Answer:
Step-by-step explanation:
Given complex number is:
To find:
Answer in rectangular form after using De Moivre's theorem = ?
i.e. the form (not in forms of angles)
Solution:
De Moivre's theorem provides us a way of solving the powers of complex numbers written in polar form.
As per De Moivre's theorem:
So, the given complex number can be written as:
Now, using De Moivre's theorem:
So, the answer in rectangular form is:
Answer:
70%
Step-by-step explanation:
7/10 × 100% = 70%
The male lion weighs 70% more than the female lion.
Answer:
6 units
Step-by-step explanation:
One side of the triangle is 4 cm, since the chord is 4 units away from the center, and the hypotenuse is 5 cm. To find the remaining side, we use the pythagorean theorem, 5^2-4^2=remaining side^2, remaining side = 3. To get the length of the chord, we double 3 and get 6 units.
Answer:
-1/9
Step-by-step explanation:
m=y2-y1/x2-x1
3-4=(-1)
10-1=9
-1/9
