I would do this by first listing the multiples of 6 until I start to see a pattern with the one's digit.
6x0=0
6x1=6
6x2=12
6x3=18
6x4=24
6x5=30
6x6=36
6x7=42
6x8=48
...
The digits in bold are the one's digits so those are the only ones we really care about. If you list just them it looks like: 0,6,2,8,4,0,6,2,8
Notice how the first set of 5 numbers seems as though it repeats in the 6th, 7th, and 8th numbers. This probably means the pattern continues infinitely so the first 5 numbers are all the one's digits that can come from multiples of 6. Thus your answer is: 0,6,2,8,or 4
Answer:
c. 198π units²
Step-by-step explanation:
We have to find the surface area of a cylinder.
We know that surface area of a cylinder= 2πrh+2πr²
where r is the radius
and h is the height of the cylinder.
here h=2 units and r=9 units
Surface area= 2π×9×2+2π×9×9
= 198π units²
Hence, correct option is:
c. 198π units²
Answer:
8x+4
Step-by-step explanation:
4(2x+1)=8x+4
Answer:
Area of a circle = 3.14 X radius X radius
= 3.14 X 4.5 X 4.5 = 63.585 m2
Hope this helps....
It is easy after using formula of t<span>he complex numbers
</span>z1= 5(cos25Deg + i sin25Deg)
z2= 2(cos80Deg + isin80Deg)
so z1/z2 =5/2cis(25Deg-80Deg)=5/2cis(-55Deg)
but we know that sin(-55Deg)= - sin(55Deg), and cos(-55Deg)=cos(55Deg),
finally the answer is Z=5/2(cos55Deg-i sin55Deg) (Z=z1/z2)
