Answer:

9 units

Center is at (5, 0)

Step-by-step explanation:

The radius of the circle is equal to the square root of 81

\sqrt{81} = ±9

Since the radius of a circle must be positive the answer is 9 units.

The center of the circle is at (5, 0)

The motion of an object was recorded by measuring the velocity of the object in meters per second at various times, as shown in
Komok [63]

The equation BEST represents the relationship between velocity and time is y = 2.2x + 6.

According to the statement

we have given some data in the form of graph according to the velocity per time and we have to find the relationship between the velocity and time.

So, for this purpose,

we know that the best method show the relationship is a slope intercept form.

So,

The slope intercept form is a the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.

And

Using the coordinate points on the plane (0, 6) and (10, 28)

now we Determine the slope

Slope = 28-6/10-0

Slope = 22/10

Slope = 2.2

And then Determine the y-intercept

6 = 2.2(0) + b

b = 6

And now we have to put in the general form of the slope intercept form which is y = mx + b

Then the equation become

y = 2.2x + 6

So, The equation BEST represents the relationship between velocity and time is y = 2.2x + 6.

Firlakuza [10]

Answer:

5/10=u/9

explain answer: so to get this answer 5x8=40 so like the closes number to eight will be 9 and 10 but they said closes 10 so it will be 5/10 and =u/9 so answer= 5/10=u/9
