Hello guys not quite sure this
A= 1/2 of base times height
Answer: $170
Step-by-step explanation:
15% of 200 is equal to $30.
200 - 30 = 170
The answer to the question is 170.
Answer:
<u>Checkmark:</u>
✓ The sequence is geometric
✓ The recursive formula for the sequence is
; 
✓ The explicit formula for the sequence is 
Step-by-step explanation:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by -3 gives the next term.
r = -3

= -2
Substitute the values in the equation:

This is a explicit formula since the next value depends on the position of n (1, 2, 3 .etc)
The recursive formula would be:

Two hundred would be appropriate for a random sample. It doesn't get everyone involved yet has a sustainable amount of people.
