Answer:
f(0) = 0.25 = 1/4
f(x) = f(x-1) × 2/3
Step-by-step explanation:
a0 = 0.25×(2/3)⁰ = 0.25×1 = 0.25 = 1/4
a1 = 0.25×(2/3)¹ = 0.25×(2/3) = 1/4 × 2/3 = 2/12 = 1/6 =
= a0 × 2/3
a2 = 0.25×(2/3)² = 0.25×(4/9) = 1/4 × 4/9 = 4/36 = 1/9 =
= a1 × 2/3
=>
an = an-1 × 2/3, n >= 1
but what about negative x ?
is a0 = a-1 × 2/3 ?
so, yes, a0 = a-1 × (2/3)
and a-1 = a-2 × (2/3)

Answer:
The sum of the measures of the interior angles is 900° is False
Each interior angle measures 108° is True
All of the angles are congruent is True
The polygon is a regular hexagon is False
The sum of the measures of the interior angles is 180(5 – 2)° is True
Step-by-step explanation:
A pentagon is a polygon having five sides and equal angles. We can find the sum of the measures of the interior angles through 180*(n-2) where n = 5(number of sides a polygon has)
180*(5-2)= 180(3)=540°
Now the angles are 540/5 = 108°
This shows that the statement:
The sum of the measures of the interior angles is 900° is False
Each interior angle measures 108° is True
All of the angles are congruent is True
The polygon is a regular hexagon is False
The sum of the measures of the interior angles is 180(5 – 2)° is True ....
