Here are some examples of equivalent ratios for 1/6:
2:12, 3:18, 4:24, 5:30, 6:36
All of these simplify to 1/6, which makes them equivalent. Hope this helps! :)
The first choice is the contains only irrational number
Answer: the rate at which its altitude is changing is -47 ft/s
Step-by-step explanation:
Given that;
ds/dt = 45 mph = 45 × 5280/3600 = 66 ft/sec
no we have to determine dx/dt
so
cos∅ = dx/dt / ds/dt
cos45° = dx/dt / 66
dx/dt = 0.7071 × 66
dx/dt = 46.6686 ≈ 47 ft/s ( as altitude is decreasing, its negative - )
so the rate at which its altitude is changing is -47 ft/s
