Answer:
12/18
Step-by-step explanation:
4/9 = 0.4444....
12/18 = 2/3 = 0.66666....
"Inversely" generally means the relationship is proportional to the reciprocal.
y = k/x
Answer:
Step-by-step explanation:
The choices are all exponentials, the x is raised to a power.
First of all, an exponential in the form:
Where (a > 1)
Would have this shape and it will go through (0,1)
Now, looking at the graph, we see that it is translated 3 units down from (0,1).
The basic graph is and the translated one would be:
<u>NOTE:</u>
Basically is this is vertically translated a units down, the equation becomes:
and if translated a units up, the equation would be:
Answer:
(x + 1)² + (y - 6)² = 50
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius.
The radius is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r =
with (x₁, y₁ ) = (- 1, 6) and (x₂, y₂ ) = (- 6, 1)
r =
=
=
=
(h, k ) = (- 1, 6 ), then
(x - (- 1))² + (y - 6)² = ( )² , that is
(x + 1)² + (y - 6)² = 50 ← equation of circle
