Answer:

Step-by-step explanation:
The explicit formula for an arithmetic sequence is given by :
...(1)
We need to find the 200th term of the sequence.
Put n = 200 in equation (1)

So, the 200th term of the sequence is 418.
Answer is below. Look at my explanation to understand my answer.
To convert centimetres into meters, you'll divide how many centimetres by 100.
With that being said...
674 ÷ 100 = 6.74
Hence, 6.74 is your answer.
Let me know of any questions or concerns.
B. 9 I think because it looks like it is bisected in the middle to cut into two equal parts. Please correct me if I am wrong. Thanks.
Basically, Justin and Tina's paths form two right-angled triangles whose hypotenuses(?) form a straight line between their end points. Therefore we need to find the two distances from the starting point and add them.
Justin walked 3 miles north and 6 miles west so his distance from the start is the square root of 9+36 or 45. This can be simplified to 3√5.
Tina walked 2 miles south and 4 miles east so her distance from the starting point is the square root of 4 + 16 or 20. This can be written as 2√5.
If we add these two distances together we get 5√5. Hence, Justin and Tina are 5√5 miles away from each other.
Hello there!
The statement that would NOT be true would be option A. All isosceles triangles are also equilateral triangles. The rest of the statements would be TRUE.
Hope this helps and have a great day! :)
