75 - 12x^2 = 3(25 - 4x^2)
We conclude that the interval in which the function decreases is (1.5, 3]
<h3>
In which interval is the ball's height decreasing?</h3>
The ball is decreasing when the graph, reading from left to right, is going downwards.
Particularly, in this parabola that opens downwards, the graph will decrease after the vertex.
And we can see that the vertex is at x = 1.5
And we also see that the graph of the function ends at x = 3.
Then we conclude that the interval in which the function decreases is (1.5, 3]

Hey there!
The answer to your question is a = s - b - C/2
<u>To solve for "a", we must get "a" on it's own side of the equal sign.</u> We can first subtract "s" from both sides:
<em>0 = a + b + C/2 - s</em>
Then, we can subtract a from both sides:
<em>-a = b + C/2 - s</em>
Finally, we divide both sides by -1, so a is by itself.
<em>a = -b - C/2 + s</em>
And we can rearrange it to the standard form:
a = s - b - C/2
Good luck, and hope it helped! Have a great day!
