hopefully this helped!!!!!
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
The answer to this problem is 1 and 5 tenths.
Answer:
Step-by-step explanation:
(d - 8)/5 = p
d - 8 = 5p
d = 5p + 8
Answer:
The answer to your question is (f°g)(x) = -5856x⁶ - 25529x⁴ -52710x² - 36220
Step-by-step explanation:
Data
f(x) = -12x³ + 19x² - 5
g(x) = 7x² + 15
find (f°g)(x)
Process
1.- Substitute g(x) in all the x of f(x)
(f°g)(x) = -12(7x² + 15)³ + 19(7x² + 15)² - 5
-Expand
(f°g)(x) = -12[4913x⁶ + 2205x⁴ + 4725x² + 3375] + 19(49x⁴ + 210x² + 225) - 5
-Simplify
(f°g)(x) = -58956x⁶ - 26460x⁴ - 56700x² - 40500 + 931x⁴ + 3990x² + 4275 -
5
-Result
(f°g)(x) = -5856x⁶ - 25529x⁴ -52710x² - 36220
