Answer:
Step-by-step explanation:
cos x cos (3x)+sinx sin (3x)=0
cos (x-3x)=0
cos(-2x)=0
cos 2x=0=cos (2n+1)π/2
where n=0,1,2,3∞∞∞∞
2x=(2n+1)π/2
x=(2n+1)π/4
put n=0,1,2,3
x=π/4,3π/4,5π/4,7π/4
Answer:
I'm assuming p is (3, -5) since M is (-2, -5) if so, then the perimeter should be 16.
Hello :
the formula is : an = a1+(n-1)d a1 : the first term d : is the common diff
an = 1+(n-1)(4)
an =1+ 4n-4
an = 4n +<span>[ -3 ]</span>
The answer is B. I think. because they both pass the vertical line test both times so I'm assuming it is one to one but both sections are functions if that helps any it's correct
