Answer:
<em>E) bounded from both above and below.</em>
Step-by-step explanation:
<u>Sequences</u>
The given sequence is
To obtain the terms of the sequence, we give n values from the natural numbers set, i.e.
The sequence is expanded as
Now we must recall some of the properties of the sine function: it's periodic and bounded from a minimum value (-1) to a maximum value (1), that is
Thus, the correct answer is
E) bounded from both above and below.
Here is the equation:
You need to find f(3). To do that, substitute all the x's with 3:
The first thing you need to do is multiply 4 by 3. Multiply:
Here is your new equation:
To get your answer, you need to add 12 and 1. Add:
That means:

Answer:
Step-by-step explanation:
Let the time flown by the flying carpet be . Then, we have that
.
We multiply both sides of the equation by to get
.
We subtract from both sides to get
.
We divide both sides of the equation by .
We know that the speed of the flying carpet in still wind is the average of the rates of the speed of the flying carpet with the wind and against the wind.
The speed with wind is mph.
The speed against wind is mph.
The speed in still wind is .
Therefore, the answer is and we're done!
