The percentage discount will be 9%.
<h3>How to calculate the value?</h3>
From the information given, the item he wants to buy is priced at $13, before discount and tax and after the discount, and before tax, the price is $11.83.

= 1.17/13 × 100
= 9%
Therefore, the percentage discount will be 9%.

Assuming you're asking "for which values of the function has an inverse that is a function", the answer is "all the odd exponents ".
Infact, if is even, you have that
and so is not injective, and thus not invertible
On the other hand, if is odd, we have:
- is continuous.
- The first two points tell us that the function is surjective.
- Moreover, the derivative is . Since is even, we have , thus the function is always increasing, and so the function is also injective.
- Injective and surjective means bijective, and the function can be inverted.
<span>D No, it is not. A straight angle has a measure greater than 90°, but it is not an obtuse angle.
The sentence should say: </span>An obtuse angle is an angle whose measure is greater than 90° but less than 180°
