It will be 80 because 80/4=20 and 20+80=100
Answer:
It would be 20
Step-by-step explanation:
As we can see, the sequence starts from 5 and increases by three each time. In fact, one possible formula for that sequence could be:
Let's confirm the formula by evaluating the first 6 terms:
45.5 acres of land can be farmed and 24.5 cannot be farmed.
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
