AlexFokin [52]

Answer:

Length of the volleyball court in drawing = 2 mm

Step-by-step explanation:

8 meter  = 8 *1000 = 8000 mm

Scale factor = 1 : 8000

Length of the volleyball court in drawing = x

1 : 8000 :: x : 16000

\dfrac{1}{8000}=\dfrac{x}{16000}\\\\\\\dfrac{1}{8000}*16000=x\\\\

x = 2 mm

A tunnel is in the shape of a parabola. The maximum height is 31 m and it is 13 m wide at the base as shown below.
yan [13]
Using the given values from the problem and the illustration, three points are known which are (0,0), (6.5,-31), (-6.5,-31). The first step in solving this problem is to determine the equation of the parabola.
y = ax²
-31 = a(6.5)²
-31 = 42.25a 
a = -31/42.25 
a = -124/169 

Therefore, the equation of the parabola is y = (-124/169)x². The value 4.5 is then substituted in the equation as x to get the answer which is 16.14 meters.
