Find the amplitude of the function.
y-=.05 cos 6x

option D

0.5

Step-by-step explanation:

Formula to find the amplitude of function graph is

here maximum = 0.5

        minimum = -.05

Plug values in the formula

amplitude = 0.5 - (-0.5) / 2

                 = 1 / 2

                 = 0.5

Secondly,

The amplitude of y=asin(x) and y=acos(x) represents half the distance between the maximum and minimum values of the function.

y = .5cos6x

here a = 0.5

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
