1a) Possible rational roots will be of the form
±{divisor of 10}/{divisor of 4}
Divisors of 10 are {1, 2, 5, 10}
Divisors of 4 are {1, 2, 4}
Then possible rational roots are
{±1/4, ±1/2, ±1, ±5/4, ±2, ±5/2, ±5, ±10}
1b) Your answer is correct.
2) One additional root will be the conjuate of the given complex root.
5 -3i
3) If one root is 5 -√7, another will be 5 +√7. Then your polynomial is
P(x) = (x -(5 -√7))*(x -(5 +√7)) = (x -5)^2 -(√7)^2
P(x) = x^2 -10x +18
Answer: A,C
Step-by-step explanation: They are facing each other making them interior angles
Answer:
divide 88 by the number of x
88/8= 11
X = 11
The number of ways is 40320
<h3>How many ways could a group of 8 seated?</h3>
The group of people is given as:
Group = 8
The number of ways this group can be seated is calculated as:
Ways = Group !
So, we have
Ways = 8!
Expand
Ways = 8 * 7 * 6 * 5 * 4 * 3 *2 *1
Evaluate
Ways = 40320
Hence, the number of ways is 40320
