A hockey player strikes a hockey puck. The height of the puck increases until it reaches a maximum height of 3 feet, 55 feet awa
MariettaO [177]

Answer:

The maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels further  

Also the distance of the maximum height of first pluck from the player is less than the distance of the second pluck from the player hence the second pluck travels further

Step-by-step explanation:

From the question we are told that

  The maximum height of the first pluck is  h_1 =  3 \  ft

   The height of the second height is mathematically represented as

              $y=x\left(0.15-0.001x\right)

=>           y=0.15x -0.001x^2

Generally at maximum height  y' = 0

So

      y'=0.15 -0.002 x = 0

=>    x =  75 \  ft

Here 75 ft is the horizontal distance the second pluck traveled at maximum height

   So the maximum height of the second pluck is mathematically represented as

       y=0.15(75) -0.001(75)^2

=>     y=  5.625 \  ft  

So comparing the maximum height  of the first and the second pluck we see that the maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels father

9). option e is correct side - side - side

10). SSS

11). 1 ( because with the given info. u can calculate the perimeter of the traingle only )

12) through the given info we can only find the perimeter of the traingle

so,

perimeter = sum of all sides

→ 9.2 + 8.5 + 10.8 = 28.5 m
