I believe the answer is 1848.
= 3 - 3cos x - 2(1- cos^2 x)
= 2cos^2 x - 3cos x + 1
=(cos x -1)(cosx - 1/2)
now cos x = 1 or cos x= 1/2
draw a graph we get = + ve values
hence .. 0 ,180,360 and 60,240, degrees in range x<2pi
If you would like to find the average of 766 and 878, you can calculate this using the following steps:
766 + 878 = 1644
1644 / 2 = 822
The correct result would be 822.
Answer:
3y+4
Step-by-step explanation:
this is combining like terms meaning the two "y" numbers combine together
9y-6y
then you just keep the 4 since it cannot be combined with anything else here since it has no variable
232
A=2(WL+HL+HW)
so 2(8*10+2*10+2*8)
