Given:
The equation of circle is
To find:
The polar form of given circle.
Solution:
We have,
![[\because (a+b)^2=a^2+2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%2Bb%29%5E2%3Da%5E2%2B2ab%2Bb%5E2%5D)
Subtracting 9 from both sides, we get
We know that, 
and 
.
and 
We know that, r is radius it cannot be 0. So,
Therefore, the correct option is A.
A line plot can be used as a data display for the distribution of test scores in math class. Thus, the option to choose is <u>TRUE</u>.
A line plot is a graph that shows data as checkmarks or dots across a number line, indicating the frequency of each value.
The test score in the math test will be discrete data with repeating frequencies. The score of every individual will moreover be a whole number.
The line plot, as we know, marks the dots across the number line, indicating frequency.
Thus, the scores in the math test can be displayed using a line plot, by indicating each type of mark on the line, and dots above those marks for the number of times the same marks occur.
Thus, the option to choose is <u>true</u>.

We use the formula : Displacement = Average Velocity * Time ;
17 = ( v + 8 ) * t ;
1 = ( v - 8 ) * t ;
where v = the velocity of the boat; t is the time from expression " ... in the same amount of the time he rows ....."
Then 17 / 1 = (v + 8) / ( v - 8 ) ;
v + 8 = 17( v - 8 );
v + 8 = 17v - 136 ;
144 = 16v ;
v = 144 / 16;
v = 9 mph ;
18 = 9 * x ;
x = 18 / 9 ;
x = 2 hours ;
The answer is 2 hours ;
Answer:
Figure A
Step-by-step explanation:
A regular polygon is a polygon that has equal sides and angles.
By looking at the choices you can see the Rhombus or square has all equal sides and all angles are the same.
Hope this helps!
