Answer:
To get the real solutions of the quadratic equation from the graph of the equation, we must determine the x-intercepts of the graph.
In this case, the x-intercepts of the graph are:
Therefore, the solutions of the quadratic function are:
By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is
<h3>What is section formula ?</h3>
Let point P(x,y) cuts line joining point and in then coordinate of point P is equal to
Here given that point divides line segment from J to K into a ratio 5:1
So
Now we have to fin y coordinate of point that divides the directed line segment from J to K into a ratio of 5:1
We can calculated y coordinate by applying section formula as :

Answer:
-2 1/3, -5/2, 1/16, 16
The more negative the number gets, the lesser it would be.
a. The first part asks for how many ways they can be seated together in a row. Therefore we want the permutations of the set of 6 people, or 6 factorial,
6! = 6 5
= 30 4
= 360 2 = 720 possible ways to order 6 people in a row
b. There are two cases to consider here. If the doctor were to sit in the left - most seat, or the right - most seat. In either case there would be 5 people remaining, and hence 5! possible ways to arrange themselves.
5! = 5 4
= 20 3
= 120 1 = 120 possible ways to arrange themselves if the doctor were to sit in either the left - most or right - most seat.
In either case there are 120 ways, so 120 + 120 = Total of 240 arrangements among the 6 people if the doctor sits in the aisle seat ( leftmost or rightmost seat )
c. With each husband on the left, there are 3 people left, all women, that we have to consider here.
3! = 3 2 6 ways to arrange 3 couples in a row, the husband always to the left
