It's pretty simple. What you should tell is:
The car has lost half of it's speed for first 3 seconds of movement (from 4 mi/h down to 2 mi/h). Then it became moving in 2.5 times faster for next 2 seconds (from 2 mi/h up to 5 mi/h) and after that it was moving at constant speed (5 mi/h).

Graph each circle given below right the center and radius of each circle

expeople1 [14]

Answer:

Center: (-3,-2)

Radius: √6

The graph is attached.

Step-by-step explanation:

The equation of the circle has the form:

$(x -h)^{2}+(y-k)^{2}=r^{2}$

Where (h,k) is the point of the center of the circle and r is the radius of the circle.

The equation given in the problem is

$(x +3)^{2}+(y+2)^{2}=6$

Therefore:

h=-3

k=-2

The center is at (-3,-2)

And the radius is:

$r^2=6\\r=\sqrt{6}$

Then, you can graph it has you can see in the image attached.

The quotient of negative eight and the sum of a number and three

PolarNik [594]

For this case, the first thing we must do is define a variable.
We have then:
x: real number
Now we write the expression:
-8 / (x + 3)
The number x can be all real different from minus three.
Answer:
