Answer:
The equation of the parabola that models the path of the long jumper through the air is ×
Step-by-step explanation:
Mathematically, we know that parabolas are second-order polynomials and every second-order polynomials, also known as quadratic functions, can be constructed by knowing three different points of the curve. The standard form of the parabola is:
×
×
Where:
x - Horizontal distance from the start line, measured in meters.
y - Height of the long jumper, measured in meters.
a,b,c - Polynomial constants, measured in , dimensionless and meters, respectively.
If we know thatand
this system of linear equations is presented below:
The coefficients of the polynomial are, respectively:
The equation of the parabola that models the path of the long jumper through the air is
But we need y measured in centimeters, then, we use the following conversion:
Then, we get that:
Where x and y are measured in meters and centimeters, respectively.
The equation of the parabola that models the path of the long jumper through the air is
