The center of the equation of the circle will be (h, k) = ( -3. -1).
<h3>What are a circle and its equation?</h3>
A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at (h,k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
We have been given an equation of the circle as
By comparing the equation with general equation of the circle
we get,
h = -3
k = -1
r = 3
So, the center of the equation will be (h, k) = ( -3. -1).

Let me know if I’m right
Answer:
a) The modal average is 3 bedrooms
b) The mean number of bedrooms is 2.825, or 3 rounded.
Step-by-step explanation:
If you lay out all the numbers from lowest to highest, and find the one in the middle, it is 3 bedrooms.
For the mean, if you add up all the number of bedrooms then divide by the total frequency, you get 2.825. This would be 113 ÷ 40.
The area of the given triangle is <u>84 cm²</u>.
The area of any two-dimensional figure is the space occupied within its boundary.
The area of a triangle is calculated using the formula, A = (1/2)*b*h, where A is its area, b is the length of its base, and h is the length of its height.
In the question, we are asked to find the area of the given triangle.
The length of the base of the given triangle, b = 21 cm.
The length of the height of the given triangle, h = 8 cm.
We can calculate the area of the given triangle, using the formula, A = (1/2)*b*h, where A is its area, b is the length of its base, and h is the length of its height.
A = (1/2)*(21)*(8) cm²,
or, A = 84 cm².
Thus, the area of the given triangle is <u>84 cm²</u>.
