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

Answer:
5.75
Step-by-step explanation:
5.00×0.15=.75 5.00+.75=5.75
Given:
Investment (P) = $10000
Rate of interest (R) = 3.5%
Time (T) = 7 years
To find:
Amount in the account after 7 years
Solution:
Simple interest formula:
Simple interest = $2450
Amount = Investment + Interest
= 10000 + 2450
= 12450
Therefore $12,450 will be in the account after 7 years.
