Answer:
I think it's C
Step-by-step explanation:
just looked online.
TIP:
If you want to remember this law,just solve a bunch of questions that involve it and then it will come naturally to you.
The roots, zeros, or solutions (they all means same thing) of an equation are when you graph that equation, x-intercepts are the real roots, zeros, or solutions.
Or set the y equal to zero which does the same job.
The answer to the question is b
(√200/√5)= √40= √4*10= 2√10
Consider we need to find the equation of the circle.
Given:
The Center at (-4,-1), radius = 2.
To find:
The equation of the circle.
Solution:
The standard form of a circle is
Where, (h,k) is the center of the circle and r is the radius of the circle.
Putting h=-4, k=-1 and r=2, we get
Therefore, the equation of the circle is .
Well using distance formula we get the length of ab to be 3, knowing a'b'=6 we know the dilator must be 2
