The domain of f /g consists of numbers x for which g(x) does not equal to 0 that are in the domains of f and g.

According to the statement

we have given that the The domain of f /g consists of numbers x And we have to find the value of the g(x).

So, For this purpose, we know that the

Domain of a function is the set of all possible inputs for the function.

And according to definition it is clear that the , domain is the input value of the function,

And it is impossible that the function have a 0 zero input value in the functions f(x) and the g(x).

Every function have at least 1 domain or input value.

So, The domain of f /g consists of numbers x for which g(x) does not equal to 0 that are in the domains of f and g.

luvenia can row 4mph in still water. She takes as long to row 7 mi upstream as 21 mi downstream. how

xeze [42]

Answer:

The speed of the river is 2mph.

Step-by-step explanation:

I guess that we want to find the speed of the river.

First, remember the relation: speed*time = distance

If the speed of the river is Sr, when Luvenia moves downstream (in the same direction that the flow of the water) the total speed will be equal to the speed of Luvenia in still water plus the speed of the water:

Sd = 4mph + Sr

and at this speed, in a time T, she can move 21 miles, so we have:

Sd*T = (4mph + Sr)*T = 21 mi

When moving upstream, the speed will be:

Su = (4mph - Sr)

and in the same time T as before, she moves 7 miles, so we have the equation:

Su*T = (4mph - Sr)*T = 7 mi

Then we have two equations:

(4mph + Sr)*T = 21 mi

(4mph - Sr)*T = 7 mi

Now we can take the quotient of those two equations and get:

((4mph + Sr)*T)/((4mph - Sr)*T) = 21/7

The time T vanishes, and we can solve it for Sr.

(4mph + Sr)/(4mph - Sr) = 3

4mph + Sr = 3*(4mph - Sr) = 12mph - 3*Sr

4*Sr = 12mph - 4mph = 8mph

Sr = 8mph/4 = 2mph.

Oksana_A [137]

Answer: $H_0:\mu\geq33$

$H_a:\mu$

Step-by-step explanation:

Let $\mu$ be the average number of hours a person drive without adding the product.

Given claim : An infomercial claims that a woman drove 33 hours without oil.

i.e. $\mu\geq33$

It is known that the null hypothesis always contains equal sign and alternative hypothesis is just opposite of the null hypothesis.

Thus the null and alternative hypothesis for the given situation will be :-

$H_0:\mu\geq33$

$H_a:\mu$

Answer:

The ship is traveling at 25 mph

Step-by-step explanation:

12.5/0.5=25

25/1=25

37.5/1.5=25

The speed is constant (25) so the ship is moving at 25 mph

Which of the following is not a way to determine if a relation is a function?

Dima020 [189]

D. Determine if the relations’ graph forms a line.

Step-by-step explanation:

A function is a relation if the input values lead to only one output value.The input values, normally x values make up the domain, where as the output values form the domain.A function is a relation where the input values are associated with a single output.The vertical test is used to determine if a curve is a function.The line graph should only hit a single point on the curve.
