Answer:
sqrt(14)
Explanation:
The absolute value of a complex number a+bi can be calculated as follows:
|a+bi| = sqrt(a^2 + b^2)
we have:
a = -4
b = -sqrt(2) i
Substitute with the values in the above equation to get the absolute value as follows:
|a+bi| = sqrt [(-4)^2 + (sqrt(2) i)^2] = sqrt(14)
Answer:
In 2 days Susan's lunch account balance will be less than Evelyn's
Step-by-step explanation:
Susan has a balance of $ 110 which will be enough for = 110/6= 18 days
