Question

Can you please help???!!!
It takes a total of 6 hours to fill up an in ground backyard pool using a standard hose. A function can represent this situation to represent the amount of water in the pool until it is full as a function of the time the hose is running. Determine the domain for this function.

The domain is all integers from 0 to 6 hours.

The domain is all even integers from 0 to 6 hours.

The domain is all real numbers from 0 to 6 hours.

The domain is all positive real numbers.

Answer 2

please help???

Answer 3

At time t = 0 the pool is empty. At time t = 6 hours the pool is full.
Once you have a function that represents the amount of water in the pool, you should be able to put any value for t in the domain 0 <= t <= 6 to find the amount of water in the pool. t can be any real number such as: 1, 1.5, 2.8, 3.6589, etc.
So all real numbers from 0 to 6 hours.

Answer 4

thank you @ ranga can you help me with another one?

Answer 5

I will try.

Answer 6

thank you

Answer 7

its- A science experiment begins with a metal at -100° Celsius. The following function describes the temperature change per minute: f(x) = 89x - 100°. How will the graph of this function change if the metal is at 25° at the start of the experiment?

The line will shift vertically up by 125°.

The line will shift vertically up by 25°.

The line will shift vertically down by 125°.

The line will shift vertically down by 25°.

Answer 8

In the first line is the metal at minus 100 or is it just a dash.

Answer 9

its a negative 100

Answer 10

Then it looks like the function f(x) = 89x + (metal temperature at start of experiment)

So if the temp at start is -100, f(x) = 89x - 100

If the temp at start is 25, f(x) = 89x + 25

So that is a shift of +125 in the positive y direction. So choice A)

Answer 11

ok im sorry but can you help with one more it'll be the last one

Answer 12

this is the question-
Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k.

k = ______
