DeMoivre's theorem says
(2 (cos(12°) + <em>i</em> sin(12°)))⁵ = 2⁵ (cos(5×12°) + <em>i</em> sin(5×12°))
… = 32 (cos(60°) + <em>i</em> sin(60°))
… = 32 (1/2 + √3/2 <em>i</em> )
… = 16 + 16√3 <em>i</em>

Answer:

Step-by-step explanation:
-The total portion fed to the dog is 7/10 cup
- Canned-3/10
- Dry=7/10-3/10=4/10
-One week has 7 days. we multiply the dry portion per day by the number of days in a week.

Hence, Erin feed her dog 2 4/5 0r 2.8 cups of dry food
