Answer:

Step-by-step explanation:

y''-4y=cosx

The auxialary equation and solutions are as follows:

m^2-4=0\\m=2,-2

General solution is

y=Ae^{2x} +Be^{-2x}

Right side =cosx

Particular Integral

= \frac{cosx}{-1-4} =\frac{-cosx}{5}

Hence full solution is

The value of x from the given expression is; x= -2/3

<h3>Solving one-variable equations</h3>

The given expression is;

  • 23(9x+6) = 6x + 4.

Hence, when we expand the equation; we have;

  • 207x + 138 = 6x +4

  • 207x - 6x = 4 - 138

  • 201x = -134

  • x = -134/201

  • x = -2/3

Look at the data set below:
Elenna [48]
Median: Sort from least to greatest and find the # in the middle.
Sort: 54, 58, 58, 60, 62. 
Number in the middle: 58, so the median is 58.
Mode: 58, because it appears most. 
Range: Subtracting bigger number from smaller number.
Finding it: 62-54 = 8
If you want to find the mean, then here:
Mean: Solving average (adding all #s together and dividing by how many numbers are there) <span>58 + 54 + 62 + 58 + 60 = 292.
</span>Divide by 5 = 58.4
Hope that helps you. Good luck with it.

ioda
40%less You take 36/60 That equals 60% This means that 36 is 60% of 60 So in 24 is 40% of 60 or 36 is 40% less than 60
