I think your answer is B but I’m not sure sorry I hope I helped
Answer:
a)
(i) 43, 56
(ii) -1,3
b)-27
c) -21 +4n
Step-by-step explanation:
For a,i, you can see that it decreses by 7 each time so you subtract 7 from 50 to get 43, then you subtract 7 from that to get 56. For a,ii it increases by 4 each time so you add 4 to -5 to get -1, then add 4 to that to get 3. For b, because it is the 15th term you are looking for, you can plug 15 into the equation as n so 78-7n to 78- 7*15, 78-105, -27. For c, you know that each time it increases by 4, so you know you add 4n, and then for the base, you have to find the term before -17 so you subtract 4 to get -21. Put it together and get -21+4n.
Answer:
24, not Perpendicular
Step-by-step explanation:
4×-6 + 9×7 + -3×5
-24 + 63 - 15
24
Perpendicular when inner product is 0
Answer: See explanation
Step-by-step explanation:
3.) Boys║5║<em>10 ║</em>60
Girls ║7║ 14 ║<em>84</em>
7 × 2 = 14
5 × 2 = 10
5 × 12 = 60
7 × 12 = 84
