For any arithmetic sequence aₙ₊₁ = aₙ + d
912, 864, 816, 768, 720
864 - 912 = -48 = d
so the next three terms:
720 + (-48) = 672
672 + (-48) = 624
624 + (-48) = 576
670, 620, 570 ⇒ 620 - 670 = -50 = d
so the next three terms:
570 + (-50) = 520
520 + (-50) = 470
470 + (-50) = 420
620, 520, 420 ⇒ 520 - 620 = -100 = d
so the next three terms:
420 + (-100) = 320
320 + (-100) = 220
220 + (-100) = 120
672, 624, 576 ⇒ 624 - 672 = -48 = d
so the next three terms:
576 + (-48) = 528
528 + (-48) = 480
480 + (-48) = 432
675, 630, 585 ⇒ 630 - 675 = -45 = d
so the next three terms:
585 + (-45) = 540
540 + (-45) = 495
495 + (-45) = 450
Right off the bat, this may look crazy, but if we take it step by step, it will be much easier. So, let's take it step by step. If any step doesn't make sense to you, you can always hmu.
Your answer is
69.
Answer:
(-8, 6)(-8, 6)
Step-by-step explanation:
The formula for 180 degree rotation is (-x, -y)
Use the folumla AB^2 = BD * (CD + BD)
fill in the known numbers:
AB^2 = 12 x (15 +12)
AB^2 = 12 x 27
AB^2 = 324
AB = SQRT(324)
AB = 18
