Answer:
f(x) = x(x-1)
Step-by-step explanation:
The easy way to do this is to look at it graphically. an inverse function is reflected across the line y=x. f(x)=x(x-1) is an upward opening parabola when reflected, there are two y-values for all positive values of x. A function can only have one y for every x.
Answer:
2/3
Step-by-step explanation:
greater than 2: 3, 4, 5, and 6
4/6=2/3
Answer and Step-by-step explanation:
This problem requires the use of trigonometric functions, specifically the tangent trig function.
![tan(Angle)=\frac{opposite}{adjacent}](https://tex.z-dn.net/?f=tan%28Angle%29%3D%5Cfrac%7Bopposite%7D%7Badjacent%7D)
Plug in the values.
![tan(40) = \frac{8000}{x}](https://tex.z-dn.net/?f=tan%2840%29%20%3D%20%5Cfrac%7B8000%7D%7Bx%7D)
Multiply by x to both sides, then divide by tan(40) to both sides.
![x = \frac{8000}{tan(40)}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B8000%7D%7Btan%2840%29%7D)
Now, plug this into a calculator and rounded to the nearest whole number (foot).
x = 9534.0287
x = 9534 ft.
The answer is 9534 ft., the last option.
