If x, y, z are integers and x greater or equal than 0, y greater or equal than 1, z greater or equal than 2, x + y + z = 15, then the number of values of the ordered triplet (x, y, z) is -

Let y = p + 1 and z = q + 2.
Then x greater or equal than 0, p greater or equal than 0, q greater or equal than 0 and x + y + z = 15
rightwards double arrow x + p + q = 12
therefore The reqd. number of values of (x, y, z) and hence of (x, p, q)
= No. of non-negative integral solutions of x + p + q= 12
= Coeff. of x12 in (x0 + x1 + x2 + ……)3
= Coeff. of x12 in (1 – x)–3
= Coeff. of x12 in [2C0 + 3C1 x + 4C2 x2 + ….]
= 14C12 = fraction numerator 14 factorial over denominator 2 factorial 12 factorial end fraction = fraction numerator 14 cross times 13 over denominator 2 end fraction = 91.

The cartesian equation of r squared c o s space 2 theta equals a squared is

A quadratic equation, or sometimes just quadratics, is a polynomial equation with a maximum degree of two. It takes the following form:
ax² + bx + c = 0
where a, b, and c are constant terms and x is the unknown variable.
Now we have given the equation as r squared c o s space 2 theta equals a squared.
Now we know that:
cos space 2 theta equals cos squared theta minus sin squared theta.
So applying this, we get:
r squared left parenthesis cos squared theta minus sin squared theta right parenthesis equals a squared
Now lets substitute x=rcosθ and y=rsinθ, we get:
r squared cos squared theta minus r squared sin squared theta equals a squared
x squared minus y squared equals a squared

A small source of sound moves on a circle as shown in the figure and an observer is standing on O. Let n subscript 1 end subscript comma n subscript 2 end subscript and n subscript 3 end subscript be the frequencies heard when the source is at A comma blank B blankand C respectively. Then

At point A comma source is moving away from observer so apparent frequency n subscript 1 end subscript less than n (actual frequency) At point B source is coming towards observer so apparent frequency n subscript 2 end subscript greater than n and point C source is moving perpendicular to observer so n subscript 3 end subscript equals n
Hence n subscript 2 end subscript greater than n subscript 3 end subscript greater than n subscript 1 end subscript
