Answer:
The area of the sumo wrestling ring is
Step-by-step explanation:
The circumference of the circular sumo wrestling ring is , that means its radius
is:
Now once we have the radius of the sumo wrestling ring we can find its area
by the following formula:
Putting in the value of we get:
Therefore the area of the sumo wrestling ring is
Answer:
<em>(–81, 9), (–36, 6), (–1, 1) </em> are the correct three points.
Step-by-step explanation:
Given the function:
Please refer to the attached image.
The green line shows the graph of actual function.
It is reflected over y axis.
The reflected graph is shown in black color in attached image.
When reflected over y axis, the sign of variable changes from Positive to Negative.
So, the resultant function becomes:
i.e. we will have to give the values of x as negative now.
so, the options in which value of x is negative are the possible answers only.
The possible answers are:
(–81, 9), (–36, 6), (–1, 1) and
(–49, 7), (–18, 9), (–1, 1)
Now, we will check the square root function condition.
In the 2nd option, (–18, 9) does not satisfy the condition.
So, the correct answer is:
<em>(–81, 9), (–36, 6), (–1, 1)</em>
