Answer:

The graph of atmospheric pressure based on height, in miles, above sea level is attached below.

Step-by-step explanation:

The general exponential function is

f(x)=ab^x

Where a is initial value of the function and b is growth rate.

It is given that the atmospheric pressure at sea level is 14.7 lb/in2. This pressure is reduced by half for each 3.6 miles above sea level.

It means the initial value of the function is 14.7 and the growth factor is (\frac{1}{2})^{\frac{1}{3.6}}.

The required function is

f(x)=14.7(\frac{1}{2})^{\frac{x}{3.6}}

Here, x is distance in miles above the sea-level  and f(x) is atmospheric pressure in lb/in² at x miles above the sea-level.

The table of values is

 x              f(x)

 0             14.7

3.6            7.35

7.2           3.675

10.8         1.8375

Therefore, the graph of atmospheric pressure based on height, in miles, above sea level is attached below.

It could be a linear graph with a negative slope 
x axis  is height above ground and y axis id air pressure
so there willbe a point  at (0,14.7) on y axis representing the pressure at sea level. There will be another point at (3.6, 7.35) where  air pressure is half that at ground level. The straight line will continue until it reaches the x axis  ad (0, 7.2)  where there is no air pressure.

The linear ratio = a : 30a = 1 : 30

volume ratio = 1³ : 30³ = 1 : 900

ratio of larger to smaller = 900 : 1

First taking into account the if he buys in order.

Brian has 10 choices for the first selection of fish, 9 for the second selection and 8 for the third selection.

Thus you have 10*9*8 = 720 possible ways

However the question did not specify if it is in order. Now counting how many possible orders for each selection you can have

fish 1 , fish 2 , fish 3 or
fish 1 , fish 3 , fish 2 or 
fish 2 , fish 1 , fish 3 or
fish 2 , fish 3 , fish 1 or
fish 3 , fish 1 , fish 2 or
fish 3 , fish 2 , fish 1 or

We have 6 order.

dividing the possible ways by the order we have 720 / 60 = 120

The answer is B. 120
