Answer:

All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1260 degrees (from above)... And there are nine angles... So, the measure of the angle of a regular nonagon is 140 degrees.

The revenue, in dollars, of a company that produces jeans can be modeled by 2x2+17x−175. The cost, in dollars, of producing the
Charra [1.4K]

The expression that can be used to find profit is 20x – 50 and that profit when 75 pairs of jeans are sold is 1,450.

<h3>How find profit function and the profit?</h3>

Let R represents the revenue function and C represents the cost function, the two functions can be stated correctly as follows:

R = 2x^2+17x−175

C = 2x^2−3x−125

Let P represents the expression that can be used to find profit, we therefore have:

P = R – C

P = 2x^2+17x−175 – (2x^2−3x−125)

P = 2x^2+17x−175 – 2x^2 + 3x + 125

P = 2x^2 – 2x^2 + 17x + 3x – 175 + 125

P = 20x – 50

The profit when 75 pairs of jeans are sold can therefore be calculated as follows:

P = (20 * 75) – 50

P = 1,450
