Answer:
2
Step-by-step explanation:
example A(2a,0),B(2b,0)
C(2b,2c),D(2a,2c)
mid point of AC=((2a+2b)/2,(0+2c)/2)=(a+b,c)
mid point of BD=((2b+2a)/2,(0+2c)/2)=(a+b,c)
∴midpoint of diagonals same or diagonals bisect each other.
Answer:
The distance between the Base of the building & the car is x = 83.29 ft
Step-by-step explanation:
Given data
AB = Height of the building = 75 ft
BC = distance from the base of building to the car = x ft
Angle of depression = ∠ BAC = 48°
∠ ACB = 180 - 90 - 48 = 42°
From the Δ ABC
x = 83.29 ft
Therefore the distance between the Base of the building & the car is x = 83.29 ft

Answer:
This sum is the sum of an arithmetic sequence. There is a formula for the sum of an arithmetic sequence which can be looked up or derived by a variety of means.
A nice approach for this sequence is the following. Notice that the sum of first and last number in the sequence is the same as the sum of the second and second last, and also the same as the sum of the third and third last, and so on.
There are n of these pairs. So the desired sum is n x (first number + last number). But the first number is 1 and the last on is 2n. Thus the desired sum is n(1 + 2n).
Hope this helps!!
