If A be the area of a right triangle and b one of the sides containing the right angle, prove that the length of the altitude on the hypotenuse is 2 Ab /√ b4+4A2.
Ans: Let QR = b
A = Ar(ΔPQR)
A = 1/2 x b x PQ
PQ = 2A/b ...........................(1)
Δ PNQ ∼ ΔPQR (AA)
⇒ PQ/PR = NQ/QR .....................(2)
From Δ PQR
PQ2 + QR2 = PR2
4A2/ b2 + b2 = PR2
Equation (2) becomes
2 A/bxPR = NQ/b
NQ = 2A/PR
NQ = 2 A/√4 A2 + b4
f(x)=x^2-5x+6, determine inverse of f(x)!
Q. What are Mutually Exclusive events? Mutually Exclusive Events are mutually exclusive if they cannot occur at the same time. For example, if you roll one die, you canno
Determine dy & Δy if y = cos ( x 2 + 1) - x as x changes from x = 2 to x = 2.03 . Solution Firstly let's deetrmine actual the change in y, Δy . Δy = cos (( 2.03) 2
Explain How to Distribute simplifying expressions? The distributive law states that for all numbers a, b, and c, a(b + c)= ab + ac What does this mean in plain language?
