Step-by-step explanation:

$\sin^2 (\frac{\pi}{4} - \alpha) = \frac{1}{2}(1 - \sin 2\alpha)$

Use the identity

$\sin^2 \theta = \dfrac{1 - \cos 2\theta}{2}$

on the left side.

$\dfrac{1 - \cos [2(\frac{\pi}{4} - \alpha)]}{2} = \frac{1}{2}(1 - \sin 2\alpha)$

$\dfrac{1 - \cos (\frac{\pi}{2} - 2\alpha)}{2} = \frac{1}{2}(1 - \sin 2\alpha)$

Now use the identity

$\sin \theta = \cos(\frac{\pi}{2} - \theta)$

on the left side.

$\dfrac{1 - \sin 2\alpha}{2} = \frac{1}{2}(1 - \sin 2\alpha)$

$\frac{1}{2}(1 - \sin 2\alpha) = \frac{1}{2}(1 - \sin 2\alpha)$

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.
