Because the speed has formula of distance divide time = m/s
and the acceleration is speed /time so (m/s)/s = m/(s*s) = m/s^2
hope this is understandably sure easy for you 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
To solve this operation we need to find the common multiple of both denominators and solve for a. 

Thus, the solution is 7(a -1) / (a+2)(a-5)
 
        
             
        
        
        
Answer:
43,300
Step-by-step explanation:
Starting with 2 since its in the hundredths and going over one place to the tenths, we see 7 <em>is </em> greater than 5 so we make the 2 a 3 and replace everything after with 0's
43,300!!
 
        
             
        
        
        
Answer:
   diameter = m - c
Step-by-step explanation:
In ΔABC, let ∠C be the right angle. The length of the tangents from point C to the inscribed circle are "r", the radius. Then the lengths of tangents from point A are (b-r), and those from point B have length (a-r).
The sum of the lengths of the tangents from points A and B on side "c" is ...
   (b-r) +(a-r) = c
   (a+b) -2r = c
Now, the problem statement defines the sum of side lengths as ...
   a+b = m
and, of course, the diameter (d) is 2r, so we can rewrite the above equation as ...
   m -d = c
   m - c = d . . . . add d-c
The diameter of the inscribed circle is the difference between the sum of leg lengths and the hypotenuse.
