We know that
A difference of two perfect squares (A² - B²) <span>can be factored into </span><span> (A+B) • (A-B)
</span> then
x ^4-4--------> (x²-2)*(x²+2)
(x²-2)--------> (x-√2)*(x+√2)
x1=+√2
x2=-√2
the other term
(x²+2)=0-> x²=-2-------------- x=(+-)√-2
i <span> is called the </span><span>imaginary unit. </span><span>It satisfies </span><span> i</span>²<span> =-1
</span><span>Both </span><span> i </span><span> and </span><span> -i </span><span> are the square roots of </span><span> -1
</span><span>√<span> -2 </span></span> =√<span> -1• 2 </span><span> = </span>√ -1 •√<span> 2 </span> =i • <span> √<span> 2 </span></span>
The equation has no real solutions. It has 2 imaginary, or complex solutions.
x3= 0 + √2<span> <span>i
</span></span>x4= 0 - √2<span> i </span>
the answer is
the values of x are
x1=+√2
x2=-√2
x3= 0 + √2 i
x4= 0 - √2 i
Answer:
a. 25%
b. $1560
c. $130
Step-by-step explanation:
a.
If 75% is paid by company, the rest is paid by Ruth.
Out of 100%, 75% is paid by company, so Ruth pays 100 - 75 = 25%
b.
Per year, the total amount paid is 6240, but Ruth pas 25% of this. So,
25% = 0.25
To get the answer, we multiply 0.25 with 6240.
0.25 * 6240 = 1560
So, $1560 is paid by Ruth annually.
c.
Since 1560 is paid annually (in 12 months), each month Ruth has to pay:
1560/12 = $130
Hence, $130 is deducted each month from her paycheck
The answer to the percentage of home team fans in attendance is 89%
