The chesapeake bay tides vary between 4 feet and 6 feet. the tide is at its lowest point when time (t) is 0 and completes a full cycle in 12 hours. what is the amplitude, period, and midline of a function that would model this periodic phenomenon?
amplitude = 1 foot; period = 12 hours; midline: y = 5
amplitude = 2 feet; period = 6 hours; midline: y = 1
amplitude = 2 feet; period = 12 hours; midline: y = 5

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

22 dimes and 9 nickels

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

care to share were the trapezoid shown is ?
