Answer:
x^3 - 2x^2 + 9x - 18.
Step-by-step explanation:
The complex roots occur in conjugate pairs so there are 3 roots 2, 3i and -3i.
So we have:
P(x) = (x - 2)(x - 3i)(x + 3i)
= (x - 2)(x^2 - 9i^2)
= (x - 2)(x^2 - 9*-1)
= (x - 2)(x^2 + 9)
= x^3 + 9x - 2x^2 - 18
= x^3 - 2x^2 + 9x - 18.
Answer:
Total length of the road = 6 3/4 miles.
Each markers are spaced at a distance = 1/8 of a mile.
Step-by-step explanation:
Total length of the road ÷ each marker space =
a) 6 3/4 ÷ 1/8.
b) In order to solve it, we need to convert that fraction into improper fraction:
6 3/4 = 27/4
6 3/4 ÷ 1/8 = 27/4 ÷ 1/8
We need to convert division sign into multiplication sign and flip the second fraction.
27/4 × 8/1
then simplify to get
27 × 2 = 54.
There would be total number of 54 markers of lengths (1/8) of a mile.
