Perhaps the most successful way we've been able to use light to transfer information is fiber optics. ... Through rapid changes in the light, you can send highly complex signals down the cable. These are most often used either for high speed internet connections, or for sending sound signals to home theater systems.

Explanation:

Because these two waves are traveling through the vacuum of space, they all travel at the speed of light (the fastest speed in which information could be transmitted) within the electromagnetic spectrum.

Write a short speech that persuades students and parents to choose the bake-sale fundraiser instead of the car-wash fundraiser.

alexgriva [62]

Answer:

I think the bake sale would be better because, if one we're to do a car wash they may not know how to wash a car and selling baked goods is WAY easier than a car wash. A car wash can be bad depending on the weather and the bake sale. So I would chose the bake sale, it's easier, faster and much more.

5) Futures Contracts are highly standardized whereas the terms of each Forward Contract can be privately negotiated. Futures are traded on an exchange whereas forwards are traded over-the-counter.

Below is the graph of f ′(x), the derivative of f(x), and has x-intercepts at x = -3, x = 1 and x = 2. There are horizontal tang

Answer:

1. f has an inflection point at x = -1.5

Explanation:

Let's analyze each statement given.

1. f has an inflection point at x = -1.5 --> TRUE

An inflection point is a point in which the function f(x) changes concavity: this means that the first derivative of a function has a relative minimum or maximum, and therefore the second derivative is zero, $f''(x_0)=0$ .

In this case, we see that at the point

x = -1.5

The first derivative is flat: this means that at this point, the second derivative is zero, so this is an inflection point.

2. f is increasing on the interval from x = -3.2 to x = -4.5. --> FALSE.

We simply don't know this: in fact, we cannot see the graph of the derivative between -4.5 and -3.2, therefore we don't know if the function is increasing or not.

3. f has a relative minimum at x = 1.5 --> FALSE.

A function $f(x)$ has a relative minimum at a point $x_0$ if the first derivative $f'(x)$ is zero at that point:
