olga nikolaevna [1]

It might be helpful to write up the question like this:
300=100%
3=1%
120=

If you do this, you’ll see that the question is really easily solved by just finding the number necessary to multiply 3 with to get 120.

If you understand this, the rest should follow.

Lf f(x) = 5x, what is f^-1(x)?

Nonamiya [84]

Answer: $f^{-1}(x)=\frac{x}{5}$

Step-by-step explanation:

By definition the domain of an inverse function $f^-1(x)$ is the range of f(x) and the range of the inverse function is equal to the domain of the principal function f(x).

If you have a function $f(x)=5x$ , then to find the inverse function, follow these steps:

1. Make $y=f(x)$

$f(x)=y=5x$

$y=5x$

2. Solve for the variable "x":

$x=\frac{y}{5}$

3. Exchange the variable "x" with the variable "y":

$y=\frac{x}{5}$

4. Exchange "y" with $f^{-1}(x)$ . Then the inverse function is:

$f^{-1}(x)=\frac{x}{5}$

Temka [501]

Using the slope concept, it is found that the rate of download of the file is of 1920 MB/s.

<h3>What is the slope?</h3>

The slope of a linear function is given by the <u>change in the output divided by the change in the input</u>.

In this problem:

3 minutes since resuming the download 6720 total MegaBytes (MB).

5 minutes since resuming the download 10560 total MegaBytes (MB) of the file had been downloaded..

Hence, in 2 minutes, there was a change of 10560 - 6720 = 3840 MB, which means that the slope is:

$m = \frac{3840}{2} = 1920$

The rate of download of the file is of 1920 MB/s.
