The amount of water remaining in the pool is decreasing at a rate of

Gnom [1K]

The average rate of change has a relationship with slopes. In this way, we can write the slope of a line as follows:

$Slope=\frac{Change \ y}{Change \ x}$

As you can see in the graph, we have a straight line whose slope is negative. This slope as we have said is the Average Rate of Change we need to find. So, to find the slope of this line we must choose two points and compute the following formula:

$ARC=Slope=\frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1}}$

The two points can be:

$P_{1}(0,40) \ and \ P_{2}(10,0)$

So:

$ARC=\frac{0-40}{10-0} \\ \\ \therefore \boxed{ARC=-4 \ gallons \ per \ minutes}$

Finally, the conclusion is:

The amount of water remaining in the pool is decreasing at a rate of 4 gallons per minute

madam [21]

They relate because the original constant of proportionality is a unite rate. Then the flipped constant of proportionality would not be a unit rate. It's basically the reciprocal of the original constant of proportionality or K.

It takes 24 electricians 36 days to wire a new housing subdivision. How many days would 32 electricians take to do the same job?

Jlenok [28]

Answer:

The 32 electricians are expected to finish the job in 27 days.

Step-by-step explanation:

In this case we can apply a rule of three to calculate the time it'll take for the 32 electricians to finish the job. This is done below:

24 electricians -> 36 days

32 electricians -> x days

We have to be careful here, since the variables are inversely proportional, since if there are more electricians working on the same job, we expect the job to be finished in fewer days, therefore we need to invert one of the fractions as shown below:

$\frac{24}{32} = \frac{x}{36}\\32*x = 36*24\\x = \frac{864}{32}\\x = 27$

The 32 electricians are expected to finish the job in 27 days.
