What is the percentage difference between 26 and 14?

topjm [15]

Answer:

0.12%

Step-by-step explanation:

Percent means out of hundred

therefore 26 in percentage is written as

$\frac{26}{100} = 0.26$

=0.26%

and 14 in percentage is written as

$\frac{14}{100}$

=0.14%

percentage difference between 26 and 14 , therefore

=0.26% - 0.14%

=0.12%

Factorise x^2-y^2-2x+6y-8

Talja [164]

X^2 - y^2 - 2x + 6y - 8
= (x^2 - 2x + 1) - (y^2 - 6y + 9) - 8 - 1 + 9 
= (x - 1)^2 - (y - 3)^2 
= [(x - 1) - (y - 3) ] [(x - 1) + (y - 3)] 
= (x - 1 - y + 3) ( x - 1 + y - 3) 
= (x - y + 2) (x + y - 4)

HELP BECAUSE IM STUPID!

mixer [17]

I don't think you're stupid. ^^
Let's take the third term, 8. If n=3, then an should be 8.
The first answer gives 15+2.5*3=22.5.
The second answer gives 15.5+2.5=23.
The third answer gives 15-2.5*3=7.5.
The fourth answer gives 15.5-2.5*3=8.
Choice 4 is correct.

Let's try to actually find the equation on our own.
The equation for an arithmetic series is an=a0+dn where a0 is the term that comes before the first term.
The first term given is 13 and it decreases by 2.5 each time so n=-2.5 and the term that would be before 13 is 15.5.
Thus the equation is an=15.5-2.5n
