Answers

Answer 1

Complete question is;

Mr. Stein receives a water bill from city hall. He notices that the city charges $50 for fire and sewer service and $3 for every 1000 gallons of water used. Mr. Stein wants to construct a model describing the relationship between the cost of his water bill and the amount of water he uses.

Which statement best describes the model that Mr. Stein should create?

A. Mr. Stein should use a linear model, since the water bill changes at a constant rate relative to the amount

of water he uses.

B. Mr. Stein should use an exponential model, since the water bill changes at a constant rate relative to the amount of water he uses.

C. Mr. Stein should use a linear model, since the water bill changes at a constant percent rate relative to the amount of water he uses.

D. Mr. Stein should use an exponential model, since the water bill changes at a constant percent rate relative to the amount of water he uses.

Answer:

Option A: Mr. Stein should use a linear model, since the water bill changes at a constant rate relative to the amount

of water he uses.

Step-by-step explanation:

We are told that the city charges $50 for fire and sewer service and $3 for every 1000 gallons of water used.

Since there's a fixed charge of $50 for fire and sewer service and also that the city charges $3 for every 1000 gallons of water used. It means that there is a constant rate of charge for every 1000 gallons used.

It means that the bill he gets depends on the rate of water he consumes.

Thus, stein should use a linear model because the water bill changes at a constant rate relative to the water he consumes.

If three times a number is increased by twenty-two, the result is fourteen less than seven times the number. Find the number.​

Answers

Answer:

x = 3.6

Step-by-step:

3 times a number is increased by twenty two = 3x+22

Result ( = ) fourten less than seven times the number =  7x - 14

Since they are equal to each other, you have:

3x + 22 = 7x - 14

Solve:

22 = 10x - 14

36 = 10x

x = 3.6

The statement which is true about the graphed function is that F(x) > 0 over the interval (-∞, -4).

What is Function?

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given is a graph of a function.

The options contains the open interval (-∞, -3) and (-∞, -4).

It is clear that along this interval, the graph is situated above the X axis.

This means that the values of y is all greater than 0.

At x = -4, F(x) = 0

For all x < -4, F(x) > 0

So the correct statement is F(x) > 0 over the interval (-∞, -4).

Hence F(x) > 0 over the interval (-∞, -4).

Stephanie uses a ride service to get to different places in her city. If Stephanie uses Uber the service charges 1.50 per mile . If Stephanie uses lift the service charges $2.00 per mile. Let m represent the number of miles traveled. Which of the following statements are true . Select all that apply

Answers

Answer:

By a small online search, i found that the actual question seems to be:

"Stephanie uses a ride service to get to different places in her city. If Stephanie uses Uber the service charges $5.00 plus 1.50 per mile . If Stephanie uses lift the service charges $2.00 per mile. Let m represent the number of miles traveled. Which of the following statements are true . Select all that apply"

The statements are not provided, so i will answer it in a general way.

We have two different equations:

1) a fixed amount of $5.00 plus $1.50 for each mile, m.

This is a linear equation:

y1 = $1.50*m + $5.00

2) No fixed amount, only $2.00 for each mile, m.

y2 = $2.00*m

Now, the things we can see are which service will be cheaper as a function of m.

To see this, we can see the difference between y1 and y2.

When the difference is negative, this means that y1 is cheaper.

When the difference is positive this means that y2 is cheaper.

When the difference is zero, both services charge the same.

D = y1 - y2 = $1.50*m + $5.00 - $2.00*m

                 = (-$0.50)*m + $5.00

First let's find when it is zero.

              0 =  (-$0.50)*m + $5.00

            5.00/0.5 = m = 10

So for 10 miles, both services charge the same.

As the coefficient that multipies m is negative, if we have m > 10, then the difference will be negative.

This means that for m > 10, y1 is cheaper.

Then for m < 10, y2 is cheaper.

John Jay Friends and Fellow-citizens: The Convention concurred in opinion with the people, that a national government, competent to every national object, was indispensably necessary; and it was as plain to them, as it now is to all America, that the present Confederation does not provide for such a government. These points being agreed, they proceeded to consider how and in what manner such a government could be formed, as, on the one hand, should be sufficiently energetic to raise us from our prostrate and distressed situation, and, on the other, be perfectly consistent with the liberties of the people of every state. Like men to whom the experience of other ages and countries had taught wisdom, they not only determined that it should be erected by, and depend on, the people, but, remembering the many instances in which governments vested solely in one man, or one body of men, had degenerated into tyrannies, they judged it most prudent that the three great branches of power should be committed to different hands, and therefore that the executive should be separated from the legislative, and the judicial from both. Thus far the propriety of their work is easily seen and understood, and therefore is thus far almost universally approved; for no one man or thing under the sun ever yet pleased everybody. Suppose this plan to be rejected; what measures would you propose for obtaining a better? Some will answer, Let us appoint another convention; and, as every thing has been said and written that can well be said and written on the subject, they will be better informed than the former one was, and consequently be better able to make and agree upon a more eligible one. . . . Let those who are sanguine in their expectations of a better plan from a new convention, also reflect on the delays and risks to which it would expose us. Let them consider whether we ought, by continuing much longer in our present humiliating condition, to give other nations further time to perfect their restrictive systems of commerce, reconcile their own people to them, and to fence, and guard, and strengthen them by all those regulations and contrivances in which a jealous policy is ever fruitful. Let them consider whether we ought to give further opportunities to discord to alienate the hearts of our citizens from one another, and thereby encourage new Cromwells to bold exploits. Are we certain that our foreign creditors will continue patient, and ready to proportion their forbearance to our delays?
