For this case we must find the domain of the following function:

By definition, the domain of a function is given by all the values for which the function is defined.
In this case, the argument of the expression must be greater than 0 to be defined.

Thus, the domain of the function is given by all the values of x greater than -2.
Answer:
Domain: 
The speed of the 747 jet is 545MPH and the speed of the 787 jet is 530MPH. that means the 747 jet is faster by 15MPH
8 x 4 x 2 = 64
Therefore the volume of the pond is equal to 64m³
4/5 - 7/9 + 1/5
(4/5 + 1/5) - 7/9
1 - 7/9
9/9 - 7/9
2/9 <==
36, 3.6, 0.36, 0.036 is the order
