Answer:
The answer to your question is dAB = 10.63
Step-by-step explanation:
Data
A = (7, 3)
B = (-1, -4)
Process
To solve this problem, use the formula of the distance between two points, substitute the values and simplify.
Formula
dAB =
x1 = 7 y1 = 3 x2 = -1 y2 = -4
-Substitution
dAB =
-Simplification
dAB =
dAB =
dAB =
-Result
dAB = 10.63
Question: Please help lily team won 8 out of 12 games.At that rate,how many games will her team win if it plays 21 games?The ratio is now: 8 : 12 = X : 21, where x is the unknown value of win they have and 21 is the total number of games they played=> 8 : 12 = x : 21=> 8 * 21 = 168 / 12 = 14Thus, the new ratio is 8 : 12 and 14 : 21they will be winning 14 games out of 21 plays<span>

D = sqrt (x2 - x1)^2 + (y2 - y1)^2
d = sqrt (-8-7)^2 + (-9-(-1)^2
d = sqrt (-15^2)^2 + (-8^2)^2
I am getting : (-15^2) + (-8^2)
