so far, i think i got that the period is 4 and the minimum is 1. i can't find anything else. please help.

2nd:

*d*, is modelled by the equation

a) How many days is there until the new moon (no moon visible)?

b) Including tonight, how many full moons will there be in the next 100 days?

c) How many days will it be until there are five full moons, including tonight’s?

d) Without using trigonometric ratios, write a simple equation that tells how many days away the next

*x*full moons are. Why can the equation be so simple and consistent?

Verify my work please? let me know if i'm right or wrong.
