I think it's B cuz
2.3 * 10^-4 = 16.1
And
1.7 * 10^-4 = 10.2
So 16.1 - 10.2 = 5.9
Rounded= 6
I'm not sure tho

It took my question down twice here's a real math question I guess
aliina [53]

Answer:

n-3

Interval notation: (-\infty, -10)\cup(-3,\infty)

Step-by-step explanation:

<u>First inequality:</u>

<u />n+8

Therefore, this inequality restricts:

n \in \mathrm{R};\: n

<u>Second inequality:</u>

< 8+n-3

Therefore, this inequality restricts:

n \in \mathrm{R};\: n>-3

Therefore, with both of these restrictions together, we have:

\fbox{$n \in \mathrm{R}; n-3$}\\\mathrm{or\:}\fbox{$n-3$}\\\mathrm{or\:}\fbox{$(-\infty, -10)\cup(-3,\infty)$}.

The formula for any geometric sequence is a n = a 1 · r n - 1 , where a n represents the value of the nth term, a 1 represents t
AfilCa [17]

Answer:

Step-by-step explanation:instead, try making the subscripts and superscripts stand out:

                         n-1

a    =  a         * r

 n         n-1

Believe me, it's worth the extra work to do this!!

Given the sequence   -3, -6, -12, -24, you can easily see that the first term,

a         is    -3.  The common factor is 2.  Note how (-3)*2=-6, and so on.

  1

So, a       = -3 and r=2.

        1

So the formula for this geometric sequence is  

                  n-1

a     =  -3*2

  n

Use the method of undetermined coefficients to solve the following differential equation: y′′+4y=4x
nikklg [1K]

Answer:

y(x) = C_1 cos 2 x + C_2 sin 2 x + x

Step-by-step explanation:

given,

y′′ + 4 y = 4 x

D² y + 4 y = 4 x

(D²+4) y = 4 x

now, writing Auxiliary  equation

m² + 4 = 0

m² = -4

m = ± 2 i

now, complimentary function

y_c = e^{ax}(C_1 cos b x + C_2 sin b x)

a = 0 ,  b = 2

y_c =C_1 cos 2 x + C_2 sin 2 x

particular integral (y_p)

y_p = a x

y'_p = a

y"_p = 0

now,

y′′+ 4 y = 4 x

0+ 4 (a x )= 4 x

4 a x = 4 x

     a = 1

now,

  y_p = x

now, general equation

y(x) = y_c + y_p

y(x) = C_1 cos 2 x + C_2 sin 2 x + x
