Answer:
Step-by-step explanation:
Given that:
Speed of Wilmer up the hill = km/min
Time taken up the hill = minutes
Speed of Wilmer down the hill = km/min
Time taken up the hill = minutes
Distance can be calculated by multiplying the Speed with Time i.e.
The formula for distance is given as:
Distance up the hill =
Distance down the hill =
It is well known that, the distance up the hill and down the hill will be same.
Putting both the values equal, we get:
Answer:
We kindly invite you to see the result in the image attached below.
The number in polar form is .
Step-by-step explanation:
A complex number is represented by elements of the form , for all
,
. The first part of the sum is the real component of the complex number, whereas the second part of the sum is the imaginary component of the complex number. The real component is located on the horizontal axis and the imaginary component on the vertical axis.
Now we proceed to present the point on the graph: (,
) We kindly invite you to see the result in the image attached below.
The polar form of the complex number is defined by:
(1)
Where:
- Magnitude of the complex number, dimensionless.
- Direction of the complex number, measured in radians.
The magnitude and the direction of the complex number are defined by the following formulas:
Magnitude
(2)
Direction
(3)
If we know that and
, then the polar form of the number is:
The number in polar form is .
