If `P=(1,1),Q=(3,2)` and `R` is a point on x-axis then the value of `PR+RQ` will be minimum at

Let P be (5, 3) and a point R on y=x and Q on the x-axis be such that P Q+Q R+R P is minimum. Then the coordinates of Q are

A man starts from the point P(−3,4) and reaches at point Q(0,1) touches x-axis at point R such that PR+RQ is least then position of point R is (a) (3/5,0) (b) (-3/5,0) (c) (-2/5,0) (d) (-2,0)

If ^n P_r=^n P_(r+1)a n d^n C_r=^n C_(r-1,) then the value of n+r is.

Let P be a point on the curve c_(1):y=sqrt(2-x^(2)) and Q be a point on the curve c_(2):xy=9, both P and Q be in the first quadrant. If d denotes the minimum distance between P and Q, then d^(2) is ………..

What is meant by Respiration Quotient (R.Q.)?When will be the value of R.Q be 1 and when will be it less than 1?

The parabola y=x^2+p x+q cuts the straight line y=2x-3 at a point with abscissa 1. Then the value of pa n dq for which the distance between the vertex of the parabola and the x-axis is the minimum is (a) p=-1,q=-1 (b) p=-2,q=0 (c) p=0,q=-2 (d) p=3/2,q=-1/2

If a^(-1), b^(-1), c^(-1) are p^(th),q^(th) and r^(th) terms of an AP then the value of |(bc,ca,ab),(p,q,r),(1,1,1)| is

Plot the points P(1,0),Q(4,0), and S(1,3). Find the coordinates of the point R such that PQRS is a square.

A point P lies on x-axis and another point Q lies on y-axis. :- If the abscissa of point P is - 12 and the ordinate of point Q is-16, calculate the, length of line segment PQ.
