Answer:
Step-by-step explanation:
You have a vertex coordinate and 2 points. In order to write the equation for that parabola, you only need the vertex and one point. We will fill in the following work form of the parabola:
, where h and k are from the vertex and x and y are from the point. Filling in:
and
and
and
9 = 9a s0
a = 1.
Now we can write the equation, filling in a, the only unknown we had, which we now know is 1:
So in order for us to come up with the right equation, let us analyze the given problem first.
So the total number of people on the trip is 82.
The number of children under 12 is 54. Which makes the number of people over 12 is 28.
The number of children under 3 is x.
And c <span>represents the total amount of money collected from tickets that day.
</span>So based on this, we can say that the equation would be:
C = 28(44) + (54-x)32
I hope that answer helps. Let me know if you need more help next time. Thanks for posting your question.
X^2 + 4y^2 - 6x = 7
x^2 - 6x + 9 + 4y^2 = 16
(x-3)^2/16 + y^2/4 = 1
The graph is an ellipse
hope this helps
