They are both drawn as right angled triangles so if we can constract them then they should obey pythagoras theorem

First traingle:- 8^2 = 64
7^2 + 6^2 = 49 + 36 = 85 so this does not obey the theorem and you cant draw it.

Second traingle: 9^2 = 81 and 5^2 + 7^2 = 25 + 49 = 75 so we cant draw that one either.

For which of these sets of data would all the points be displayed on a scatterplot if the window size on a regression calculator

Ivan

Answer:

Step-by-step explanation:

Oh, this is a lot easier than you made it sound, lol.

This is the correct answer:

The table with the following:

X=6,7,9,11,13,14

Y=27,33,39,49,58,71

Lol, I didn't realize that was all this was.

Anyways, the table that matches that is correct, that's actually a bit obvious. The numbers you gave me are parameters, a limit. The numbers for x per y have to fall between those numbers listed.

A local talent is selling underground CD’s to get his rap career off the ground.

bogdanovich [222]

Answer:

He should sell his CD's for $2.

Step-by-step explanation:

Each crate contains 60 blank CD’s and each crate cost $35.

This means that he will pay $35 for 60 CD's.

How much should he sell his CD’s to make a profit of $85?

He will sell each of the 60 CD's for x, which means that his earnings will be of 60x.

Profit: Earnings - Cost = 60x - 35

To make a profit of $85

$60x - 35 = 85$

$60x = 120$

$x = \frac{120}{60}$

$x = 2$

He should sell his CD's for $2.

You can model the population of a certain city between 1955-2000 by the radical function

OverLord2011 [107]

Complete Question:

You can model the population of a certain city between 1955-2000 by the radical function

P(x) = 55,000 sqrt x-1945

Using this model, in which year was the population of that city 275,000?

Answer:

In 1970 population of that city is 275,000

Solution:

Given that,

You can model the population of a certain city between 1955-2000 by the radical function :

$P(x) = 55000\sqrt{x - 1945}$

To find: year in which was the population of that city 275,000

Therefore,

x = ?

P(x) = 275000

Thus we get,

$275000 = 55000\sqrt{x - 1945}\\\\Divide\ both\ sides\ by\ 55000\\\\\frac{275000}{55000} = \sqrt{x-1945}\\\\5 = \sqrt{x - 1945}\\\\Take\ square\ on\ both\ sides\\\\25 = x - 1945\\\\x = 1945 + 25\\\\x = 1970$

Thus, in 1970 population of that city is 275,000
