Answer:
= - 4
Step-by-step explanation:
Note the common ratio r between consecutive terms in the sequence, that is
- 16 ÷ - 4 = - 64 ÷ - 16 = - 256 ÷ - 64 = 4
This indicates the sequence is geometric with n th term ( explicit formula )
= a
where a is the first term and r the common ratio
Here a = - 4 and r = 4, thus
= - 4 ← explicit formula
Answer: (x,y) (-y,x)
Step-by-step explanation:
Answer: The discount is $180, and the price with the discount is $1,020.
Step-by-step explanation: Multiply 1,200 times .15 to get the discount, or how much you get off. Then subtract the answer, which is $180, from the original price, to get $1,020. This is the price with the discount.
1) 6/11
2) 5/27
3) 42/11 or 3 9/11
4) 50/121
The answer would be the first one. 15 times 8 is 120, and 15 times 60 is 900 so it is one.
