The answer is A. So 25,700+3,000+700= 29,450. Then you subtract 29,450-6000= 23,450. So then A is your answer.
I hope this helps you. :)
Answer:
I’m gonna explain this best I can
Step-by-step explanation:
okay, since I dont have graphing paper or your graph, I am going to put the points that your dots would go in, and you can put them and connect the line :)
first point: (0, -1)
second point: (7, 4)
third point: (14, 9)
then connect the line
I assume that the parabola in this particular problem is one whose axis of symmetry is parallel to the y axis. The formula we're going to use in this case is (x-h)2=4p(y-k). We know variables h and k from the vertex (1,20) but p is not given. However, we can solve for p by substituting values x and y in the formula with the y-intercept:
(0-1)^2=4p(16-20)
Solving for p, p=-1/16.
Going back to the formula, we can finally solve for the x-intercepts. Simply fill in variables p, h and k then set y to zero:
(x-1)^2=4(-1/16)(0-20)
(x-1)^2=5
x-1=(+-)sqrt(5)
x=(+-)sqrt(5)+1
Here, we have two values of x
x=sqrt(5)+1 and
x=-sqrt(5)+1
thus, the answers are: (sqrt(5)+1,0) and (-sqrt(5)+1,0).
Well for each pair of x and y value of the table, you can always find the coordinates of that point on the graph.
eg. x=y=-2 you can find the point {-2,-2} on the graph
Answer:
A
Step-by-step explanation:
Okay cool, so basically the formula is a^2 + 2a square root a square over 4 + h square.
We have to us e the Pythagorus theorem to find the height.
3^2 + h^2 = 36
9 + h^2 = 36
h^2 = 27
h ~ 5
Let's plug in the values from the formula.
The closet answer should be A
