If tana=a
then find sin4a-2sin2a/ sin4a+2sin2a

The value of the given expression is

Step by step Explanation:

Given that

To find the value of

Let us find the value of the expression :

( by using the formula here A=2A)  

(using    here A=2A)

(using here A=2A)

 ( using here A=2A )

  (since tanA=a given )

Therefore

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
