Answer:
y=11
Step-by-step explanation:
your slope when you use y2-y1
---------
x2-x1
will become -12/0 so the equation will be y=11
13/52= 1/4 or .25
If you have a scientific calculator it really helps with simplifying numbers to the lowest term.
Answer:
sin²Ф
Step-by-step explanation:
I doubt that you actually meant "cos 0" ... that has a value of 1.

That, in turn, is equal to sin²Ф
It has a surface area to volume ratio of 1:1
