|
Answer» A polynomial function is the sum of terms, each of which consists of a transformed power function with positive whole number power. The degree of a polynomial function is the highest power of the variable that occurs in a polynomial. The term containing the highest power of the variable is called the leading term. Thus, power or degree of polynomial 3x^2 + 4x + 1 is 2 |

Example11: A wall of length 10 m was to be built across an open ground. The heightof the wall is 4 m and thickness of the wall is 24 cm. If this wall is to be built up withbricks whose dimensions are 24 cm × 12 cm × 8 cm, how many bricks would berequired? |
|
Answer» Solution:- length of the wall, l = 10 m = 100 cm Breadth of the wall, b = 42 m = 4200 cm Height of the wall, h = 5 m = 500 cm Volume of the wall = l × b × h = 100 cm × 4200 cm × 500 cm = 21000000 cm3 Dimension of the brick = 42 cm × 12 cm × 10cm ∴ Volume of each brick = 42 cm × 12cm × 10 cm = 5040 cm3 Let the number of bricks required be n. n × Volume of each brick = Volume of the walltherefore, n= vol of the wall/ vol of each brick n= 21000000cm³/5040cm³ n= 4166.67 Thus, the number of brick required is 4166.67 |
