Surface area is the area that is on the outside of a figure and will be used when you have to cover something, but a volume is an area inside an object and is used in finding the amount someone can hold within something else.
Answer:
The answer is below
Step-by-step explanation:
Given the function as:
f(x)=5sin(πx / 15)+180,
a) The angular frequency (ω) = 2π * frequency
but ω = π/15, hence:
π/15 = 2π * frequency
frequency = (π/15)/2π
frequency = 1/30 hertz
Period (T) = 1/frequency = 1/(1/30) = 30 seconds
b) The period is 30 seconds. This means that it reaches the maximum temperature every 30 seconds.
In one hour (3600 s), the number of times the function reaches a maximum temperature = 3600 s / 30 s = 120
Answer:
2 hours
Remember that time = distance/rate
The distance you need to cover is 56 miles, while you go 28 miles per hour. Using these, we get this:
time=56/28
time=2
So it will take two hours to go across a 56 mile wide bay at 28 mph.

Answer:
272 feets
Step-by-step explanation:
Badwater Basin = 279 feets below sea level = - 279 feets (relative to sea level)
New Orleans = 7 feets below sea level = - 7 feets (relative to sea level)
Hence,
New Orleans is higher Than Badwater Basin by :
279 feets - 7 feets
= 272 feets
Answer:
The coordinates of B are (1,-5).
Step-by-step explanation:
To find the coordinates of point 
we will apply section formula.
Its used to find out if any line segment is of any 
ratios.
As the lie segment is joining the points internally we will use section formula for internal points.
Lets say that is having coordinates 
then 
and 
Now we have 
we call it 
then 
we call it 
.
And 
,
Plugging all the values in section formula we have.
Similarly
So the coordinates of
