Perpendicular means the slope is the opposite inverse
Lets re-organize the equation so its more friendly
4x-2y=9
-2y=-4x-9
y=2x+9/2
The slope of this is 2, so the opposite inverse would be -1/2
So far our new equation looks like y=-1/2x+b
To find B we will input the coordinates (4,6) for their respective x,y values
6=-1/2(4)+b
6=-2+b
b=8
y=-1/2x+8
The answer is B

The spray from a lawn sprinkler makes a circle 40 feel in radius. What are the approximate diameter, circumference, and area of
Fittoniya [83]
Our first step is to figure out what formulas are needed for diameter, circumference, and area of a circle.

Diameter is simply twice the size of the radius so:
2 * radius = 2 * 40 feet = 80 ft.

Circumference = 2 * pi * radius = 80 ft * pi 
If we say that pi = 3.14, then:
circumference = 251.2 ft.

Area = pi * radius^2 = pi * 1600 ft^2
Once again, if we assert pi = 3.14, then:
area = 3.14 * 1600 ft^2 = 5024 ft^2.

Find the asymptotes of the function. Select all that apply.
devlian [24]

An asymptote is a vertical horizontal or oblique line to which the graph of a function progressively approaches without ever touching it.

To answer this question we observe the graph. All the values of x and y must be identified for which the graph of the function tends to infinity.

It is observed that these values are:

x = -1

x = 3

y = 0

The first two corresponds to the equations of a vertical line. The third corresponds to horizontal line, the axis of x. It can be seen that although the graph of the function is very close to these values, it never "touches" them
