(1)
(2)
Where:
- Magnitude.
- Direction, measured in sexagesimal degrees.
If we know that
and
, then complex number in rectangular form is:




The complex number in rectangular form is
.
119.25 is the right answer for this question
Answer:
Pic 1: y=(-3/5)x+4
Pic 2: y=(1/4)x-4
Step-by-step explanation:
TO write the function into vertex form, we need to add one zero and the solution is shown below:
f(x)= x² -6x +1
Add one zero in the form of -9 and 9, such as:
f(x) = x² -6x +1 -9 +9
f(x) = (x² -6x +9) +(1-9)
f(x) = (x-3)² + (-8)
f(x) = (x-3)² - 8
This is the vertex form of the given function and only one zero is being added.
The area of a sector = 0.5 * radius^2 * central angle measure (in radians)
So that:
