Answer:
θ = πk, 1.318+2πk, 4.965+2πk
Step-by-step explanation:
4sin(2θ) − 2sin(θ) = 0
8sin(θ)cos(θ) - 2sin(θ) = 0
2sin(θ)[4cos(θ)-1] = 0
2sin(θ) = 0
sin(θ) = 0
θ = πk
4cos(θ)-1 = 0
4cos(θ) = 1
cos(θ) = 1/4
θ ≈ 1.318+2πk, 4.965+2πk
Therefore, θ = πk, 1.318+2πk, 4.965+2πk
Can you give me some hint please
Answer:
The answer is 3 units apart.
Step-by-step explanation:
The points are (1,9) and (4,9). The y-coordinates are the same. The x-coordinates are different. To find the difference between them, you must subtract them. 4-1=3, so the points are 3 units apart!
Answer:
Step-by-step explanation:
For this problem, I'm pretty sure its asking you for the lcm of 12 and 14. It asks for how many photograghs (x) will be sold on each site, when the amount of money is the same (y).
The lcm of 12 and 14 is 84, so that means that Jessa will sell 7 paintings on the first site, and 6 on the second.
Hope this helps!!
<span>let's call the width w
l= w+6 [because l is 6 meters more than width]
Perimeter = width+width+length+length
=w+w+ (w+6) + (w+6 ) [ I substituted w+6 in place of l]
so 4w+ 12=36
4w= 36-12
4w=24
w=24/4
w=6
since length = w+6, this means that length is 6+6= 12
so width= 6 m and length = 12 m</span>
