(r,θ) = (x,y)
x = r * cosθ
y = r * sinθ
Since your θ is 5π3, set your calculator to radians before taking the sine and cosine.
(3 cos 5π / 3, 3 sin 5π / 3)
(3* 1 / 2, 3 * - sqrt(3) / 2)
(3 / 2, −3 sqrt (3) / 2)
if r = -3, then x is negative, y is positive.

A=πr2=π×r×r
i well give u 10 points
Answers
Answer:
28.26 units
Step-by-step explanation:
We know the radius of the circle is 3 units, so we'll end up plugging that into the formula.
A = π(3^2) or A = π * 3 * 3
When you substitute pi for 3.14, you'll end up getting 28.26 units.

Still waiting for the server? How does your web browser get a file from the
Internet? Your computer sends a request for the file to a web server, and the web
400 server sends back a response. Let Y = the amount of time (in seconds) after the
start of an hour at which a randomly selected request is received by a particular
web server. The probability distribution of Y can be modeled by a uniform density
curve on the interval from 0 to 3600 seconds. Find the probability that the request
is received by this server within the first 5 minutes (300 seconds) after the hour.
Answers
Answer:
Your computer sends a request for the file to a Web server, and the Web server sends back a response.
Step-by-step explanation:
Using the uniform distribution, it is found that there is a 0.0833 = 8.33% probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour.
----------------------------------
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
The probability distribution of Y can be modeled by a uniform density curve on the interval from 0 to 3600 seconds, thus [tex]a = 0, b = 3600[/tex].
Probability in the first 5 minutes(300 seconds) is:
[tex]P(X < 300) = \frac{300 - 0}{3600 - 0} = 0.0833[/tex]
0.0833 = 8.33% probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour.

We conclude that the 12x is the required expression that is equivalent to 7x + 4x + x and has only one term.
Step-by-step explanation:
Given the expression
[tex]7x+4x+x[/tex]
The current expression has three terms such as 7x, 4x, and x.
The current expression can be further simplified such as
[tex]7x+4x+x[/tex]
Add similar elements: [tex]7x+4x+x=12x[/tex]
[tex]=12x[/tex]
Thus, the given expression [tex]7x+4x+x[/tex] can be expressed as the only one term such as [tex]12x[/tex].
i.e. [tex]7x+4x+x=12x[/tex]
Therefore, we conclude that the 12x is the required expression that is equivalent to 7x + 4x + x and has only one term.

There are 4 white marbles, 6 red marbles, and 2
blue marbles. Once a marble is selected, it is not
replaced. Find the probability of selecting 2 blue
marbles.
Answers
Answer:
For first question, there is 12 marbles at first. So the probability of choosing blue marble is 3/12=1/4. Then marbles are not replaced, the total number is 11. The probability of choosing red is 5/11. So the finally answer is (1/4)*(5/11)=5/44. The same method for second question. Need to notice that you have already choose 1 white marble, so the number of white marble also changed. The answer is (4/12)*(3/11)=1/11.
Step-by-step explanation:
The probability of selecting 2 blue marbles without replacement will be 1/66.
What is probability?Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
There are 4 white marbles, 6 red marbles, and 2 blue marbles.
Once a marble is selected, it is not replaced.
Then the total number of the marbles will be
Total marbles = 4 + 6 + 2
Total marbles = 12
Then the probability of selecting 2 blue marbles without replacement will be
P = 2/12 x 1/11
P = 2/132
P = 1/66
