Step-by-step explanation:
Answer:
2 1/9
Step-by-step explanation:
Divide 19 by 9 and get a number with a remainder
Take remainder and put it as the numerator with 9 and the denominator and with 2 as the whole number
There is no quotient: if x is equal to zero, then your problem would simplify to a number divided by zero. As it is impossible to divide by zero, there is no answer.
Answer:
Lest then 5/8
Step-by-step explanation:
Lest then 5/8
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.
