Since the area of the walkway is not given, it's substitution in the answer is x. You do have the measurements of the pool though. Area=length times width. 36 times 18 is 648. The area of the concrete is x-648 ft, because the pool is not apart of the concrete. The area of the walkway can be expressed by X-648 ft.
70,000
The 0 means that it stays the same.
Hope it helps.
The height of the pole = 129.3 ft
sin 36° = height of pole/ hypotenuse
hypotenuse = 220 ft
the height of the pole = 220 sin 36° = 129.3 ≈ 129 ft
2.6 and 2.4. they are the decimals next to 2.5
The answer is x bc when you decreasing the interval f(x) it will equal (-2)
