A power outage occurs 6 min after the ride started passengers must wait for their cage to be manually cranked into the lowest position in order to exit the ride. Sine function model: 82.5 sin 3 pi (t+0.5)+97.5 where h is the height of the last passenger above ground measured in feet t is the time of operation of the ride. The complete ride takes 15 minutes.
(A)- What is the height of the last passenger at the moment of the power outage?
(B)- will the last passenger to board the ride need to wait to exit the ride?

h = 15 ft

He would not have to wait - Already at the bottom!

Step-by-step explanation:

Given:-

- The position of the last passenger from ground on the ferris wheel is given by a sine function as follows:

                           h = 82.5*sin(3*pi*(t + 0.5)) + 97.5

- The ride takes 15 minutes to complete.

- The power outage occurs at 6 mins.

Find:-

(A)- What is the height of the last passenger at the moment of the power outage?

(B)- will the last passenger to board the ride need to wait to exit the ride?

Solution:-

- The height of the last passenger at t = 6 mins from start point can be evaluated from the given modelling function h.

                           h = 82.5*sin(3*pi*(6 + 0.5)) + 97.5

                           h = 82.5*(-1) + 97.5

                           h = 15 ft

- How far away is the last passenger at t = 6 mins from bottom position for him to exit the ride.

                           Min [h] =  [ 82.5*sin(3*pi*(t + 0.5)) + 97.5 ]

                           Min [sin ( at + b ) ]  = -1

                           Min [h] = 82.5(-1) + 97.5

                                       = 15 ft

- After 6 mins the last passenger is already at the bottom most position. He would not have to wait!  

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
