Answer:
Z = a - 2i - 3ib
Step-by-step explanation:
The complex conjugate has the expression with the opposite sign for the imaginary part.
Complex conjugate of Z=a + 2i + 3ib is,
Z = a - 2i - 3ib
Answer:
1782 cm³
Step-by-step explanation:
First, you measure the volume of the cuboid as a whole which is length x breadth x height, 9 x 12 x 18 = 1944 cm³. Then measure the volume occupied by the space, 3 x 3 x 18 since the hole runs along the entire length = 162 cm³.
Then you subtract the volume occupied by the hole from the volume of the cuboid in total, 1944 - 162 = 1782 cm³
Answer:
t = 0
Step-by-step explanation:
t - 2 = - 2
t = - 2 + 2
t = 0
