Answer:
Step-by-step explanation:
we have to divide the given distance by 3.
Then we will be able to find the distance between markers.
Given distance is
Since, there are three markers,
So, we have to divide this distance by 3
So, the distance between markers is-
So, the distance between marker is
Now, we have to convert this into mixed number.
Then, the distance is-
Answer:
A) -2 - i√3 , -2 + i√3
Step-by-step explanation:
Solve using quadratic formula
x² + 4x + 7 = 0
The Almighty Formula
= -b ± √b² - 4ac/2a
Where ax + bx² + c = 0
From the above question
a = 1, b = 4, c= 7
Hence,
-4 ± √4² - 4 × 1 × 7/2 × 1
-4 ± √16 - 28/2
=( -4 ± √-12)/2
Since
b² - 4ac < 0
We have two complex roots
Simplifying
( -4 ± √-12)/2
= -4/2 ± √-12/2
= -2 ± 2√3i/2
= -2 ± √3i
Therefore,
-2 - √3i , -2 + √3i
or
-2 - i√3 , -2 + i√3
Option A , is the correct answer
Use a calculator. 6 square root of 2 and 8 square root of 2. Times both of them and turns to 2304. Then 2304 square root of 2 again
