M(x) = 5x + 4     n(x) = 6x - 9

Part 1 (m + n)(x) = 5x + 4 + 6x - 9
                           = 11x - 5

Part 2 (m * n)(x) = (5x + 4)(6x - 9) = 30x^2 - 21x - 36

Part 3 m[n(x)] = 5(6x - 9) + 4
                       = 30x - 45 + 4
            = 30x - 41

A cylinderical container of height 28cm and diameter 18cm is filled with water. The water is then poured into another container
tiny-mole [99]

Answer:

h = 24 cm

Step-by-step explanation:

volume of water in the cylinder = volume of water in the rectangular base container

But ,

volume of cylinder = \pir^{2}h

where:  is the radius and h is the height.

volume of cuboid = length x width x height

                             = l x w x h

So that;

\pir^{2}h = l x w x h

But, r = \frac{diameter}{2} = \frac{18}{2} = 9 cm, height of cylinder = 28 cm, length = 27 cm, width = 11 cm, \pi = \frac{22}{7}.

Thus,

\frac{22}{7} x (9)^{2} x 28 = 27 x 11 x h

\frac{22}{7} x 81 x 28 = 27 x 11 x h

7128 = 297h

h = \frac{7128}{297}

  = 24

h = 24 cm

The depth of the water in the container is 24 cm.
