The original functions are: f(n) = 500 and g(n) = [9/10]^(n-1)
A geometric sequence combining them is: An = f(n)*g(n) = 500*[9/10]^(n-1):
Some terms are:
A1= 500
A2 = 500*[9/10]
A3 = 500*[9/10]^2
A4 = 500*[9/10]^3
....
A11 = 500*[9/10]^10 ≈ 174.339
Answer: the third option, An = 500[9/10]^(n-1); A11 = 174.339

Answer:
23.44
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation ...
Tan = Opposite/Adjacent
tan(38°) = x/30
x = 30·tan(38°) ≈ 23.4386
x ≈ 23.44
Based on the points on the graph, the correct matches are:
- A - (-4, -2).
- B - .(2, -4)
- C - (4, -2).
- D - (2, 5)
- E - (-1, 1)
- F - (-5, 0)
- G - (4, 2)
- H - (0, -5)
<h3>How are points located on a graph?</h3>
To find a point, you need to look at the x-axis first and then the y-axis.
Find where the point is located on the x-axis, and then look for where the point intersects with the y-axis point.
For instance, the point A is located at (-4, -2) so look at the -4 point on the x axis, then go down to the -2 point on the y-axis. You'll find point A.
