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

y from the player. The height $y$y​ (in feet) of a second hockey puck is modeled by $y=x\left(0.15-0.001x\right)$y=x(0.15−0.001x)​ , where x$x$x​ is the horizontal distance (in feet). Compare the distances traveled by the hockey pucks before hitting the ground.

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

6.338 rounded to the nearest thousand
ANTONII [103]

Answer:

6.338

this is the same because thousandths means 3 decimal places and it already has only 3 places, so it is already rounded to the thousandths. Rounded to hundredths place would be 6.34 and tenths would be 6.3.

A body is accelerated continuously. What is the form of the graph?
sleet_krkn [62]

For a body moving with increasing acceleration, the graph will be in the form of an exponential function. An example of the exponential function is shown in the attached diagram.

Mathematically exponential function can be expressed by the following equation.

<span>F(a) = e^a, where a>0.</span>

Find the distance between the points ( - 9, - 12) and (18, - 12)
ANTONII [103]

Hello from MrBillDoesMath!

Answer:

27



Discussion:

By the distance formula (or Pythagorean theorem)

distance =   sqrt ( (change in x)^2 + (change in y)^2)


In our case this becomes

distance =   sqrt (   (18 - (-9) )^2 + (-12 - ( -12))^2)

               =  sqrt (    ( 18 + 9) ^2   + ( -12 + 12) ^ 2)

               =  sqrt (  ( 18 + 9) ^2 + 0^2 )

               = sqrt ( 27^2)

               = 27

 

Geometrically, as both y coordinates = -12, the points define a horizontal line segment. The length is then simply the difference of the x coordinates, 18 - (-9) = 18 +9 = 27. Same answer as before



Thank you,

MrB

Evaluate: 16^1/2 x 2^-3
kykrilka [37]

Answer:

64

Step-by-step explanation:

16^1

---------------------- = 64

2 x 2 - ^3

Apply exponent rule

16^1 = 16

= 16

------------------

2x2 - ^3

16 = 2x 8

2 x 8

-----------

2 x 2 - ^3

Cancel the common factor <2>

8

---------

2-^3

Factor the number 8 = 2^3

2^3

----------

2-^3

Apply exponent rule.

= 2^3 - (-3) = 6

3- (-3) = 6

= 2^6

2^6 = 64

64 is the answer
