Answer:
Step-by-step explanation:
B(2,10); D(6,2)
Midpoint(x1+x2/2, y1+y2/2) = M ( 2+6/2, 10+2/2) = M(8/2, 12/2) = M(4,6)
Rhombus all sides are equal.
AB = BC = CD =AD
distance = √(x2-x1)² + (y2- y1)²
As A lies on x-axis, it y-co ordinate = 0; Let its x-co ordinate be x
A(X,0)
AB = AD
√(2-x)² + (10-0)² = √(6-x)² + (2-0)²
√(2-x)² + (10)² = √(6-x)² + (2)²
√x² -4x +4 + 100 = √x²-12x+36 + 4
√x² -4x + 104 = √x²-12x+40
square both sides,
x² -4x + 104 = x²-12x+40
x² -4x - x²+ 12x = 40 - 104
8x = -64
x = -64/8
x = -8
A(-8,0)
Let C(a,b)
M is AC midpoint
(-8+a/2, 0 + b/2) = M(4,6)
(-8+a/2, b/2) = M(4,6)
Comparing;
-8+a/2 = 4 ; b/2 = 6
-8+a = 4*2 ; b = 6*2
-8+a = 8 ; b = 12
a = 8 +8
a = 16
Hence, C(16,12)
The answer is C to this question

Answer:
The % Alicia speed walking is 125 % of average walking
Step-by-step explanation:
Given as :
Distance cover by Alicia while walking = 4 miles
Time taken = 1 hour
So, Speed of Alicia while walking =
Or, S 1 =
I.e S 1 = 4 mph
And
Distance cover by Alicia while speed walk = 5 miles
Time Taken = 1 hour
So, Speed of Alicia while speed walking =
Or, S 2 =
I.e S 2 = 5 mph
Or, % Rate =
×100 = 125
Hence The % Alicia speed walking is 125 % of average walking Answer
B. 4 1/4 <_ 2K because the point of the arrow is going to the less amount and when you ad the line under it, that makes it equal to or less than. In other words no more than.
