The answer is x2 + 2xy + y2.
(cos Ф -cos Ф)² + (cos Ф + cos Ф)²
Firstly: (cos Ф -cos Ф)² = 0² = 0
Secondly :(cos Ф + cos Ф)² = (2cos Ф)². = 4. (cos Ф)² = 4cos² Ф
Mind you when you raise a cosine (or sin or tan...) to the n power, the n power should affect the cosine only and NOT the angle Ф
Answer:
36.8/2.8 = 16
Expression 1 = 368/28
Expression 2 = 3.68/.28
Step-by-step explanation:
If you move the decimal the same on both numbers of a division problem the answer stays the same.
The distance formula is d=√(x2-x1)² + (y2-y1)²
So... d =8.06226
Hope this helps
Answer:
<h2>C. g(x) = x - 6</h2>
Step-by-step explanation:
For a parent function y = f(x) and n > 0:
f(x) + n : move the graph n units up
f(x) - n : move the graph n units down
f(x + n) : move the graph n units to the left
f(x - n) : move the graph n units to the right
===================================================
We have
f(x) = x
Transformation: 6 units down
f(x) - 6 = x - 6
