Answer:
- Translation
Step-by-step explanation:
Movement of a rigid object from one place to another without any turning is "translation." If the object also changes its orientation angle, then rotation is involved.
Answer:
46
Step-by-step explanation:
Cos 210° = cos ( 180° + 30° ) - cos 30° = - √3/2
Rule needed: i^2 = -1
Standard form a + bi
(3 + 2i)(7 - 5i) FOIL
3 * 7 = 21
3 * - 5i = - 15i
2i * 7 = 14i
2i * -5i = - 10i^2 = - 10 * -1 = 10
Putting it all back together.
31 - i
Ya I like the first one better than the second one but both are good
