Answer:
12
Step-by-step explanation:
2x (3) = 72 so 6x = 72 and so x = 12
Answer:
Minimum
Step-by-step explanation:
The zeros of a quadratic equation are the points at which the parabola intersects the x-axis.
(for some constant a)
The optimal value is the <u>y-coordinate of the vertex</u>.
The x-coordinate of the vertex is the midpoint of the zeros:
Therefore, the vertex will be in Quadrant IV and so the parabola opens <em>upwards </em>into Quadrant I.
So the optimal value is a MINIMUM since the vertex is the minimum point of the curve.
<u>Additional Information to create the equation of the quadratic</u>
Vertex form of quadratic equation:
where (h, k) is the vertex
To find the value of a, compare the constants of both equations:
So the final equation is:
36 inches = 1 yard
1 inches = 1/36 inches
so 46 inches = 46 * (1/36) yard
46 inches = 46/36 which is approx. 1.28 yard
