Answer:
x=22.5°
Step-by-step explanation:
(cos²x-sin²x)-sin4x+sin²2x=0
or, (cos2x)²-sin4x+sin²2x=0
or, cos²2x+sin²2x-sin4x=0
or, 1-sin4x=0
or, sin4x=1
or, 4x=90°
or, x=90°/4
or, x=22.5°
Answer:
Find the slope of the line that passes through the pair of points. (–5.5, 6.1), (–2.5, 3.1)
Use the slope formula to find the slope m
.
m
= −

ANSWER
The slope is
EXPLANATION
The slope of the line that passes through,
can be found using the formula,
So we let,
and
We substitute them into the formula to get,
This gives us,
We simplify to get,
slope = -1
