Answer:
21/28
Step-by-step explanation:
Are there any answer choices?
-21 + 28x = 0
28x = 21
Divide by 28
x = 21/28
I believe that the answer may be 1,1,1,2

What is the recursive formula for this geometric sequence 2, -10, 50, -250, .... ?
The recursive formula for this geometric sequence is:
= 2;
= (-5) • 
Step-by-step explanation:
To find the recursive formula for a geometric sequence:
- Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
- Find the common ratio. (The number you multiply or divide.)
- Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.
The recursive formula is:
= first term;
= r •
, where
is the first term in the sequence
is the term before the nth term - r is the common ratio
∵ The geometric sequence is 2 , -10 , 50 , -250
∴
= 2
- To find r divide the 2nd term by the first term
∵ 
∴ 
- Substitute the values of
and r in the formula above
∴
= 2;
= (-5) • 
The recursive formula for this geometric sequence is:
= 2;
= (-5) •

Answer:
B&C: tan F=0.0833 & tan H=12.0000
Step-by-step explanation:
The tangent relationship is always opposite/adjacent.
When F is the reference angle, side GH (1) is the opposite side and side FG (12) is the adjacent.
1/12 is 0.0833
When H is the reference angle, FG (12) is the opposite and GH (1) is the adjacent.
12/1 is 12.
