Answer:
B(-1,-3)
Step-by-step explanation:
let the coordinates of B be (x,y)
Mid point of AB = (x₁+ x₂/2, y₁+y₂ /2)
= (-3 +x/2 , -5+y/2)
Mid point of AB is M(-2,-4)
(-3 +x/2 , -5+y/2) = (-2, -4)
-3 + x /2 = -2 ; -5+y/2 = -4
-3 + x = -2 * 2 ; -5 + y = -4 * 2
-3 + x = -4 ; -5 + y = -8
x = -4 +3 ; y = -8 +5
x = -1 ; y = -3
B(-1,-3)
√38
Let's name all the squares.
1² = 1 x 1 = 1
2² = 2 x 2 = 4
3² = 3 x 3 = 9
4² = 4 x 4 = 16
5² = 5 x 5 = 25
6² = 6 x 6 = 36
7² = 7 x 7 = 49
8² = 8 x 8 = 64
Okay that's far enough. Now we look for which numbers 38 is in between.
That would be 36 and 49.
But it's asking for where the square root of 38 is, so √36 and √49 ⇒ 6 and 7.
