Answer:

Step-by-step explanation:

you have to

first multiply the numbers you have in the column with the ones in the rows

8x* 5x = 40x² top left

8x* (-3) = -24x bottom left

-1 * 5x = -5x top right

-1* (-3) = 3 bottom right

second add and subtract all

40x²-24x-5x+3 = 40x²-29x+3

Triangle ABC is rotated 45° about point X, resulting in triangle EFD. If EF = 4.2 cm, DF = 3.6 cm, and DE = 4.5 cm, what is CB?
Margaret [11]
This is the concept of transformations, given that ABC was rotated it implies that it retained it's original dimensions. This means that ABC is proportional to EFD. Therefore, given that EF=4.2 cm, DF=3.6 cm and DE=4.5 cm. The CB=FD=3.6 cm

Differential Equations - Reduction of order
iren [92.7K]
With reduction of order, we assume a solution of the form y_2=zy_1=ze^{2x}, with z=z(x). Then

{y_2}'=(z'+2z)e^{2x}
{y_2}''=(z''+4z'+4z)e^{2x}

and substituting into the ODE gives

x(z''+4z'+4z)e^{2x}-(2x+1)(z'+2z)e^{2x}+2ze^{2x}=0
x(z''+4z'+4z)-(2x+1)(z'+2z)+2z=0
xz''+(2x-1)z'=0

Let \xi(x)=z'(x), so that \xi'=z''. This gives the linear ODE

x\xi'+(2x-1)\xi=0

This equation is also separable, so you can write

\dfrac{\xi'}{\xi}=\dfrac{1-2x}x

Integrating both sides with respect to x gives

\ln|\xi|=-2x+\ln x+C_1
\xi=C_1xe^{-2x}

Next, solve z'=\xi for z by integrating both sides again with respect to x.

z'=\xi
\implies z=\displaystyle\int C_1xe^{-2x}\,\mathrm dx
\implies z=C_1e^{-2x}(2x+1)+C_2

And finally, solve for y_2.

y_2=zy_1=C_1(2x+1)+C_2e^{2x}

and note that y_1 is already taken into account as part of y_2, so this is the general solution to the ODE.

The chart gives three different international calling plans. Jamie has budgeted $20 per month for international calls. Round ans
oksano4ka [1.4K]
A. 200.625 minutes   B. 184.166 minutes  C. 200 minutes  (round these answers like the question asked) 4. Plan A is the best because you get the most minutes for your money. I will explain my work for A, but if you need to explain the rest just ask. So, if you have to pay $3.95 every month no matter what and $0.08 for every minute you talk you can write the equation as, Cost = 3.95 + 0.08m (m stands for minutes), and the cost is 20$ then the equation is 20 = 3.95 + 0.08m, subtract 3.95 from the right side to make it 16.05 = 0.08m, then divide everything by 0.08 to get m, which gives you m= 200.625
