Answer:

3/400

Step-by-step explanation:

Let w represent earth's water

let f represent fresh water and let g represent ground water

f = \frac{1}{40}w

g =\frac{3}{10}f = \frac{3}{10}(\frac{1}{40}w)\\ \\g = \frac{3}{400}w

Therefore, fraction of earth's water,w, that is ground water = 3/400

Answer: Ground water is 3/400 of earth's water

Step-by-step explanation:

Let x represent earth's water,

F represent earth's fresh water, and

G represent earth's ground water.

The statement can then be expressed as follows:

About 1/40 of the earth's water is fresh water:

(1/40)x = F

About 3/10 of the earths fresh water is ground water:

Say: (3/10)F = G

=> (3/10)(1/40)x = G

(3/400)x = G

Therefore, ground water is 3/400 of the earth's water.

The graph of f(x) =sqrt of x is reflected across the x-axis and then across the y-axis to create the graph of function g(x). Whi
pickupchik [31]

The original function is

f(x)=√x

As this is condition for √x function, x≥ 0

So,

Domain= [0, infinity)

Range= [0, infinity)


After the reflection across x-axis and y-axis, we get a function,

g(x)=-√-x

-x≥ 0 means x≤ 0,

So,

Domain= (-infinity, 0]

Range= (-infinity, 0]


From this you can see that

-The only value that is in the domains of both functions is 0.

-The range of g(x) is all values less than or equal to 0.


only these points are correct and all other points are wrong.


See the attached graphs for both functions.
