Answer:
3-i
Step-by-step explanation:
1-5i + 2 +4i
We add the real parts
1+2 =3
We add the imaginary parts
-5i + 4i = -1i
The complex number is
3-i
C. f(x)= log 1/x^2 , c=/ 0
Answer:
$260
Step-by-step explanation:
GIven
P=$250
R=4%
T=1 year
The total amount of simple interest is
A=P(1+rt)
substitute
A=250(1+0.04*1)
A=250(1.04)
A=250*1.04
A=$260
Hence the total amount is $260
Answer:
8a - 2ab + 2b - 15
Step-by-step explanation:
(12a - 9ab + 5b - 3) - (4a - 7ab + 3b + 12)
(12a - 9ab + 5b - 3) - 4a + 7ab - 3b - 12
12a - 4a - 9ab + 7ab + 5b - 3b - 3 - 12
8a - 2ab + 2b - 15
