Answer:
1 circle
Step-by-step explanation:
Given two circles (red circles on the diagram).
There are two tangent circles to both of the given circles (blue circles on the diagram), and only one of them is passing through the point (0,5).
Let's check it.
The equations of the tangent circles are
![x^2+y^2=9\ [\text{Smaller tangent circle}]\\ \\x^2+y^2=25\ [\text{Larger tangent circle}]](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D9%5C%20%5B%5Ctext%7BSmaller%20tangent%20circle%7D%5D%5C%5C%20%5C%5Cx%5E2%2By%5E2%3D25%5C%20%5B%5Ctext%7BLarger%20tangent%20circle%7D%5D)
Check whether point (0,5) lies on the smaller circle:
No
Check whether point (0,5) lies on the larger circle:
Yes
<u>Answer: </u>1 circle
I believe it’s D because the notation should be outside the parenthesis
Answer:
the original area is 64ft squared or 169ft squared more perdurable 64
Step-by-step explanation:
(x-2)(x+7)=90
x^2 +5x -14=90
x^2 +5x -14 -90=90-90
x^2 +5x -104=0
factor it out
(x−8)(x+13)=0
so 8 or -13
I don’t know what the answer options are so here I go guessing:
M<4 is the opposite but has the same degree
M<6 is the same as M<2
M<8 is the opposite but has the same degree
Any of these are correct. I’m just not sure what the options were/are.
