Answer:

Step-by-step explanation:
The sequence shown matches that of a geometric sequence of radius 4. To prove it, divide the term
and check that
Then the formula that represents this sequence is:

Where
is the first term of the series = 2 and
is the radius of convergence = 4.
Then the equation is:

Answer:
3. increasing
4. decreasing
Step-by-step explanation:
well for graph 3 the values are increasing
and for graph 4 the values are decreasing
Answer:
x=3.6
Step-by-step explanation:
multiply 4 by 9 and then divide by 10
Answer:
42.86%.
Step-by-step explanation:
Reduction in price = $70.00 - $40.00 = $30.00
Reduction in percentage = ($30.00 ÷ $70.00) x 100 = 42.86%
The price of the videogame was reduced by 42.86%.
