The solution is n= <u>+</u> 4i/√11
Step-by-step explanation:
step 1: 10n^2+n^2+16=0
step 2: 11n^2+16=0
step 3: 11n^2= -16
step 4: n^2= -16/11
step 5: taking square root on both sides,
n= √(-16)/√11 (square root of a negative number is a <u>complex term</u> 'i')
n= <u>+</u> 4i/√11
He entered the black hole and stayed there for a while :p
The upper quartile for NFC is 3 points higher than that of AFC.
<h3>What is the difference in the upper quartiles?</h3>
A box plot is used to study the distribution and level of a set of scores. The scores are distributed into 4 groups. Each group has a value of 25%
On the box, the third line on the box represents the upper quartile. 75% of the scores represents the upper quartile.
Upper quartile for AFC : 26
Upper quartile for NFC : 23
Difference = 26 - 23 = 3

Answer:
Step-by-step explanation:
<u>Solving in steps</u>
- x^2(x - 1)(x - 4) - 2x^3 = -6x^2, x > 0
- x^2(x^2 - 5x + 4) -2x^3 + 6x^2 = 0
- x^4 - 5x^3 + 4x^2 - 2x^3 + 6x^2 = 0
- x^4 - 7 x^3 + 10x^2 = 0
- x^2 - 7x + 10 = 0
- x^2 - 2x - 5x + 10 = 0
- x(x - 2) - 5(x - 2) = 0
- (x - 2)( x - 5) = 0
- x - 2 = 0 ⇒ x = 2
- x - 5 = 0 ⇒ x = 5
