How should you write the proportion 9:36 = 10:40 using words?
A. 9 is to 36 as 40 is to 10
B. 9 is to 10 as 36 is to 40
C. 36 is to 9 as 10 is to 40
D. 9 is to 36 as 10 is to 40
Answer:
It is not. Also use ^2 to represent squaring a number.
Step-by-step explanation:
First, USE ^2 FOR SQUARED
It is not correct.
The standard equation of a circle is (x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius.
In your question the center is (-2,3) and the radius is the length of the line segment from the center to any pointon the circle. nd hey, it tells us a point on the circle is (-2,6).
Let's take it one part at a time. we know h and k so let's plug them in.
(x-h)^2 + (y-k)^2
(x-(-2))^2 + (y-3)^2
(x+2)^2 + (y-3)^2
now r is the length of the line segment from (-2,3) and (-2,6). To get from (-2,3) to (-2,6) hopefully it is pretty obvious you just move up (so int he y direction) 3 spaces. this makes r = 3. int he formula we want r^2 and that is 9. The result is that the circle has a formula of:
(x-h)^2 + (y-k)^2 = r^2
(x+2)^2 + (y-3)^2 = 9
The formula Juanita got is actually a hyperbola.
Answer:
Option B
Step-by-step explanation:
From the figure attached,
Circle D is drawn with the radius = DG or DE
A tangent FG has been drawn at a point G on the circle from an external point F.
By theorem,
Radius of a circle is always perpendicular to the tangent, drawn to the circle from an external point.
Therefore, DG ⊥ FG.
Option B will be the correct option.

Step-by-step explanation:
Here 3x-12y-216=0
Reducing into slope intercept form
-12y= -3x + 216
12y = 3x - 216
Which is in the form of, y = mx + c
Slope (m) = 3
