how that every member of the family of functions y = (4 ln(x) + C)/x is a solution of the differential equation x2y' + xy = 4. (

Sergeeva-Olga [200]

$y=\dfrac{4\ln x+C}x\implies y'=\dfrac{x(4\ln x+C)'-(4\ln x+C)(x)'}{x^2}=\dfrac{4-4\ln x-C}{x^2}$

Substitute this into the differential equation:

$x^2y'+xy=4-4\ln x-C+4\ln x+C=4$

so every solution of the given form $y$ is a solution.

2/3x+14-3x>-7

Ray Of Light [21]

Answer:

$\large\boxed{x$

Step-by-step explanation:

$\dfrac{2}{3}x+14-3x>-7\qquad\text{subtract 14 from both sides}\\\\\dfrac{2}{3}x+14-14-3x>-7-14\\\\\dfrac{2}{3}x-3x>-21\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\dfrac{2}{3\!\!\!\!\diagup_1}x-(3)(3x)>(3)(-21)\\\\2x-9x>-63\\\\-7x>-63\qquad\text{change the signs}\\\\7x$

In a quadrilateral, a student can draw two diagonals. In a pentagon, a student can draw five diagonals. In a hexagon, a student

ohaa [14]

Hello,

Let's assume a polygonal of n vertices.

Starting from of vertice we can reach n-1 vertices by 2 must be excluded.

So there are n*(n-1-2) possibilities but each possibility is counted twice

Number of diagonals = n(n-3)/2

Examples:
n=4==>#=4*(4-3)/2=4*1/2=2
n=5==>#=5(5-3)/2=5*2/2=5
n=6==>#=6*(6-3)/2=6*3/2=9

n=17==>#=17*(17-3)/2=119.
