Answer:
Step-by-step explanation:
Well, first lets get our terms straight.
There's no such thing as "cubic area".
-- The distance along a road is "length". That's how much string you need
to stretch from one end of the road to the other.
-- The amount of surface on a sheet of paper, a floor, or a front yard is "area".
That's how much paint or carpet you need to cover it.
-- And the space inside a balloon, a milk jug, or a room is the "volume".
That's how much water it takes to fill it up.
To find the volume of a room, measure its length, width and height,
and then multiply them all together.
Volume = (length) · (width) · (height) of the room.
If you measure the dimensions of the room in feet, then
the volume will be in cubic feet.
If you measure the dimensions of the room in inches, then
the volume will be in cubic inches.
If you measure the dimensions of the room in meters, then
the volume will be in cubic meters.
You could do the whole building the same way ... multiply its
(length) x (width) x (height) ... but there could be a big problem
trying to do that. You can only do it that way when the space is
the shape of a rectangular prism. That's the shape of an ice cube,
a Rubik's cube, a brick, a cigar box, a pizza box, a suitcase, a
shoe box ... things like that. If the building isn't the shape of a giant
brick or a shoebox, then it probably looks like a stack of several blocks
with different sizes. It might even have some curves on it, so you
can't just pick a length, a width, and a height and multiply them.
In that case, if you need to find the volume of the whole building,
you have two choices:
Choice #1). Get a drawing of the building, and see if it's possible to
break it up into smaller sections, with each section shaped like a brick
or a shoebox. For each section, multiply the (length x width x height)
of that section, and when you've done that for all the sections, add them
all up.
Choice #2). Measure the length, width and height of every room
in the building, use those to calculate the volume of each room,
and when you have them all, add them all up to get the volume of
the whole building.

Answer:
Step-by-step explanation:
Solution:-
- We are to model a sinusoidal function for the number of hours of daylight measured in one year in Ellenville.
- We will express a general form of a sinusoidal function [ f ( t ) ] as follows:
Where,
A: The amplitude of the hours of daylight
w: The angular frequency of occurring event
c: The mean hours of daylight
t: The time taken from reference ( days )
- We are given that the longest day [ 
] occurred on June 21st and the shortest day [ 
] on December 21st.
- The mean hours of daylight ( c ) is the average of the maximum and minimum hours of daylight as follows:
- The amplitude ( A ) of the sinusoidal function is given by the difference of either maximum or minimum value of the function from the mean value ( c ):
- The frequency of occurrence ( w ) is defined by the periodicity of the function. In other words how frequently does two maximum hours of daylight occur or how frequently does two minimum hours of daylight occur.
- The time period ( T ) is the time taken between two successive maximum duration of daylight hours. We were given the longest day occurred on June 21st and the shortest day occurred on December 21st. The number of days between the longest and shortest day will correspond to half of the time period ( 0.5*T ):
![0.5*T = 7 + 31 + 31 + 30 +31 +30 +21\\\\T = 2* [ 181 ] \\\\T = 362 days](https://tex.z-dn.net/?f=0.5%2AT%20%3D%207%20%2B%2031%20%2B%2031%20%2B%2030%20%2B31%20%2B30%20%2B21%5C%5C%5C%5CT%20%3D%202%2A%20%5B%20181%20%5D%20%5C%5C%5C%5CT%20%3D%20362%20days)
- The angular frequency ( w ) is then defined as:
- We will now express the model for the duration of daylight each day as function of each day:
