Answer:
δhsoln will be close to zero.
Step-by-step explanation:
In calculus, the symbol d represents a large or significant increment in a value. For example, say the change in the volume of a liquid in a tank depends upon the change of the height h.
The above statement can be written like this:
dV/dh
This means that the volume of the tank (V) depends with a significant change in the height of the liquid (h).
It is also possible to compute small changes in physical quantities. The symbol δ simply presents a small increment or small change. Using the same expression above, if a very large tank was to have a very very small leak, the change would be: δV/δh
In other words, the change in the volume will be almost negligible and will be close to zero.
Add parentheses around 12 - 2.
Add parentheses around 2 + 2.
Add parentheses around 22 ÷ 8.
Nothing needs to be done.
Nothing can be changed in order to equate the expression to 10.
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is the following expression -
12 - 2 + 22 ÷ 8
[A] : {12 - 2} + 22 ÷ 8
10 + 22 ÷ 8
10 + 2.75 ≠ 10
[B] : 12 - {2 + 2}2 ÷ 8
12 - 4 x 2 ÷ 8
12 - 4 x 2 x 1/8
12 - 4 x 1/4
12 - 1
11 ≠ 10
[C] : 12 - 2 + {22 ÷ 8}
12 - 2 + 2.75
12 + 0.75
12.75 ≠ 10
Therefore, nothing can be changed in order to equate the expression to 10.

To determine the length and width of a rectangle, we can set up an equation using the given information and solve for the variables. By substituting the width back into the equation for the length, we find that the width is 9 meters and the length is 13 meters.
To solve this problem, we can start by using the given information to create equations. Let's assume that the width of the rectangle is 'w' meters. According to the problem, the length of the rectangle is 5 meters or less than twice the width, so the length can be represented as 2w - 5 meters.
The formula to calculate the perimeter of a rectangle is 2l + 2w, where 'l' is the length and 'w' is the width. We are given that the perimeter is 44 meters, so we can set up the equation as follows:
2(2w - 5) + 2w = 44
Simplifying the equation, we get:
4w - 10 + 2w = 44
Combining like terms, we have:
6w - 10 = 44
Next, we can isolate the variable by adding 10 to both sides:
6w = 54
Finally dividing both sides by 6, we find that:
w = 9
Therefore, the width of the rectangle is 9 meters. Substituting this value back into the equation for the length, we find:
l = 2w - 5 = 2(9) - 5 = 18 - 5 = 13 meters.
