Use the inverse variation equation, y=1/2x, to answer each question. Drag and drop the correct answers into the boxes.
1. What is the constant of variation, k?
2. How does the constant of variation effect the graph of the equation?
Choices:
k=1 k=2 k=-2 k=1/2
the graph shifts closer to the origin because k is between 0 and 1
the graph shift away from the origin because k is greater than 1
the graphs are in quadrants 2 and 3 instead of 1 and 4 because k is less than 0
the constant of variation does not effect the graph

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
