Answer:
-2 m/s^2
Step-by-step explanation:
Just as you would calculate the velocity when a body moves from point A to point B in a time T, we are going to calculate the acceleration as the difference of the velocities (final - initial) and divide it by the time it took:
Velocity_final = 10 m/s
Velocity_initial = 20 m/s
Time = 5 s
acceleration = (Velocity_final -  Velocity_inital)/Time
                      = (10 m/s - 20 m/s)/5 s
                      = (-10 m/s) / 5s
                      = -2 m/s^2
The acceleration in m/s^2 is -2
 
        
             
        
        
        
Answer:
x = - 1
Step-by-step explanation:
Given
4x = x^2 - 5               Transfer 4x to the right side.
Solution
x^2 - 4x - 5 = 0          Factor
(x - 5)(x + 1)
You want the negative solution. That means that the middle sign must be plus.
x + 1 = 0                   Subtract 10 from both sides
x = - 1                       Ten on the left disappears by the subtraction process.
Is that correct?
4x = x^2 - 5
x = - 10
4*(-1) = (-1)^2 - 5
-4  = ? 1 - 5
-4 = - 4 
and it does work.   
 
        
             
        
        
        
Answer:
True
Step-by-step explanation:
The reason I say this is because of the fact you can't go into retirement without knowing how much your going to get. You need to create a financial plan stating how much you will get and how much you have saved prior to this occurence.

The graph is misleading because the sizes compared to the percentages are off. a more appropriate way to show the data would be with a bar graph.
Hope this helps!

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
