Circumference of circular path=pi*d^2/4
=44.156
length of light=1.45
light needed=44.156/1.45
=31 approx
I think the best property to use is electronegativity since that is how much it attracts/wants electrons. The larger the difference in electronegativity is between two atoms, the stronger the ionic bond will be. This is also why two atoms need to have a minimum difference between the electronegativity to be considered ionic and not covalent.
Y=x+5
Let's say we are given that x is equal to 5.
Thus, since x=5, we can <em>replace</em> x with the number 5.
So instead of y=x+5, we now have:
y=5+5=
Another example:
x=4+y
where y= 2
x=4+2
Answer:
Step-by-step explanation:
If the coordinates are (0, a) and (b, 0), we just use the distance formula to find the distance in terms of a and b:
and
which simplifies to

and that's it!
