a.![dV = 3x^2\ dx](/tpl/images/1010/5894/3fa0d.png)
b. See Explanation
Step-by-step explanation:
Given
Shape: Cube
Solving (a); Formula that estimates the change in edge length
The volume (V) of a cube is:
Where
The change in volume is got by:
Differentiate![x^3](/tpl/images/1010/5894/b7cd4.png)
Where
Solving (b):
The initial and final edge lengths are not given.
In order to solve this question, I'll assume that x changes from 5cm to 5.01cm
So, we have:
Substitute these values in![dV = 3x^2\ dx](/tpl/images/1010/5894/3fa0d.png)

Andrea can only buy 1 snack
Okay so since she had 18 dollars at first write it down. So now,you would write down $18 and then Andrea spent $6.50 on a notebook. write that down as well. so now you do $18 - $6.50. that equals $11.50. but Andrea needs to save $5.75. so, subtract that from the $11.50 that you wrote $6.50. write $18-$6.50=$11.50 okay so now that you have that $11.50 written down, subtract 5.75 (for Andrea's savings) and then $11.50 - $5.75 = $5.75. So she can only buy 1 snack.
