Answer:
The vertex is ( -4,1)
Step-by-step explanation:
The equation for a parabola can be written as
y = a( x-h)^2 +k where ( h,k) is the vertex
y = 2
(x + 4)² + 1
Rewriting
y = 2
(x - -4)² + 1
The vertex is ( -4,1)
The recursive geometric sequence that models this situation is:


<h3>What is a geometric sequence?</h3>
A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
It can be represented by a recursive sequence as follows:

With f(1) as the first term.
In this problem, the sequence is: 90.000: 81,000; 72,900; 65,610, hence:


Hence:

Answer:
1 hour= 45 miles
1/2 hour=22.5 miles
3 hours= 135
Step-by-step explanation:
just work out one hour by halving 90 miles which is 45. Then work out the rest by halving again and multiplying by 3.
