Answer:
The vertex and the axis of symmetry in the attached figure
Step-by-step explanation:
we know that
The equation of a vertical parabola written in vertex form is equal to
where
a is the leading coefficient
(h,k) is the vertex of the parabola
and the equation of the axis of symmetry is equal to the x-coordinate of the vertex
In this problem
we have
This is a vertical parabola written in vertex form open upward
The vertex is a minimum
where
the vertex is the point (5,-7)
the x-coordinate of the vertex is 5
so
the equation of the axis of symmetry is equal to
The graph in the attached figure
Answer:
The fraction that express the weight patient has lost is .
Step-by-step explanation:
Given:
Weight of patient on admission= 50 lbs
Weight of patient on day 3 of his hospital stay = 48 lbs
We need to write the fraction reduced to lowest terms, to express the weight he has lost.
Solution:
First we will find the total weight lost.
total weight lost can be calculated by subtracting Weight of patient on day 3 of his hospital stay from Weight of patient on admission.
framing in equation form we get;
total weight lost =
Now we will find the fraction of weight he has lost.
To find the fraction of weight he has lost we will divided total weight lost from Weight of patient on admission.
framing in equation form we get;
fraction of weight he has lost =
Reducing it in lowest term we get;
fraction of weight he has lost =
Hence the fraction that express the weight patient has lost is .
