Answer: to find velocity, simply put (d2-d1) over (t2-t1) or d/t.

Explanation: To find velocity, divide the change in distance by the change in time. On a graph, pick two points and find the slope of one portion of the line.
Why the slope?
Well this is like your normal x vs. y graph. X being the time and y being your distance.
To find the slope for this, it uses the same formula: (Y2-y1) / (x2-x1)

Hope this helps!!!
BTW, this is physics.

Is − 227 in the sequence below? 13 , 7 , 1 , − 5 , − 11 ,

Papessa [141]

Answer:

Step-by-step explanation:-227 is in The sequence

13,7,1,-5,-11,.....

First term=a=13

Common difference=d=7-13=-6

Checking if -227 is in The sequence

using the formula

Tn=a+dx(n-1)

-227=13+(-6)x(n-1)

-227=13-6n+6

collect like terms

6n=13+6+227

6n=246

Divide both sides by 6

6n/6=246/6

n=41

Therefore -227 is the 41ist term Of The sequence
