The table shows a proportional relationship between the number of stars Roberto collects in a game and his total points. A row o
maks197457 [2]

Answer:

1) 20 stars; 30 points.

2) 28 stars, 42 points.

3) 38 stars, 57 points.

Step-by-step explanation:

<h3> The missing table is attached.</h3>

Let  be "x" the numbers of stars Roberto collects and "y" his total points.

The proportional relationship has this form:

y=kx

Where "k" is the constant of proportionality.

We can choose the point (8,12) from the table, where:

x=8\\y=12

Substituting these values into  y=kx and solving for "k", we get:

 12=k(8)\\\\\frac{12}{8}=k\\\\k=1.5

Knowing the value of "k", we determine that the  following Numbers of stars and the Total points could be used as the missing values in the table:

1) For x=20 :

y=(1.5)(20)=30

2) For x=28 :

y=(1.5)(28)=42

3) For x=38 :

y=(1.5)(38)=57

Help ! Compare these two functions. Which has the greater rate of change?
ololo11 [35]

Answer:

We know this is a tough job. What we want is so intimate that no one can write it for you.

You must write it yourself, in the language most natural to you. We ask you to write in

your own words and then record in your own voice. You may even find that it takes a

request like this for you to reveal some of your own beliefs to yourself. If you set them

down they may become of untold meaning to others.

We would like you to tell not only what you believe, but how you reached your beliefs,

and if they have grown, what made them grow. This necessarily must be highly personal.

That is what we anticipate and want.

It may help you in formulating your credo if we tell you also what we do not want. We do

not want a sermon, religious or lay; we do not want editorializing or sectarianism or

'finger-pointing.' We do not even want your views on the American way of life, or

democracy or free enterprise. These are important but for another occasion. We want to

know what you live by. And we want it in terms of 'I,' not the editorial 'We.'

Although this program is designed to express beliefs, it is not a religious program and is

not concerned with any religious form whatever. Most of our guests express belief in a

Supreme Being, and set forth the importance to them of that belief. However, that is your

decision, since it is your belief which we solicit.

But we do ask you to confine yourself to affirmatives: This means refraining from saying

what you do not believe. Your beliefs may well have grown in clarity to you by a process

of elimination and rejection, but for our part, we must avoid negative statements lest we

become a medium for the criticism of beliefs, which is the very opposite of our purpose.

We are sure the statement we ask from you can have wide and lasting influence. Never

has the need for personal philosophies of this kind been so urgent. Your belief, simply

and sincerely spoken, is sure to stimulate and help those who hear it. We are confident it

will enrich them. May we have your contribution?
