EXERCISE 13.3 Q NO. 5

If x, 2x+ 2, 3x + 3 are in G.P. , then the fourth term is (A) 27 (B) -27 (C) 13.5 (D) -13.5

Divide 13.3 inot the ratio 2:5

13/5-5/13 =

5/13-5/13 =

Given that P 12, Q = 5 and R = 13 also P+Q=R, then the angle between P and Q will be

Find the coordinates of the point R on the line segment joining the points P(-1,3) and Q (2,5) such that PR =(3)/(5) PQ.

The reciprocal of the fraction 2 3/5 is (a) 2 5/3 (b) (13)/5 (c) 5/(13) (d) 2 2/5

A(-2, 2, 3) and B(13, -3, 13) and L is a line through A. Q. Equation of a line L, perpendicular to the line AB is

A tangent P Q at a point P of a circle of radius 5 cm meets a line through the centre O at a point Q so that O Q=13 c m . Find the length of P Q .

Use property to evaluate: 13^(3) + (-8)^(3) + (-5)^(3)
