There is a difference between a research topic and a research question. A research question provides a foundation for creating a

True [87]

The research question is important to a researcher as it helps in solving the issue that the researcher wants to solve.

The research topic will be "Social media has an effect on the behavior of children".

The research question will be "what effect does social media has on the effects of the behavior of children".

The null hypothesis will be "there is no statistical significance between social media and children's behavior".

The alternative hypothesis will be "there is a statistical significance between social media and children's behavior".

The null hypothesis will be rejected when the p-value is equal to the significance level or it's less than it.

Write the partial fraction decomposition fro the ration expression below

zlopas [31]

$\dfrac{5x-2}{(x-1)^2}=\dfrac a{x-1}+\dfrac b{(x-1)^2}$
$5x-2=a(x-1)+b$

Since $5x-2=5x-5+3=5(x-1)+3$ , it follows that $a=5$ and $b=3$ , so

$\dfrac{5x-2}{(x-1)^2}=\dfrac5{x-1}+\dfrac3{(x-1)^2}$

$\dfrac{x^3+x^2+x+2}{x^4+x^2}=\dfrac{x^3+x+x+2}{x^2(x^2+1)}=\dfrac ax+\dfrac b{x^2}+\dfrac{cx+d}{x^2+1}$
$x^3+x^2+x+2=ax(x^2+1)+b(x^2+1)+(cx+d)x^2$
$x^3+x^2+x+2=(a+c)x^3+(b+d)x^2+ax+b$

When $x=0$ , you find that $b=2$ . It's also clear that $a=1$ . So the remaining constants must be $1+c=1\implies c=0$ and $2+d=1\implies d=-1$ , and so you get

$\dfrac{x^3+x^2+x+2}{x^4+x^2}=\dfrac1x+\dfrac2{x^2}-\dfrac1{x^2+1}$

A = ½ (a + b) h

A = ½ (3 + 10) 4

A = (3+5)4

A = (8)4

A = 32
