Match each description when z = 9 + 3i. 1. Real part of z, 3 2. Imaginary part of z, 9 - 3i 3. Complex conjugate of z, 3i 4. 3i
- z -3i 5. Z - 9, -9 6. 9 - z, 9
1 answer:
Answer:
see below
Step-by-step explanation:
z = 9 + 3i
This is in the form a+bi where a is the real part and b is the imaginary part
1.The real part is 9
2. The imaginary part is 3
The complex conjugate is a-bi
3. complex conjugate 9-3i
4. 3i - z = 3i - (9+3i) = 3i -9 - 3i = -9
5. z-9 = 9+3i - 9 = 3i
6. 9-z = 9- (9+3i) = 9-9-3i = -3i

Answer:
x=-0.688
Step-by-step explanation:
-2496-3744x+36 = -759x-414-10x
-2460-3744x = -769x-414
-2975x = 2046
17 + 2 = 19 km is 1/2 of the total length, that is,
19 = (1/2)h
(1/2)h = 19 multiply both sides by 2
h = 2*19
h = 38 km
The total length in kilometers is 38 km
