A ferris wheel can accommodate 55 people in Twenty minutes. How many people can ride the ferris wheel in 3 hours? What was the r
DerKrebs [107]

1 hour = 60 minutes.

60 minutes / 20 minutes = 3.

55 people x 3 = 165 people per hour. (Rate per hour)

165 people x 3 hours = 495 people. (Total people in 3 hours)

The price p (in dollars) and the quantity x sold of a certain product obey the demand equation:
katen-ka-za [31]
X = -20p + 500
20p = 500 - x
p = (500 - x)/20

R = xp = x(500 - x)/20 = (500x - x^2)/20

Is (x-1) a factor of 2x3 - 15x2 + 22x + 15
Advocard [28]

Answer:

Step-by-step explanation:

If x - 1 is a factor of the cubic, then 1 should result in 0 when you put it in the cubic for x. Does it?

f(1) = 2(1)^3 - 15(1)^2 + 22(1) + 15

f(1) = 2 - 15 + 22 + 15

f(1)= 24.

No the result is not zero. So x - 1 is not a factor.

However there must be something that makes this cubic go to zero. The easiest way to find it is to graph it.

The numbers that do make this zero are -0.5, 3, 5

Which mean that the factors are (2x+1)(x-3)(x - 5)
