2/5x - 4

Now that you have this, note that a perpendicular line has opposite and reciprocal slope. Since the slope in our equation is 2/5, that means the new line will have -5/2 slope. So we use the point given and the slope to find the y intercept. 

y = mx + b
-8 = -5/2(7) + b ---> multiply
-8 = -35/2 + b ---> add 35/2 to both sides
19/2 = b

Now use our new slope and new y intercept to write the new equation. 

y = -5/2x + 19/2
