MATHEMATICS

UNIT: REAL NUMBERS:

1. A class of 20 boys and 15 girls are divided into ‘n’ groups so that each group has ‘x’ boys & ‘y’ girls. Find ‘x’ ,’y’ & ‘n’. What values are referred to?

2. Prove that √ 11is irrational number3. Write the denominator of the rational number257/2250 in the form 2nx5m, where ‘n’ & ‘m’ are

non-negative integers; hence write its decimal expansion without actual division.4. Show that the square of any positive odd integer is of the form 8m+1 for some integer ‘m’.5. Prove that 1/(2+√ 3) is an irrational number.

UNIT: POLYNOMIALS:

1. Find the zeroes of the polynomial l4 √3 x2+5x-2√3and verify the relationship between the zeroes and the coefficients.

2. . If the zeroes of the polynomial x2-5x+kare the reciprocal of each other then find the value of ‘k’

3. Find all zeroes of the polynomial x4-7x2+12if it is given that two of its zeroes are √ 3 and -√ 3.4. If ‘α’ & ‘β’ are the zeroes of the quadratic polynomial 4x2 -4x+1, find the value of (α/β)+(β/α)5. On dividing p(x)=5x4-4x3+3x2-2x+1 by g(x)=x2+2, if q(x)=ax2+bx+c, find a, b, c.

UNIT : Apair of linear equations in two variables:

1. Determine graphically whether the pair of linear equations 2x+3y=7; 6x+9y=21is consistent(dependent), consistent(independent) or inconsistent?

2. Draw the graphs of the following pairs of linear equations: 5x-4y-12=0; x+2y-8=0; also determine the coordinates of the vertices of the triangle formedby the graph lines and the ‘x’ axis.

3. Find the values of ‘a’ & ‘b’for which the following system of linear equationshas infinitely many solutions: 3x-(a+1)y=2b-1; 5x+(1-2a)y=3b.

4. Determine the values of ‘k’so that the following linear equations have no solution ;(3k+1x)+3y-2=0; (k2+1)x+(k-2)y-5=0

5. Solve the following equations: a) 47x+31y=63 b) 152x-378y=-74 31x+47y=15 -378x+152y=-604

ACTIVITIES:Real numbers:Pictorial representation of H.C.F of two numbersPolynomials:Take any quadratic polynomial and find its zeroes graphically.A pair of linear equations in two variables:Take a linear equation in two variables of your choice;Write another linear equation in two variables such that the geometrical representation of the pair so formed is a) Intersecting lines b) parallel lines c)coincident lines
