Given that the graph of the quadratic function.
We need to determine the vertex of the graph and also determine whether it is a minimum or maximum value.
<u>Vertex:</u>
The vertex of the parabola is the point at which the parabola makes a turn to form a U - shaped graph.
Hence, from the figure, the parabola turns at the point (0,-2) to form a U - shaped graph.
Therefore, the vertex of the graph is (0,-2)
<u>Minimum or maximum value:</u>
When the parabola is open upwards, then the vertex is the lowest point on the graph which is the minimum value on the graph.
Thus, the graph has a minimum value.
Hence, the vertex of the graph is (0,-2); minimum value.
Therefore, Option A is the correct answer.
Answer:
The Regression line is that line , which passes through all the points , through a single point , or none of the points.
Here, the table is about ,weight of a dog in pounds at various ages in months.
The ratio of Weight at different stages,of months should be proportional.
So, if you look at option (1) , the ratio of x to y in three cases are same that is

It means Regression line is Passing through three points, means Dog's weight at three different stages of month are same.and in other tables the ratio are not equivalent.
So, Table 1, that is option 1
is true.
x: 3, 4, 6, 8, 9, 12
y: 2, 5, 7, 10, 11, 15
Answer:
14.2 ft
Step-by-step explanation:
tan 66° = 32/ FD
FD = 32 / tan 66° = 32 / 2.246 = 14.2
