Answer:

2916π in^2

Step-by-step explanation:

Step one:

given data

initial table diamter= 96in

we are told that the extension is 6 in over the edge

the new diameter is = 96+6+6= 108in

the radius is = 108/2=54in

we added 6 twice because it will be on the two sides of the diameter

Step two:

the expression for the area is

Area= πr^2

Area=  π*54^2

Area= 2916π in^2

If you have learned how to find the line of best fit manually, then you can do it that way. Perhaps you may want to just find a line that can connect at least two of the points and I believe that that line will be able to represent the other points because, in general, the points are pretty close to one another. 

If you don't want to do it manually and have a graphing calculator (which I recommend) then you can use that to find the line of best fit (and if you want then you can see how precise your points are with your r^2 value). Or there is a website (http://illuminations.nctm.org/Activity.aspx?id=4186), which you can use to help you to find the equation of that particular line. 

Once you have that done, then you can substitute 2009 for the x value in the equation and then see what y value the equation produces. That will then be your answer :)

Answer:

  • See below

Step-by-step explanation:

<u>The roots are:</u>

  • 3, 3, 2 - 3i, 2 + 3i (conjugate of 2 - 3i should be added) and the leading coefficient is - 5

<u>The polynomial is:</u>

  • -5(x - 3)² (x - [2 - 3i]) (x - [2 + 3i]) =
  • - 5(x² - 6x + 9) (x² - 4x + 13) =
  • -5(x⁴ - 10x³ + 46x² - 114x + 117) =
  • -5x⁴ + 50x³ - 230x² + 570x - 585

All together, 3 people have 120 coins. mark has 3 times as many as joel, and joel has 1/2 as many as sandra. how many coins does
oksano4ka [1.4K]
Joel = j, Mark = m, Sandra = s
j + m + s = 120
m = 3j
j = 1/2 s --> s = 2j
plug in (substitute) each letter to make it in terms of only j: j + m + s = 120
j + 3j + 2j = 120
6j = 120
6j/6 = 120/6
j = 20
now plug in for the j & s equation:
s = 2j = 2(20) = 40
Therefore Sandra has 40 coins!
