Answer:
5
Step-by-step explanation:
The sum to n terms of a geometric sequence is
=
where a is the first term and r the common ratio
The expression inside the summation is
4 ← the nth term of a geometric sequence
with a = 4 and r = , then
=
=
= ( )
=
= 5
A is true, because if you cross multiply the two fractions, you get 36 = 36. if you cross multiply the other proportions, none of them are equal except A.
There will be infinite answers for x if the equation if the same on both sides, so c=5
Answer:
Step-by-step explanation:
This question is asking you to insert two equations, f(x) and g(x), into the equation g(x) - f(x). This will lead to the equation below.
Now we can solve for the equation.
