On a certain route, an airline carries 8000 passengers per month, each paying $50. A market survey indicates that for each $

Jobisdone [24]

Answer:

$65
$424500

Step-by-step explanation:

Let x be the price increase.

Then the current price is:

50 + x

Then the number of passengers is:

8000 − 100x

Then the revenue:

Revenue = Price * Number of Passengers
R = (50 + x)(8000 − 100x) =
- 100x² + 3000x+ 400000

This is a quadratic relationship. Maximum point is obtained at vertex.

Vertex is determined by x = - b/2a, find the value of x:

x = - 3000 / (-2*100) = 15

The maximum revenue is:

R = (50 + 15)(8000 − 100 * 15) = 424500

Why is trigonometric form of a complex number not unique

MrMuchimi

because in trigonometric form, the argument can take on multiple values due to the nature of trigonometry

for example, we have coterminal angles.

sin(30) + cos(30) is the same as sin(30+360n) + cos(30+360n), where n is an integer.
