The value of x from the given parameters is x = -1/7

<h3>How to determine the value of x?</h3>

The given parameters are:

Point E is between points D and F

DF = 18x - 1

DE = 3x + 5

EF = -x - 8

The statement point E is between points D and F, ​means that

DF = DE + EF

Substitute the known values in the above equation

So, we have:

18x - 1 = 3x + 5 + x - 8

Collect the like terms

So, we have

18x - 3x - x = 5 - 8 + 1

Evaluate the like terms

14x = -2

Divide both sides by 14

x = -1/7

Hence, the value of x from the given parameters is x = -1/7

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.
