13.

1. 6x2-13x+5=0

Answer»

6x² - 13x + 5 = 0

6x² - 3x - 10x + 5 = 0

3x ( 2x - 1) - 5 ( 2x - 1) = 0

(3x - 5) ( 2x - 1 ) = 0

So, x = 5/3 and 1/2

an experimental set up tor determination of resistance of a given resistor,it is adsetathe plug from the key when the ooservations are not being taken. Why'

Answer»

It is usually advised to switch of the circuit while not taking the reading during the verification of ohm's law because when the current is passed through the resistor , then due to the heating effect , the temperature of the setup rises and hence , ohm's law cannot be verified properly as ohm's law states a condition of constant temperature.

Write power of 3x +4x +1.

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

if 36 flats cost Rs 68251500 what is the cost of each such flat

Answer»

cost of 36 flats = Rs. 68251500i.e cost of 1 flat 68251500÷36 = 1895875

the cost of each flat is ₹1895875

68251500/36=1895875each flat= 1895875

cost of 36. flat = Rs 682515001 flat cost is 68251500 ÷ 36= 1895875
