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

Answer:
155answer.
Step-by-step explanation:
25 is 80 and thaths why its 157
mean would be adding them all up and dividing by how many there is mean median mode and range but the mean absolute deviation would be actually can't tell you cuz I don't know myself but you could probably look it up I wish you the best of luck
