The expression that represents the profit is: ( 5x2 + 2x – 80)-(<span>5x2 – x + 100)
Profit can be modeled by polynomial expression: 3x-180
If 1,000 video game systems are sold, the company's profit is: $2,820</span>
We use the trigonometric function for this case. An escalator is an inclined path. We form a right triangle since we have given the value of the height. The height from the first floor to second floor is called the adjacent while the travelled distance of the people is called the hypothenuse. We use cosine function because we are given in terms of adjacent and hypothenuse. The ratio of cosine function is
cos x = a/h
where x is the angle
Solving for h,
h = a/(cos x) = 21/(cos 30) = 24.25 ft
