This passage is about the domain of a function. The domain of a function is the set of all points that you can give to the function as an input.
Points not belonging to the domain are not good inputs for the function. In this example, 3 is not a good input, because if you try to evaluate the function at , i.e. if you plug 3 in place of x, you get
which is undefined, because you can't divide by 0.
So, when defining this function, you have to specify , so that the function will be defined for every other input.
Answer:
80 feet
Step-by-step explanation:
Let x represent the height of the pole.
We have been given that a telephone pole has a wire attached to its top that is anchored to the ground. The distance from the bottom of the pole to the anchor point is 41 feet less than the height of the pole. So the distance between bottom of pole to the anchor point would be .
The wire is to be 9 feet longer than the height of the pole, so length of the wire would be .
We know that length of the wire would be hypotenuse of right triangle, so we can use Pythagoras theorem as:
Since the distance from the bottom of the pole to the anchor point is 41 feet less than the height of the pole, so 20 feet cannot be height of the pole.
Therefore, the height of the pole is 80 feet.
Answer: 20%
Step-by-step explanation:
There are 15 total cookies. Divide 3 by 15, 3 being how many cookies he took out. Then you get 0.2. Move the decimal over two and you have 20%.
