Prove that the parallelogram circumscribing a circle is rhombus.
Ans Given : ABCD is a parallelogram circumscribing a circle.
To prove : - ABCD is a rhombus or
AB=BC=CD=DA
Proof: Since the length of tangents from external are equal in length
∴AS = AR .....(1)
BQ = BR .....(2)
QC = PC .....(3) SD = DP .....(4)
Adding (1), (2), (3) & (4).
AS + SD + BQ + QC = AR + BR + PC + DP AD + BC = AB + DC
AD + AD = AB + AB
Since BC = AD & DC = AB (opposite sides of a parallelogram are equal)
2AD = 2AB
∴AD = AB .....(5)
BC = AD (opposite sides of a parallelogram)
DC = AB .....(6) From (5) and (6)
AB = BC = CD = DA Hence proved

The center of a national park is located at (0,0). A special nature preserve is bounded by by straight lines connecting the points A at (3,2), B at (5,1), C at (8,4) and D at (6,5)
A garden shop wishes to prepare a supply of special fertilizer at a minimal cost by mixing two fertilizers, A and B. The mixture is to contain at least 45 units of phosphate at lea
NATURAL NUMBERS The numbers 1, 2, 3, 4.... Are called as natural numbers, their set is shown by N. Hence N = {1, 2, 3, 4, 5....} WHOLE NUMBERS The numbers 0, 1, 2, 3, 4
Determine equation of the tangent line to f (x) = 4x - 8 √x at x = 16 . Solution : We already know that the equation of a tangent line is specified by,
x=±4, if -2 = y =0 x=±2, if -2 = y = 0
