The equation of the vertical parabola in vertex form is written as
Where (h, k) are the coordinates of the vertex and p is the focal distance.
The directrix of a parabola is a line which every point of the parabola is equally distant to this line and the focus of the parabola. The vertex is located between the focus and the directrix, therefore, the distance between the y-coordinate of the vertex and the directrix represents the focal distance.
Using this value for p and (3, 1) as the vertex, we have our equation
Answer:
Sample size minimum is 60
Step-by-step explanation:
given that you want to create a 99% confidence interval with a margin of error of .5.
The population standard deviation is equal to 1.5
i.e.
Confidence level = 99%
Since population std deviation is known, we can use Z critical value for finding margin of error
Z critical value for 99% = 2.58
Margin of error =
Equate this to 0.5 and solve for n
Answer:
A) The point( -1 , 5) is satisfies the given graph
B) The point( 3 , 1/125) is satisfies the given graph
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given graph
y =
Put the point ( -1 , 5)
Put y =5 and x =-1
The point( -1 , 5) is satisfies the given graph
ii)
Given graph
y =
