The population of Collin County, which follows the exponential growth model, increased from 491,675 in 2000 to 782,341 in 2010.
Luden [163]

Answer:

p=ak^t

p1=491272*k^0

p2=782341*k^10

782341/491272 = k^10

k=1.047629

growth rate is 4.7629%

2012: predicted population is 491272*1.047629^12=858,642 people

1245863=491272*1.047629^t

1.047629^k=2.5363599

ln both sides is k ln 1.0476=ln 2.5363

t=20.000 years.

Rule of 72 would say 72/4.76 or 15.12 years for doubling

14.90 years

2017 predicted is 491272*1.0476^17 or 1083552, or more than actual, so the rate of growth is slowing down.

<u>Trigonometry</u>

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

<u>Step 1: Identify</u>

Angle θ = 35°

Opposite Leg BC = <em>x</em>

Adjacent Leg AC = 2

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [Tangent]:                    tan35° = x/2
  2. Isolate <em>x</em>:                                        2tan35° = x
  3. Rewrite:                                          x = 2tan35°
  4. Evaluate:                                        x = 1.40042
  5. Round:                                            x ≈ 1.40
