What is the coefficient of the x9y-term in the binomial expansion of (2y 4x3)4?

Sonbull [250]

The binomial expansion: $T_{k+1}= \frac{n!}{(n-k+1 )!}a^{n-k} b^{k}$
a = 2y, b = 4 x^3, n = 4
( x )^3k = x^ 9
k = 3
$T_{4}= \frac{24}{6}(2y) ^{3-1} (4x^{3} )^{3}$
$T4=512 x^{9} y$
Answer: the coefficient is 512.

Write the equation of the sphere in standard form. x^2 + y^2 + z^2 + 2x − 4y − 6z = 22

madam [21]

The equation $x^{2} +y^{2} +z^{2} +2x-4y-6z=22$ in standard form looks like $(x+1)^{2} +(y-2)^{2} +(z-3)^{2} =(6)^{2}$ .

Given equation of sphere be $x^{2} +y^{2} +z^{2} +2x-4y-6z=22$ .

We are required to express the given equation in the standard form of the equation of sphere.

Equation is basically relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation,quadratic equation, cubic equation or many more depending on the powers of variables. The standard form of the equation of sphere looks like $x^{2} +y^{2} +z^{2} =r^{2}$ .
