Step-by-step explanation:
I'll presume the sequence is arithmetic, simply because assuming the series is mathematical, there is more than one solution.
Assuming the series is comprised of numbers in an arithmetic progression, you will have... (see attachment for better explanation and step by step.)
Answer:
Ф lies in the 2nd quadrant
Step-by-step explanation:
1. If angle Ф lies in the 1st quadrant, then
- sin Ф is a positive value
- cos Ф is a positive value
- tan Ф is a positive value
2. If angle Ф lies in the 2nd quadrant, then
- sin Ф is a positive value
- cos Ф is a negative value
- tan Ф is a negative value
3.If angle Ф lies in the 3rd quadrant, then
- sin Ф is a negative value
- cos Ф is a negative value
- tan Ф is a positive value
4. If angle Ф lies in the 4th quadrant, then
- sin Ф is a negative value
- cos Ф is a positive value
- tan Ф is a negative value
∵ sec Ф < 0
∴ sec Ф is a negative value
∵ cos Ф = 1/sec Ф
∴ cos Ф is a negative value
∵ csc Ф > 0
∴ csc Ф is a positive value
∵ sin Ф = 1/csc Ф
∴ sin Ф is a positive value
→ By using the second rule above
∴ Ф lies in the 2nd quadrant
Answer:
134
Step-by-step explanation:
There's 2 blue arrows where 39 is, and the same arrows where 4x+7 are. This means that they are the same length. So, 4x+7 = 39. Perimeter means you add, so 28+28+39+39 = 134.
