One revolution corresponds to an angular displacement of , so its angular speed is
radians is equivalent to 180 degrees, so the angular speed could also be
The linear speed depends on the wheel's radius. Suppose its radius is . Then the wheel has circumference units. A point on the edge of the wheel travels this distance in one revolution, so its linear speed is
(where stands for units of length)
Answer:
Step-by-step explanation:
From the information given :
The objective is to find the demand function which is expressed in p, the price in dollars charged for each ticket, as a function of x, and the number of average attendance is:
Suppose the admission price P = D(x) = 30 and number of average attendant = x = 800 people
Then:
ΔP = -1
Δx = 20
According to point line form :
where the point is (30, 800)
∴
x - 800 = -20 (P - 30)
x - 800 = -20P + 600
collect like terms
x + 20P = 800+ 600
x + 20P = 1400
x = 1400 - 20P
Thus, price in dollars for each ticket P = D(x) is:
