18. GOLF Luis and three friends went golfing. Two of the friends rented clubs for $6 each. The total cost of the rented
1 answer:
Answer:
The cost of the green fees for each person was $16
Step-by-step explanation:
Let
x -----> the cost of the green fees for each person
we know that
The total cost of the green fees plus the green fees for each person must be equal to $76
so
The linear equation that represent this problem is
Solve for x
Subtract 12 both sides
Rewrite
therefore
The cost of the green fees for each person was $16

You haven't provided the series, therefore, I can only help with the concept.
<u><em>For an infinite geometric series, we have two possibilities for the common ratio (r):</em></u>
for r > 1, the terms in the series will keep increasing infinitely and the only possible logic summation of the series would be infinity
for r < 1, the terms will decrease, therefore, we can formulate a rule to get the sum of the infinite series
<u><em>In an infinite series with r < 1, the summation can be found using the following rule:</em></u>
sum =
where:
a₁ is the first term in the series
r is the common ratio
<u>Example:</u>
For the series:
2 , 1, 0.5 , 0.25 , ....
we have:
a₁ = 2
r = 0.5
Therefre:
sum =

We know the following relationship:
The domain of a function are the inputs of the function, that is, a function
is a relation that assigns to each element 
in the set A exactly one element in the set B. The set A is the domain (or set of inputs) of the function and the set B contains the range (or set of outputs).Then applying this concept to our function 
we can write its domain as follows:
1. D<span>omain of validity for:

when:
where k is an integer either positive or negative. That is:
To match this with the choices above, the answer is:
