Answer: 214 You added up all of those and devided the mean( all 4)
Distance from a point to a line (Coordinate Geometry)
Method 1: When the line is vertical or horizontal
, the distance from a point to a vertical or horizontal line can be found by the simple difference of coordinates
. Finding the distance from a point to a line is easy if the line is vertical or horizontal. We simply find the difference between the appropriate coordinates of the point and the line. In fact, for vertical lines, this is the only way to do it, since the other methods require the slope of the line, which is undefined for evrtical lines.
Method 2: (If you're looking for an equation) Distance = | Px - Lx |
Hope this helps!
The answer is : Sn = S(n-1) + n
Order of operations (PEMDAS):
21 - 18 <span>/ 3 * 2
let's add some parenthesese to make it easier to see:
21 - (18 / 3 * 2)
multiplication and division are associative
also: 18 / 3 = 18 * (1/3)
21 - (18 * (1/3) * 2)
21 - (6*2) or 21 - (36 * (1/3)) or 21 - (18 * (2/3))
21 - 12

Answer:
Step-by-step explanation:
[...] if you can write the LHS as a perfect square, or if you can't spot a factorization of it right away, if and only if the discriminant (or, if b is an even number, 1/4 of it) is zero.
<u>I see it! I see it!</u>
Stare at it for a while. First term is , third term is , we are missing a double product, but we can play with k. For the LHS to be you just need .
<u>I don't see it...</u>
Then number crunching it is. Set the discriminant to 0, solve for k
