Answer:
x = pi / 2 or pi / 6 or 5 pi / 6
Step-by-step explanation:
2 cos x sin x –cos x = 0
cos x ( 2 sin x – 1) = 0
cos x = 0 or 2 sin x – 1 = 0
x = pi/2 or sinx = 1/2
x= pi /2 or x = pi/6 or pi-pi/6
x = pi / 2 or pi / 6 or 5 pi / 6
as for sinx = k
if x is a solution, pi-x is also a solution
Answer:
y = -5x + 2

Hi there!
The correct answer for you is 270.88.
To round to the hundreth's place (.0<u>1</u><u />), you need to take the number in the thousand's place (.00<u>1</u>), and determine if the number needs to go up or down.
If the number in the thousand's place is <u>greater</u> than 4, then the number goes up.
360.72<u>7</u> --> This means that the hundreth's number goes up to 3.
If the number in the thousand's place is <u>lesser</u> than 5, then that number stays the same.
89.85<u>2</u> --> This means that the hundreth's number stays the same.
After you round, then just subtract:
360.73 - 89.85 = 270.88.
I hope this helps!

Answer:
81.6814
Step-by-step explanation:
there are 10 numbers you want either a 4 or 7 ( 2 numbers)
so probability is 2/10 which reduces to 1/5
