Given:
The height of a golf ball is represented by the equation:
To find:
The maximum height of of Anna's golf ball.
Solution:
We have,
Differentiate with respect to x.
For critical values, 
.
Differentiate y' with respect to x.
Since double derivative is negative, the function is maximum at .
Substitute in the given equation to get the maximum height.
Therefore, the maximum height of of Anna's golf ball is 6.25 units.
Answer:
The total income of designer from this work is $1649.6.
Step-by-step explanation:
The fees charged by the designer = $1600
The commission on total sales = 8%
Total sales amount in the festival = $620
Now, 8% of $620 = 
So, the commission on total sales = $49.6
Also, Total Income of the designer = Deign Fee + 8% Commission fee
= $1600 + $49.6
= $1649.6
Hence, the total income of designer from this work is $1649.6.

Answer:
225 centimeters.
Step-by-step explanation:
To solve this, we need to find half of 4.5. We can do this by dividing 4.5 by 2. When we do this, we get 2.25. This means Noah's plane flew 2.25 meters, but we aren't done yet. Now, we need to find how much farther Aaron's plane flew. We can do this by subtracting 2.25 from 4.5. From this, we get 2.25. That last step wasn't really necessary. Now, we need to convert 2.25 meters to centimeters, we can do this by multiplying 2.25 by 100. When we do this, we get 225. This means Aaron's plane flew 225 centimeters farther than Noah's plane.
