Answer:
4/7= 12/21- mutiply the fraction by 3
(4)(3)/(7/(3)= 12/21
4/7= 16/28 - mutiply by 4
4/7= 20/35- mutiply by 5
Answer:
Step-by-step explanation:
The function that could model this periodic phenomenon will be of the form
The tide varies between 3ft and 9ft, which means its amplitude is
and its midline is
.
Furthermore, since at the tide is at its lowest ( 3 feet ), we know that the trigonometric function we must use is .
The period of the full cycle is 14 hours, which means
giving us
With all of the values of the variables in place, the function modeling the situation now becomes
1. x = 16
2. x = 46
Good luck
Six divided by five maybe and add a 1
Dividing by coefficient other than +1
