Answer:
Vertex: (-2, 2)
Step-by-step explanation:
The x-coordinate of the vertex would be as follows;
x = -b/2a = 8/2(-2) = -8/4 = -2
respectively the y-coordinate of the vertex would be y(-2) = -2(-2)^2 - 8(-2) - 6 = -2(4) + 16 - 6 = - 8 + 10 = 2
Your vertex would be a maximum of (-2, 2)
* I say maximum as the coefficient of x^2 is -2, and it is less than zero so the parabola opens downward
circumference = 3.14 * diameter
circumference = 3.14 * 4.79 ft
circumference = 15.0406 ft
Answer:
The point lies outside the circle.
Step-by-step explanation:
<u>To find where the point lies find the distance between the centre of the circle and the point :</u>
<u /><u />
Since distance between Centre, Q and the point, Y is greater than the radius of the circle , the point lies outside the circle.
