Answer:
4.063 x 104
Step-by-step explanation:
Why is 40,630 written as 4.063 x 104 in scientific notation?
If it helps, y = x can be written as y = 1x + 0.....here ur slope is 1. A parallel line will have the same slope
y = mx + b
slope(m) = 1
(2,4)...x = 2 and y = 4
now we sub and find b, the y int
4 = 1(2) + b
4 = 2 + b
4 - 2 = b
2 = b
so ur parallel equation is : y = x + 2
I think it is 1.5, sorry if i'm wrong good luck!!!

Moving to the edges it travels 2*3 + 2*2 = 10 units.
Then it moves in a circular path when it turns the 4 corners.
It goes through 90 degrees in each case - or pi/2 units
so 4 turns = 4 * pi/2 = 2 pi units
Answer is 10 + 2 pi.
