What will be the maximum height h (t)=-16t^2+128t+320

Mathematics

Korvikt [17]4 years ago

To determine the maximum height, h, from the given above. Differentiate the function and equate to zero. Then, determine the value of t. The value, when substituted to the original function, will give the maximum height. For this given, 
                                           dh(t)/dt = -32t + 128 = 0, t = 4

Substituting t = 4 to the original function gives 320. Thus, the maximum height is 320 units.

I believe it's 4. 1/2 = 1/4 
so, 1/2 + 1/2 + 1/2 + 1/2 would be 4/4...

Answer:

x=

Step-by-step explanation:

1.first solve the hypotenuse of (12 squared+16 squared) = (Hy squared)

2.then find the square root of the Hypotenuse

{h}^{2}  +  {b}^{2}  =  {hy}^{2}

This cuboid is made from cm squares
11Alexandr11 [23.1K]

Answer:

Step-by-step explanation:

Each signal unit cubes are 1 cm to each side

the dimensions of the large cube is 4 by 6 by 3      width height and depth

a) volume of the cube   Vol = area of the base times height  

              area of the base = the width times the depth  

              Volume = Base Depth

                            =  Width x Depth x Height

                            =      4 x 3 x 6

                            =       12 x 6

                Vol      =   72 cm ³

b )  the volume of the smaller cuboid has different dimensions    

             the smaller cube is 2 by 2 by 1      width height and depth

          Volume = Base Depth

                            =  Width x Depth x Heigh

                            =    2 x 2 x 1  

 Vol smaller cuboid    =   4

      How many smaller cubes can be made?

            The obvious answer might be to straight up divide the large cube volume by the smaler cuboid volume. That might work IF all of the cuboid dimensions divide evenly into the cube dimensions.

  Number of cuboid  =   Volume of the cube  /  Volume of the cuboid

                                  =             72 / 4

                                  =        18

Check this answer by dividing the dimension of the cube by the cuboid

         4 by 6 by 3

         2 by 2 by 1

      (4/2) by (6/2) by (3/1)

        2    by    3   by     3       = 2 x 3 x 3     =    18
