Which number is written correctly in scientific notation? 1) 0.459×10^8
2) 25.6×10^12
3) 3,892× 10^7
4) 5.03×10^11​

1)4.59 *10^7

2)2.56 *10 ^13

3)3.892 *10 ^10

4)5.03 *10 ^11

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

i suppose it should be (y=2x-5)
