In your question, you're given the location of three towns, one at point a, one at point b, and one in point c.
00:08
You're given the coordinates for each of those towns, and then you're told about dominique's farm at d, and given the coordinates for that as well.
00:17
In part a, we want to find ad, which is red distance ad.
00:23
To find that, we need to use the distance formula for coordinates on a coordinate plane.
00:28
The distance will equal the square root of our second x value minus our first x value squared, plus our second y value minus our first y value squared.
00:43
So for the coordinates a and d, i'm going to call the coordinates at d x2, y2, and the coordinates at a, x1, y1.
00:55
Now i can plug those values in to the distance formula.
01:01
X2 being 24 minus x1 being 35 squared, plus the second y value is 19 minus y1, which is 26 squared.
01:18
Now at that point, you should be able to type that into a calculator, and we get approximately 13 .0 .0.
01:27
Now your question did not provide any units of measure, so you could just say 13 .04 units.
01:40
And that should be it for part a.
01:43
For part b, the question's asking you to use the nearest neighbor interpolation to estimate the temperature at dominic's farm.
01:53
So basically what that means is we're going to figure out which is the nearest neighbor, a, b, c, and we're going to use that...
