Answer:
A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
Step-by-step explanation:
By definition, Acceleration is the rate of change of Velocity of an object.
I.e it is the( final velocity minus initial velocity ) ÷ by the time it took for the velocity to change.
If we observe the choices only one choice gives us all 3 components (final velocity, initial velocity, time taken for velocity to change), which is :
A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
what is your question then?
The transformations that would prove that circles A and C are similar are:
- A. Reflect A over the line y=x
- C. Dilate A by 3/2
<h3>How to prove that circle A and circle C are similar?</h3>
The circles are given as:
Circle A and B
Assume the following parameters:
- The center of circle A is (2,3) with a radius of 2
- The center of circle B is (3,2) with a radius of 3
To start with;
The circle A must be reflected across the line y = x with the following transformation rule:
(x,y) -> (y,x)
So, we have:
(2,3) -> (3,2)
Next, the radius of A must be dilated by 3/2 as follows:
New Radius = 3/2 * 2 = 3
After the transformations, we have the following parameters:
- The center of circle A is (3,2) with a radius of 3
- The center of circle B is (3,2) with a radius of 3
Notice that both circles now have the same center and radius.
Hence, both circles are similar

Answer:
-12, -11, 4, 12
Step-by-step explanation:
A negative number is less the higher it is, and a positive number is more the higher it is
The answer would be -5a+3b
3a+(-8a)=-5a
2b+b=3b
