The trigonometric form of the complex number given in the task content is; 18(isin(π/2)).
<h3>What is the trigonometric form of the complex number?</h3>
If follows from the task content that the complex number whose trigonometric representation is to be determined is; 18i.
Hence, It follows that the trigonometric form is;
= 18(cos(π/2) + isin(π/2)). where; cos(π/2) = 0.
Hence, we have;
= 18(isin(π/2)).

An item is regularly priced at $30. It is on sale for 20% off the regular price. How much in dollars) is discounted from the regular price?
Ok so first off you need to get rid of the clauses in the equation.
So 4.5 ( -4) becomes -18 and -2.5(3+28) becomes -77.5
-18 + 36 = 202 - 77.5
Now you are going to solve the equation.
18 = 122.5
Hope this helped ;),
