Find the value of Q, where `Q=(8B)/sqrt(H)int_0^H(H-h)sqrt(h)(dh)`

Tangents are drawn to x^2+y^2=16 from P(0,h). These tangents meet x-axis at A and B.If the area of PAB is minimum, then value of h is: (a) 12sqrt2 (b) 8sqrt2 (c) 4sqrt2 (d) sqrt2

lim_(x rarr0)(sqrt(x-h)-sqrt(x))/(h)

ABC is an isosceles triangle inscribed in a circle of radius rdot If A B=A C and h is the altitude from A to B C , then triangle A B C has perimeter P=2(sqrt(2h r-h^2)+sqrt(2h r)) and area A= ____________ and = __________ and also ("lim")_(xvec0)A/(P^3)=______

If A is the area an equilateral triangle of height h , then (a) A=sqrt(3)\ h^2 (b) sqrt(3)A=h (c) sqrt(3)A=h^2 (d) 3A=h^2

"lim_(h rarr0)(sqrt(x+h)-sqrt(x))/(h)

Evaluate lim_(hto0)(sqrt(x+h)-sqrt(x))/(h)
