Find all polar coordinates of point P = (2,14°)

Answers

Answer 1
Answer:

Answer:

(2,14^(\circ)+360^(\circ)n)\text{ and }(-2,194^(\circ) +360^(\circ)n).

Step-by-step explanation:

If a point is P=(r,\theta), the all polar coordinates are defined as

In radian : (r,\theta +2n\pi)\text{ and }(-r,\theta +(2n+1)\pi)

In degree : (r,\theta +360^(\circ)n)\text{ and }(-r,\theta +(2n+1)180^(\circ))

where, n is any integer.

The given point is

P=(2,14^(\circ))

So, all polar coordinates are  

(2,14^(\circ)+360^(\circ)n)\text{ and }(-2,14^(\circ) +(2n+1)180^(\circ))

(2,14^(\circ)+360^(\circ)n)\text{ and }(-2,14^(\circ) +360^(\circ)n+180^(\circ))

(2,14^(\circ)+360^(\circ)n)\text{ and }(-2,194^(\circ) +360^(\circ)n)

Therefore, the required polar coordinates are (2,14^(\circ)+360^(\circ)n)\text{ and }(-2,194^(\circ) +360^(\circ)n), where n is any integer.

Hello there! Here are your answers:

Does Kerri's dot plot match the data in the tally table? No.

Look at any of the hours on the chart vs dot plot. Let's take 4 for example. In the tally table, there are 6 class mates. In the plot, there are 3. So no, it is not the same.

The answers for the other problems are in this order (since it's the number of circles on the dot plot at the given hour):

5 - classmates spent 3 hours at the park

3 - classmates spent 4 hours at the park

6- classmates spent 5 hours at the park

4 - classmates spent 6 hours at the park

I hope this was helpful and let me know if you need more help! :) Have a great day! :)

What percent of 100 is 30?
a. 30%
b. 333%
c. 3.33%
d. 0.3%

Answers

If you would like to know what percent of 100 is 30, you can calculate this using the following steps:

x% of 100 is 30
x% * 100 = 30
x/100 * 100 = 30
x = 30%

The correct result would be a. 30%.
We set up a proportion: 30/100= ?/100

Because we have the same denominator, the two numerators must be equivalent.

Therefore, ?= 30.

The correct answer is a. 30%

10x 10y = 1 x = y - 3 what is the value of y?

Answers

Solve the equations by substitution. If the equations are inconsistent and the solution is an empty set, write "no solution". 
10x - 10y = 1 
x = y - 3 
10x - 10y = 1
x = y - 3
The second equation is solved for x, Sosubstitute (y - 3) for x in the first equation10x - 10y = 1
10(y - 3) - 10y = 1
 10y - 30 - 10y = 1-30 = 1
 The y's all canceled out and left a false numerical equation,-30 in not equal to 1, so there is no solution. The system is called aninconsistent system of equation.
