Answer:
8.2 million years
Step-by-step explanation:
The time can be found from ...
time = distance/speed
time = (47.0×10^4 m)/(5.7×10^-2 m/yr) = 8.2×10^6 yr
It will take about 8.2 million years for LA to have the same latitude as SF.

If the line containing the coordinate "k", is parallel to the line at 5,5 and 1,-4, then their slopes must be the same, since parallel lines, have the same slope, let's check both slopes then.
Answer:
The sample mean is 3.48 and the margin of error is 0.44.
Step-by-step explanation:
We know that the confidence interval is written in the form "x − E to x + E", meaning x: sample mean or estimator, and E: margin of error.
To calculate the mean, we can calculate the average of both bounds of the confidence interval:
With one of the bounds, we can calculate the margin of error E
Answer:
Step-by-step explanation:
Rate of change of x and y can be calculated using the following formula and using any two given pair of values from the table:
Rate of change =
Using (-12, 60) and (-6, 33).
Where,
Plug is the values
Rate of change =
Rate of change =
Simplify
Rate of change =
Rate of change =
