Graph the cosine function on the interval [−360, 360] showing all key points of the graph (horizontal and vertical
intercepts and maximum and minimum points). then, use the graph to answer each of the following questions.
f. arrange the following values in order from smallest to largest by using their location on the graph.
cos(135°) cos(85°) cos(−15°) cos(190°)

right

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

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.
