Any complex number
can be written in trigonometric form as

where
is the modulus of
and
is its argument, i.e. the angle
makes with the positive real axis in the complex plane.
We have

and

Then

Answer: d. The domain would only include positive numbers.
Step-by-step explanation:
Given: A function is created to represent the miles per gallon your car gets.
Here, the independent variable = the amount of fuel the car gets in gallons.
and the dependent variable = the total miles of car travel .
We know that the domain of a function is a set of all values of independent variable.
Thus, the domain would only include positive numbers because the quantity of fuel in a car is never negative and it can be in fraction .
Hence, D is the right answer.
Answer:
The number of times coin thrown was <u>500</u>.
Step-by-step explanation:
Given:
A coin lands on heads 200 times. the relative frequency of heads is 0.4.
Now, to find the times coin was thrown.
Let the number of times coin thrown was be 
Relative frequency = 0.4.
Number of lands on heads = 200.
So, to get the number of times coin was thrown we put formula:


<em>By cross multiplying we get:</em>

<em>Dividing both sides by 0.4 we get:</em>

Therefore, the number of times coin thrown was 500.
Each person will get 5.33 pound of turkey.
-ratio
-interval
-nominal
-ordinal
Answer:
Nominal
Step-by-step explanation:
-Ratio level of measurement means that you can build a fraction.
-interval level of measurement means that the distance that exists between values is important.
-Nominal means that the values are only named and there is no organization.
-Ordinal means that the values can be ordered by rank.
According to this, the answer is that classifying the fruit in a basket as apple, orange, or banana, is an example of the nominal level of measurement.
