The cost to ride a ferris wheel is $2.00 per person. The ferris wheel has a capacity of 64 people. The amount of money collected

Stella [2.4K]

Answer:

The ferris wheel has a maximum capacity of 64, the domain is [0,64]

Step-by-step explanation:

Given in the question that,

the maximum number of people that can seat on the ferris wheel = 64

the minimum number of people that can seat on the ferris wheel = 0

Function to calculate the amount of money

M(p)=2p

Value of p can be any integer from zero to 64 so the domain of this function is

0 ≤ x ≤ 64

Plz answer quickly!!!!!!!

ValentinkaMS [17]

Answer:

<em>(A). x ≥ </em> $\frac{16}{5}$ <em> and x ≤ - </em> $\frac{3}{4}$ <em> </em>

Step-by-step explanation:

5x - 4 ≥ 12 ⇔ 5x ≥ 16 ⇒ <em>x ≥ </em> $\frac{16}{5}$ <em> </em>

<em>and </em>

12x + 5 ≤ - 4 ⇔ 12x ≤ - 9 ⇔ 4x ≤ - 3 ⇒ <em>x ≤ - </em> $\frac{3}{4}$

A card is drawn from a deck of cards numbered one through twenty. The card is NOT replaced and another card is drawn. Find the p

Bess [88]

Answer:

B) P(two prime numbers are drawn in a row) = 14/95

Step-by-step explanation:

Total cards in the deck = 20

Total prime numbered cards in deck = { 2, 3, 5, 7, 11, 13, 17, 19} = 8 cards

So, Probability of picking two prime cards from deck (without replacing)

= Probability of picking first prime card x Probability of picking second prime card

P( picking first prime card ) = $\frac{\textrm{Total prime cards in the deck}}{\textrm{Total available cards}}$

= $\frac{8 }{20} = \frac{2}{5}$

P( picking second prime card ) = $\frac{\textrm{Total prime cards in the deck}}{\textrm{Total available cards}}$

= $\frac{7}{19}$

Hence, the total probability = $\frac{2}{5} \times \frac{7}{19} = \frac{14}{95}$

or, B) P(two prime numbers are drawn in a row) = 14/95

A piece of rubber tubing maintains a cylindrical shape as it is stretched. At the instant that the inner radius of the tube is 2

professor190 [17]

Answer:

the rate of change in volume is dV/dt = 4π mm³/s = 12.56 mm³/s

Step-by-step explanation:

since the volume V of a cylinder is related with the height H and the radius R through:

V = πR²*H

then the change in time is given by the derivative with respect to time t

dV/dt = (∂V/∂R)*(dR/dt) + (∂V/∂H)*(dH/dt)

the change in volume with radius at constant height is

(∂V/∂R) = 2*πR*H

the change in volume with height at constant radius is

(∂V/∂H) = πR²

then

dV/dt = 2π*R*H *(dR/dt) + πR²*(dH/dt)

replacing values

dV/dt = 2π* 2 mm * 20 mm * (-0.1 mm/s) + π (2 mm) ²* 3 mm/s = 4π mm³/s

dV/dt = 4π mm³/s = 12.56 mm³/s
