Simplify by combining like terms.
-6x + 17
-6x + 17
Answer:
4560
Step-by-step explanation:
Well, first we need to understand how different time formats (for lack of a better word) are related in terms of seconds.
1 minute has 60 seconds
I hour has 3600 seconds
1 day has 86400 seconds
1 week has 604800 seconds
Now, with this information at hand, you can find out how many seconds are in X minutes or X days or X months or a year (and so on).
As for your question, we know that one minute has 60 seconds therefore 76 minutes will have (76x60) seconds
A. If you plot the points in a graph, it would look like that shown in the picture attached. If we use linear regression, the correlation is very poor. The coefficient of correlation (r2) is only 0.0017. There is no linear relationship between time and velocity.
B. The slope of the graph is equal to y2-y1/x2-x1, In this case, it would specifically be v2-v1/t2-t1
Slope = 0.8-0.2/20-10 = 0.06 miles/s^2
The slope represents the acceleration at time 10 to 20 minutes.
C. The table in the graph shows causation rather than correlation. The points in the data occur in a sequential manner.
