What is the equation of the midline for the function y=3cos (x-pi)-4

3 cos((x - π ) - 4 = 3 cos(x) - 4 since cos(x-π) = cos(x)  

-1 ≤ cos(x) ≤ 1  

-3 ≤ 3cos(x) ≤ 3  

-3-4 ≤ 3 cos(x)-4 ≤ 3-4  

-7 ≤ 3 cos(x) ≤ -1  

The range is -7 to -1 so the midpoint is (-7-1)/2 = -4  

y = -4 is the equation of the midline

Step-by-step explanation:

there you go

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
