Answer:
$1,774
Step-by-step explanation:
The decrease is 2 weeks out of 52, or 1/26 of the annual pay:
decrease = (1/26)($46,124) = $1,774
The PR specialist should expect his annual pay to decrease by $1774.
Answer is 13 yards of ribbon
Step by step
She started out with $25
She had a remainder of $22.14
Subtract
25 - 22.14 = $2.86 she spent on ribbon
Divide $2.86 by .22 per yard = 13 yards
Problem solved
Answer:
the answer is 2 + i.
Step-by-step explanation:
Let the square root of 3 + 4i be x + iy.
So (x + iy) (x +iy) = 3 +4i
=> x^2 + xyi + xyi + i^2*y^2 = 3 + 4i
=> x^2 – y^2 + 2xyi = 3 + 4i
Equate the real and complex terms
=> x^2 - y^2 = 3 and 2xy = 4
2xy = 4
=> xy = 2
=> x = 2/y
Substitute in
=> x^2 - y^2 = 3
=> 4/y^2 - y^2 = 3
=> 4 – y^4 = 3y^2
=> y^4 + 3y^2 – 4 = 0
=> y^4 + 4y^2 – y^2 – 4 =0
=> y^2(y^2 + 4) – 1(y^2 + 4) =0
=> (y^2 – 1) (y^2 + 4) =0
Therefore y^2 = 1, we ignore y^2 = -4 as it gives complex values of y.
Therefore y = 1 and x = 2/1 = 2
The required square root of 3 + 4i is 2 + i.
