A Ferris wheel has a radius of 10 m, and the bottom of the wheel passes 1 m above the ground. If the Ferris wheel makes one comp
Volgvan

Answer:1+10(1-\cos (\frac{\pi t}{9}))

Step-by-step explanation:

Given

radius of wheel r=10 m

Time period of Wheel T=18 s

and T\cdot \omega =2\pi , where \omega =angular velocity of wheel

\omega =\frac{2\pi }{18}

Let at any angle \thetawith vertical position of a point is given by

x=r\sin \theta

y=y_0+r(1-\cos \theta )

and \theta =\omega \times t

for velocity differentiate x and y to get

v_x=r\cos \theta =r\cos (\omega t)

v_y=0+r(\sin \theta )=r\sin (\omeag t)

Height at any time t is given by

h=1+10(1-\cos \theta )=1+10(1-\cos (\frac{\pi t}{9}))

IrinaVladis [17]

Answer:

Option A - The number of visitors is multiplied by (1+r) each year

Step-by-step explanation:

Given : The number of visitors to an art museum increases each year. The function V(t) = N(1 + r)^t represents the number of visitors to the museum at year t, where N is the number of visitors in year 0 and r is the rate of increase.  

To find : Select the correct statement?

Solution :

We have given an exponential function,

The function V(t) = N(1 + r)^t represents the number of visitors to the museum at year t, where N is the number of visitors in year 0 and r is the rate of increase.  

As In year 0,

The initial visitors is V(t) = N(1 + r)^0=N

In year 1,

V(t) = N(1 + r)^1=N(1+r)

In year 2,

V(t) = N(1 + r)^2

So, According to this the number of visors is multiplied by (1+r) each year.

Therefore, Option A is correct.
