HELP PLEASE NEED THE ANSWERS FOR MY GEOMETRY FINAL

Mathematics
1 answer:
rodikova [14]3 years ago
6 0

Step-by-step explanation:

slope of the given line=2/3

since the required line is parallel to the given line, it's slope will be same.

hence slope of required line:2/3

The required line passes through the point(9,1),

hence the equation of the required line,

y-1=(2/3)(x-9)

3y-3=2x-18

2x-3y-15=0

There the equation of the required line is 2x-3y-15=0

18 divided by (1+5)(4-2)
crimeas [40]

Answer:

= 3/2

=  \frac{18}{(1 + 5)(4 - 2)}

=  \frac{18}{(6)(2)}

=  \frac{18}{12}

Simplify the fraction.

=  \frac{3}{2}

What is 20.00 multiplied by 20.00
Gala2k [10]

Answer:

400.00

Step-by-step explanation:

20*20 is close to 2*2. Since we have zeros, we can multiply 2 and 2 to get 4. Then we add two zeros because of the zero in 20 and the zero in the other 20. This could also be written as 20^{2} because we're multiplying 20 by itself.

Find a particular solution to the nonhomogeneous differential equation y'' + 4 y = cos(2x) + sin(2x).
alukav5142 [94]
The characteristic solution follows from solving the characteristic equation,

r^2+4=0\implies r=\pm2i

so that

y_c=C_1\cos2x+C_2\sin2x

A guess for the particular solution may be a\cos2x+b\sin2x, but this is already contained within the characteristic solution. We require a set of linearly independent solutions, so we can look to

y_p=ax\cos2x+bx\sin2x

which has second derivative

{y_p}''=(-4ax+4b)\cos2x+(-4bx-4a)\sin2x

Substituting into the ODE, you have

y''+4y=\cos2x+\sin2x
\implies4b\cos2x-4a\sin2x=\cos2x+\sin2x
\implies\begin{cases}4b=1\\-4a=1\end{cases}\implies a=-\dfrac14,b=\dfrac14

Therefore the particular solution is

y_p=-\dfrac14x\cos2x+\dfrac14x\sin2x

Note that you could have made a more precise guess of

y_p=(a_1x+a_0)\cos2x+(b_1x+b_0)\sin2x

but, of course, any solution of the form a_0\cos2x+b_0\sin2x is already accounted for within y_c.
