How many line of symmetry does a hexagon has?

yaroslaw [1]

Since it is a hexagon and it has 6 sides (and we assume it is regular since it doesn't tell us otherwise) then the hexagon will have 6 lines of symmetry (:

Find the general solution of the nonhomogeneous differential equation x^2y''-2y=3(x^2) -1, (x>0).

Ira Lisetskai [31]

Answer:

G.S= $C_1\frac{1}{x}+C_2x^2+x^2logx+\frac{1}{2}$

Step-by-step explanation:

We are given that non-homogeneous differential equation

$x^2y''-2y=3(x^2)-1$

It is Cauchy Euler equation

Substitute x=e^t x>0

Auxillary equation

$D'(D'-1)-2=0$

$D'^2-D'-2=0$

$(D'-2)(D'+1)=0$

$D'-2=0 \implies D'=2$

$D'+1=0\implies D'=-1$

Complementary solution

$y=C_1e^{-t}+C_2e^{2t}$

$y=C_1\frac{1}{x}+C_2x^2$

Particular solution

$y_p=\frac{3e^{2t}}{D'^2-D'-2}-\frac{e^{0t}}{D'^2-D'-2}$

$y_p=te^{2t}+\frac{1}{2}=x^2logx+\frac{1}{2}$

G.S= $C_1\frac{1}{x}+C_2x^2+x^2logx+\frac{1}{2}$

Hence, general solution G.S= $C_1\frac{1}{x}+C_2x^2+x^2logx+\frac{1}{2}$

You are painting the outside of a jewelry box, including the bottom. To find the surface area (S.A.) of the jewelry box, you can

Sergio [31]

1) The radius would be r = x + 4y

.... and the area would be A = pi ( x + 4y )^2 

2) x is not defined. You have to state the relationship of x with l ,w, and, h 

3) The square prism is a cube. I assume that the edge is x. Then the perimeter of any one face is : 

... p = 4x

The Appalachian Trail is 2,174 miles long. If a group of 7 people hike the entire trail, how many combined miles do they hike?

KengaRu [80]

ITS 2,174*7=15,218 SINCE EACH PERSON IS HIKING THE SAME DISTANCE. THAT MEANS EACH PERSON IS HIKING 2,174 MILES
