Answer:
Step-by-step explanation:
X^4+x=0
X(X^3+1)=0
X(X+1)(x^2-x+1)=0
X=0, x=-1, x=(1+3^1/2i)x=(1-3^1/2i)
Answer:
No
Step-by-step explanation:
If they are a Pythagorean triple, then the square of the largest number will equal the sum of the squares of the other 2 numbers.
largest number = 9 and 9² = 81
6² + 8² = 36 + 64 = 100 ≠ 81
Thus 6, 8 and 9 are not a Pythagorean triple

is formula for compounded quarterly interest rate.
Where P = 5000, r = 10% = .10, n = 4 (since its compounded quarterly), and t = 20
Now we plug all variables into the equation.
