MODELING REAL LIFE A baseball is thrown up in the air. The table shows the heights $y$ (in feet) of the baseball after $x$ secon
nikklg [1K]

The equation for the path of the ball can be measured using a regression model calculator which produced the quadratic model ;

  • y(x) = - 16x² + 36x + 4
  • Height at x = 1.7 = 18.89 feets

<u>The table given</u> :

Time, x : __0.5 ___ 1 ____ 1.5 ____ 2

Height, y _ 18 ____22 ___ 24 ____ 12

<u>Using </u><u>technology</u><u> such as a </u><u>quadratic regression</u><u> calculator or </u><u>excel</u> ;

The quadratic regression model obtained is :

  • y(x) = - 16x² + 36x + 4

<u>The </u><u>height after, 1.7 seconds</u><u>, x = 1.7 can be calculated thus</u> :

Put x = 1.7 in the equation :

  • y(1.7) = - 16(1.7)² + 36(1.7) + 4
  • y = 18.89 feets

Therefore, the height of the baseball after 1.7 seconds will be 18.89 feets.

Evaluate: 11 + sqrt(-4 + 6×4÷3)
Murrr4er [49]

Answer:

11+\frac{2\sqrt{15}}{3}

Step-by-step explanation:

11 + \sqrt{(-4 + 6\times4\div3)} \\\\11+\sqrt{\frac{-4+6\times \:4}{3}}\\\\\sqrt{\frac{-4+6\times \:4}{3}}=\frac{2\sqrt{5}}{\sqrt{3}}\\\\=11+\frac{2\sqrt{5}}{\sqrt{3}}\\\\\frac{2\sqrt{5}}{\sqrt{3}}=\frac{2\sqrt{15}}{3}\\\\=11+\frac{2\sqrt{15}}{3}
