<span>The correct answer is: Option (D) Human body
Explanation:
Measurements were first based on the parts of human body. For example the old Eygptian "cubit" was the unit of length. It was measured by using the forearm.
1 cubit = The length from the elbow of the forearm to the tip of the middle finger.
In a nutshell, it is the human body that was used as the reference to measure things up.</span>

Answer:
y=1/6x+13/3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-4)/(4-(-2))
m=1/(4+2)
m=1/6
y-y1=m(x-x1)
y-4=1/6(x-(-2))
y-4=1/6(x+2)
y=1/6x+2/6+4
y=1/6x+1/3+4
y=1/6x+1/3+12/3
y=1/6x+13/3
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 :
<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.
