numbers:
2, 4, and 5
I am so sorry if i'm wrong!!! :|
Well the way I multiply bigger numbers is like this...
43 x 42
43
42
3 times 2 equals six
then 4 times 2 is 8
then add your zero place
then 4 times 3
and then 4 times 4
Or..something like this.
I think they down graded it by 1080.Hope this helps. :)
#11
The steepest slope would be m=5
This is the same as 5/1 so you are going UP 5 units for every one unit movement right.
#12
y=mx+b
The b is where it crosses the y axis. This is -2.
The slope is negative because it FALLS from left to right.
Rise/run is 2/7 so slope is -2/7
y = -2/7x -2
Circumference = 2 x 3.14 x radius
295.16 = 6.28 x radius
295.16 / 6.28 = radius
47 = radius
