move the decimal point 2 places to the left
42.6 / = 0.426
1. It is parallel to the x-axis.
We have that
the first balance indicates--------> 10 g
the second balance indicates--------> 0 g
the third balance indicates--------> 7.5 g
therefore
the <span>mass of the chick is (10+0+7.5)----> 17.5 g
the answer is
17.5 g</span>
Answer:
a) b) (a,b) (c, d) As long as (a,b) and (c,d) are the endpoints of of the diameter.
Step-by-step explanation:
a)
1) The reduced formula of the Circumference is given by:
2) Let's expand the factored one into one closer to the pattern above:
3) Completing the square for both trinomials:
4) In the Reduced Formula, ,
b) Using the previous example to show this:
When we factor this way
We are indeed, naming "a" and "b", the coordinates of (a, b) of the first endpoint and "b" and "d" the second endpoint as well.Id est, D (2, 5) and B (6,-11).
The radius, is
So yes, the equation of the circle can be written as
As long as (a,b) and (c,d) are the endpoints of of the diameter.
