Given:
a + bi = 13 + 9i
Equate the real parts:
a = 13
Equate the imaginary parts:
b = 9
Answer:
a =13
b = 9
(7x-10) - (-6x-8)
distribute the negative to the (-6x-8)
(7x-10) + 6x+8
disregard the parenthesis because addition is associative
7x-10 + 6x+8
combine like terms
13x-2
13x-2 is the answer
2^2a^2+b^2
4a^2+b^2
not sure if this is correct but here ya go
Answer:
1/4 or 0.25
Step-by-step explanation:
Lets plug x and y into the equation. We now have 3/12, which would be equal to 1/4 or 0.25
Answer:
A. 30
Step-by-step explanation:
sin theta = opposite side / hypotenuse
sin B = 8/16
sin B = 1/2
Take the arcsin of each side
arcsin sin(B) = arcsin (1/2)
B = arcsin (1/2)
B = 30
