Answer:
See explanation
Step-by-step explanation:
Consider the sequence 
Rewrite it as
The points on the coordinate plane are
(see attached graph).
Since
given sequence is geometric.
Answer:
The maximum point of this function is (5,4).
Step-by-step explanation:
The maximum of a function is the maximum value that it can take.
Seeing the graph we can say that the maximum value of y occurs at x = 4. Here y = 5 corresponds to this value of x.
Therefore, the maximum point of this function is (5,4).

Step-by-step explanation:
Answer:
Adult=58
Step-by-step explanation:
c=child, a=adult
6.4c+9.7a=1145 equation 1
c+a=149 equation 2
a=149-c modified equation 2 to isolate a
6.4c+9.7(149-c)=1145 substitute value of a from equation 1 into equation 2
6.4c+1445.3-9.7c=1145
-3.3c=-300.3
c=91
solve for a
c+a=149
91+a=149
a=58
Check answer:
6.4c+9.7a=1145
6.4(91)+9.7(58)=1145
582.40+562.60=1145
1145=1145
