Answer:

  see the attachment

Step-by-step explanation:

The function can be ...

  D(t) = A +Bcos(C(t-p))

where A is the average depth (55+12)/2 = 33.5 cm,

  B is the peak deviation from average, 55 -33.5 = 21.5 cm,

  C is the horizontal scale factor (2π/T) = (2π/3) for a period (T) of 3 seconds,

and p is the phase offset, given as 1.1 seconds.

The function is ...

  D(t) = 33.5 +21.5cos(2π/3·(t -1.1))

MAXImum [283]

answer:

bianca will say fifty nine

bianca will say fifty nine because if you count by threes on your fingers (ex: you hold up three fingers that represent the three students, and go "one two three, four five six,") you will land on the second finger when you say "fifty nine", which means bianca says fifty nine.

i hope this makes sense :-)

How to add and subtract unlike fractions
Andrew [12]
You have to find the least common multiple of the denominators (bottom), and when you do that, you multiply the numerator(top) by the same number. You then add or subtract the numerators. You leave the denominators as they are. Simplify if needed.
