Answer:
see below
Step-by-step explanation:
-33, -27, -21, -15,....
-33 +6 = -27
-27+6 = -21
-21+6 = -15
This is an arithmetic sequence
The common difference is +6
explicit formula
an=a1+(n-1)d where n is the term number and d is the common difference
an = -33 + ( n-1) 6
an = -33 +6n -6
an = -39+6n
recursive formula
an+1 = an +6
10th term
n =10
a10 = -39+6*10
= -39+60
=21
sum formula

The sum will diverge since we are adding infinite numbers
Answer:
<em>The perimeter is 72 units and the area is 149 square units.</em>
Step-by-step explanation:
has coordinates
and
Using the distance formula.........
Length of side
Length of side
Length of side
So, the perimeter of the triangle will be: units. <em>(Rounded to the nearest unit)</em>
The height of the triangle for the corresponding base is 8.89 units.
<u>Formula for the Area of triangle</u>,
So, the area of the will be:
square units. <em>(Rounded to the nearest unit)</em>
