Can I get this as soon as possible

8. State a possible sine and cosine equation (two equations total) for the following graph. y = 9+3 - 6. 10 2 Amp. 9- 6 - 3 . 360 X = 70 * = 18 - 5/ fix ) = 3005 ( 18x) +6 fix ) - 3 sin / 8 /X+$ ) +6 of 10 15 20 [3] 9. The Bay of Fundy in New Brunswick has one of the highest vertical tide ranges in the world. The water depth at a certain point can be modeled by the function D(t) = 7 cos (30t) + 9, where D(t) is the water depth in meters and t is the time in hours since midnight. a. What is the period of the function? What does it represent in this situation? Fer = 360 +30= 12. the time between the 2 occurences of tide. [4] b. What is the range of water depths in the Bay of Fundy? - ? to ? C. How deep will the water be at 6 pm? D ( 6 ) = 7 cas ( 20) 16 ) + 9 = 2 d. Give a possible equation for the depth of the water if the amplitude was lower but the peak was the same. DI ) =
