Answer:

2x^3 - 2x^2 - 3x -6 -(4/x^4 - 4x^3 + x^2 +2)

Step-by-step explanation:

x-2 = 0

since there is a missing x you have to put in a 0

2 | 1 -4 1 0 2

1 2 -4 -6 -6

1 -2 -3 -6 -4

x^3 x^2 x # remainder

bring down the 1 then multiply by 2 then add to -4

take the -2 multiply by 2 and add to 1 continuously do the samething

now take all the x's and go down one since you're taking out a x

put ing standard form

2x^3 - 2x^2 - 3x -6 -(4/x^4 - 4x^3 + x^2 +2)

i beleive that's the answer, good luck on whatever you're doing

D^2(y)/(dx^2)-16*k*y=9.6e^(4x) + 30e^x

MA_775_DIABLO [31]

The solution depends on the value of $k$ . To make things simple, assume $k>0$ . The homogeneous part of the equation is

$\dfrac{\mathrm d^2y}{\mathrm dx^2}-16ky=0$

and has characteristic equation

$r^2-16k=0\implies r=\pm4\sqrt k$

which admits the characteristic solution $y_c=C_1e^{-4\sqrt kx}+C_2e^{4\sqrt kx}$ .

For the solution to the nonhomogeneous equation, a reasonable guess for the particular solution might be $y_p=ae^{4x}+be^x$ . Then

$\dfrac{\mathrm d^2y_p}{\mathrm dx^2}=16ae^{4x}+be^x$

So you have

$16ae^{4x}+be^x-16k(ae^{4x}+be^x)=9.6e^{4x}+30e^x$
$(16a-16ka)e^{4x}+(b-16kb)e^x=9.6e^{4x}+30e^x$

This means

$16a(1-k)=9.6\implies a=\dfrac3{5(1-k)}$
$b(1-16k)=30\implies b=\dfrac{30}{1-16k}$

and so the general solution would be

$y=C_1e^{-4\sqrt kx}+C_2e^{4\sqrt kx}+\dfrac3{5(1-k)}e^{4x}+\dfrac{30}{1-16k}e^x$

What is the median distance jumped 7.48, 7.60, 7.15, 7.44, 7.73, 7.72

irga5000 [103]

It would be 7.54 because you fist have to put the numbers ordered smallest to biggest amount 7.15, 7.44, 7.48,7.60, 7.72, 7.73 so the numbers that are in the middle are 7.48 and 7.60 you add them up, and the result you divide by 2 which gives you 7.54.

Please someone help me I’m confused

insens350 [35]

Answer:

a2 =14

a4 = 22

a11 = 50

Step-by-step explanation:

an = 10 + (n-1) *4

n is the term number

Let n =2

a2 = 10 +(2-1)*4 =10 +(1)*4 = 14

Let n =4

a4= 10 + (4-1)*4 = 10 *3*4 = 10+12 = 22

Let n = 11

a11 = 10 +(11-1)*4 = 10 *10*4 = 10+40 = 50

Craig examines the effect of different genres of music, such as jazz, rock, rap, on task performance. Which type of measurement

ryzh [129]

Answer:

Nominal

Step-by-step explanation:

Data can be divided into 2 types:

Qualitative Data
Quantitative Data

Qualitative data represent some attribute or characteristic and cannot be measured or calculated. This type of data uses Nominal or Ordinal level of measurement.

Quantitative data is the data which can be measure or calculated. This type of data is expressed in Ratio or Interval scale.

Different genres of music represent an attribute, hence the data is Qualitative. Qualitative data which can put into some order is at Ordinal scale of measurement, while if the data simply represent the name or attributes it would be at Nominal Level.

Different genres of music cannot be put into some order and are just names, hence the measurement scale would be Nominal.
