The second and third ones are the true ones
Answer:
Step-by-step explanation:
a₁ = -3 = (-1)¹×3
a₂ = 6 = (-1)²×2×3
a₃ = -28 = (-1)³×2²×7
a₄ = 72 = (-1)⁴×2³×3²
a₅ = -360 = (-1)⁵×2³×3²×5
a₆ = 2160 = (-1)⁶×2⁴×3³×5
That's as far as I got. I can predict that a₇ is a multiple of -32 and a₈ is a multiple of 64, but I don't see the pattern with the other factors.
Answer:
Beam stick out = 2.09 ft
Step-by-step explanation:
Given:
Length of wooden beam = 12 ft
Side of bed = 5.5 ft by 8 ft by 2 ft
Find:
Length of wooden beam needed.
Computation:
Length of wooden beam needed = 9.91 ft
Beam stick out = 12 ft - 9.91 ft
Beam stick out = 2.09 ft
Answer:
45.7 s
Step-by-step explanation:
Darya:
Number of laps = 13
Average time per lap = 23.5 seconds
Total time to swim 13 laps = Number of laps × Average time per lap
= 13 × 23.5
= 305.5 seconds
Kana:
Number of laps = 10
Average time per lap = 25.98 seconds
Total time to swim 10 laps = Number of laps × Average time per lap
= 10 × 25.98
= 259.8 seconds
It took longer for Darya to swim
13 laps than for Kana to swim 10 laps.
How much longer?
= 305.5 seconds - 259.8 seconds
= 45.7 seconds
