Answer:
Step-by-step explanation:
equation of a circle:
where (h, k) = center and r = radius
From inspection, we can see that the center of the circle = (0, 0)
and the radius = 1
Substitute into
and solve for
:
As point P is in quadrant 1, is positive, so
In 1 meter there are 1,000 millimeter.
When you go from small (mm) to big (m) you always divide the small (mm) by what the equivalent of 1 big (m) but in terms of the small (mm)
^^^That's a bit confusing so I will work it out so it makes more sense...
^ this is the equivalent to 1 meter (the big in this case)
3 m = 3,000 mm
Hope this helped! Let me know if there is anything else that I can do!
Answer:
i
Step-by-step explanation:
Multiplying by i repeats the pattern .
Thus, any i⁴ⁿ = 1
If n = 3, 4n = 12, so
i¹² = 1 and
i¹³ = i¹ = i
