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
The smallest degree that you can rotate a pentagon is 36 degrees
C = sqrt(e/m)
You can get this by first dividing away the m and then taking the square root of both sides.
Step-by-step explanation:
y-y₁=m(x-x₁)
1-(-4)=m(4-3)
5=m
Answer:
55
Step-by-step explanation:
Assuming she deposited the same amount each month.
Total ÷ Months = Amount Deposited Each Month
1,320 ÷ 24 = 55
