Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
step 1
Find the equation of the circle
we know that
The equation of the circle is equal to
where
(h,k) is the center
r is the radius
In this problem we have
and the radius is equal to the distance between the center and the point (-2,4)
so
----> look at the graph
substitute in the equation
step 2
If the distance between the center and the point is equal to the radius of the circle , then the point lie on the circle
the formula to calculate the distance between two points is equal to
substitute the values
therefore
the point lie on the circle
Answer:
x = 98
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles.
x = 53+ 45
x = 98
Answer:
The answer is 0 or 1
Step-by-step explanation:
nobody give you a very long question to solve so I think it has a short solution. When you multiply all equation with together.. after a step it must equal to 0 or 1

Answer:
y = -1/4x^2 -3/2x +3/4
Step-by-step explanation:
You know that vertex form is ...
y = (1/(4p))(x -h)^2 +k
for a focus-vertex distance of p and a vertex of (h, k).
Here, the focus-vertex distance is 2-3 = -1 (difference of y-coordinates), and the vertex is (h, k) = (-3, 3). This means the vertex form equation is ...
y = -1/4(x +3)^2 +3
Expanding the square gives ...
y = -1/4(x^2 +6x +9) +3
y = -1/4x^2 -3/2x +3/4
