Write a recursive rule for the sequence an=-4+4n

and

Step-by-step explanation:

The sequence is given by .

Now, putting n = 1, .

Now, putting n = 2,

Therefore, .........(1)

Again, putting n = 3,

Therefore, .......... (2)

Hence, from equations (1) and (2), we can write

and

So, this above relation gives the recursive rule for the given sequence. (Answer)

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
