Select the graph that represents the equation x^2 + (y-4)^2=2.25
1 answer:
Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
The equation of a circle into center radius form is equal to
where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have
therefore
the center is the point
the radius is
using a graphing tool

Answer:
This tells us that:
Step-by-step explanation:
So we are saying we have scalars, c and d, such that:
.
So we want to find a way to express this as:
Ax=b where x is the scalar vector, .
So we can write this as:
The perpendicular bisector theorem gives the statements that ensures
that and
are perpendicular.
The two statements if true that guarantee is perpendicular to line
are;
Reasons:
The given diagram is the construction of the line perpendicular to line
.
Required:
The two statements that guarantee that is perpendicular to line
.
Solution:
From the point <em>C</em> arcs <em>E</em> and <em>D</em> are drawn to cross line , therefore;
arcs drawn from the same radius.
is perpendicular to line
, given.
Therefore;
by perpendicular bisector theorem.
