The height attained by an objects thrown from ground level is given by the equation:
At maximum height, v = 0, we assume
then we have:
Therefore, the <span>minimum speed that the stone should be thrown so as to reach a height of 49 feet</span> is 56 feet per second.
The GCF is 1
Hope his helped

Answer:
The positions of the vertex and the axis of symmetry change.
Step-by-step explanation:
Let’s examine three parabolas in which a and c remain constant and only b changes.
(1) y = x² - 2x + 1
(2) y = x² + 1
(3) y = x² + 2x + 1
In the image below,
Equation (1) is the black parabola, Equation (2) is green, and Equation (3) is red.
When b is more negative, the vertex moves down, and the axis of symmetry moves to the right.
When b is more positive, the vertex moves down, and the axis of symmetry moves to the left.
