Answer:
75 seconds or 1 minute and 15 seconds
Step-by-step explanation:
300 meters/4 mps = 75 seconds
Answer:
eh+gf/fh
Step-by-step explanation:
<u>Answer:</u>
<u>Answer:Basically, we multiply the numbers altogether and take the nth root of the multiplied numbers, where n is the total number of data values. For example: for a given set of two numbers such as 3 and 1, the geometric mean is equal to √(3×1) = √3 = 1.732.</u>
Answer:
Centre: 
Radius = 
Step-by-step explanation:
General formula for a circle:
, where
the radius of the circle and
is the centre of the circle.
To find the centre and radius of the circle we should re-write the given equation in the form of the general formula.
So, put the terms with the same variables together:

We can see that there is a common factor of
, so let's simplify by dividing by
:

Here we can get it into the general formula by completing the square.
We do this by turning a quadratic with form
into the form
, where d is half of the coefficient of
, e is
and c is the constant of the quadratic.
So let's re-write the equation of the circle:

Simplify: 
Now we can see that it's very similar to the general equation and all we have to do is bring the
over to the right side.

So, now we can find the radius and centre.


The answer should be D. I hope this helps and could I get brainliest please?!
