<span>The cosine of pi/2 is 0 so the problem really says "find the angle between - pi/2 and pi/2 whose tan = 0. That would be the same as asking for the angle whose sin is 0. That would be 0.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:

The angle is 0°.

Step-by-step explanation:

Consider the provided trigonometric function.

$tan^{-1}(cos\frac{\pi}{2})$

The given interval $[\frac{-\pi}{2}, \frac{\pi}{2}]$

The value of $cos\frac{\pi}{2}=0$

Now substitute the respective value in the provided trigonometric function.

$tan^{-1}(tan(0))=0$ by inverse property of trigonometric function

Hence, the angle is 0°.

I'm assuming you mean he earns $8.75 an hour.

So first we have to find out how much money Mark gets without any commission. We do this by multiplying 30 and 8.75 and getting $262.50 .

Then, we have to find the commission. 5% as a decimal is .05, and in order to get 5% of a number, we multiply the 5% and the number together. In other words, we now have to multiply .05 and 480 together, which results in 24.

In conclusion, as a total salary, Mark earns $262.50 + $24, or $286.50
