Question

anyone willing to help me out with a few trig application questions? like ferris wheel questions and stuff like tht?

Answer 1

the thing is im doing an online quiz, and need help.

Answer 2

On a typical day at an oceanport, the water has a maximum depth of 24 m at 4:00 am. The minimum depth of 12 m occurs 6.3 hours later. Assume that the relationship between the depth of the water and time is a sinusoidal function. The equation to represent this function can be written in the form y = a cos[b(t - c)] + d.

Answer 3

find the value of a,b,c,d

Answer 4

What is the depth of the water, to the nearest metre, at 11:18 am?

Answer 5

At what time, to the nearest hour, does the water reach a depth of 15 m for the third time on the same day? Record your answer in 24 hour time system. (e.g. for 3:25 pm, put 15, for 8:45 pm, put 21)

Answer 6

those are the three questions

Answer 7

heres the second question: The pedals of a bicycle are mounted on a bracket whose centre is 36 cm above the ground. Each pedal is 19 cm from the centre of the bracket. Assuming that the bicycle is pedalled at 12 cycles per minute and that the pedal starts at time t = 0 s at the topmost position.
The equation to represent this function can be written in the form y = a cos[b(t - c)] + d, where y is the height of the pedal from the ground in cm and t is the time in seconds.

find the value of a,b,c,d.

Answer 8

good Question. :)

Answer 9

yea got an answer?
