Hello! For this sequence, you are decreasing. In this case, A and C are definitely out, because they are positive, not negative. The formula for sequence is a1 + (n -1)d, where a1 = first term and d = common differnce, The first term is 12 and the common difference is -6. "n" is the order of the sequence and n = 30. 30 - 1 is 29. 29 * -6 is -174. Now, we add 12 to that total and when we add, we subtract the numbers, and then place the negative sign back in. 174 - 12 = 162. Plug in the negative symbol to get -162. There. -162 is the 30th term in the sequence. The answer is D: -162.
Answer:
22 hours = hours travelling altogether
Step-by-step explanation:
11 x 2 = 22
Cos(60) = cos(90 - 30) = sin(30) = 1/2
This should be what you want.
Answer: If i was living there usually , The climate in Ancient Greece generally has hot summers and mild winters. Because it can get so hot, most people wore lightweight clothing throughout most of the year. They would put on a cloak or wrap during the colder days of the winter months. The environment would make a HUGE impact on the Greeks by teaching them how to collect food and survive in a harsh environment. Therefore, I would have to adapt to adapt to their environment efficiently. The environment also affected them because they had to learn to fish instead of hunt on
Step-by-step explanation: This is how I would do it.
X + 1 + X + 1 + X +1+ X +1 = 2X -3+ 2X -3+ X -1+ X -1
4x + 4 = 4x-6+2x-2
4x+4=6x-8
12=2x
6=x
Side lengths:
6-1=5
6+1=7
2(6)-3=9
Hope that helps! Stay safe!
