• ### Population Project

1. 1. Population Project JapanBy: Mikaela Fringer
2. 2. Japan Population
3. 3. Linear Equation Linear Equation: y=mx+bYou need to pick 2points and then use Slope: y1-y2those for the x1-x2equations. Point Slope: y-y1 = m(x-x1)
4. 4. Linear Equation Prediction: 1,207,500
5. 5. Work for Linear Equation
6. 6. Quadratic Equation Quadratic Equation : y=ax^2 + bx + cIn this part we got 3 points toﬁnd a, b, and c. When doingthis you have to useelimination and substitution.Then at the end you have toplug it in to the originalequation to check youranswer.
7. 7. Quadratic Equation Prediction: 1,636,906
8. 8. Work for Quadratic Equation a = 0.000105 b = 0.628858 c = 27
9. 9. Logarithmic Equation For this you use y = ab^x. You do separate equations for the different points. Remember to go back and check your answers.
10. 10. Logarithmic Equation Prediction: 1,630,264
11. 11. Work for Logarithmic Equation
12. 12. Explanation for ProjectThe reason all the predictionsare different because we are Linear Equationusing a different equation to Prediction: 1,270,500predict each time. So int heend the Quadratic and Quadratic EquationLogarithmic were close in the Prediction: 1,636,906same area. Logarithmic Equation Prediction: 1,630,264
