Assume that an airplane is flying toward you at a constant height h = 1 mile and at a speed dxdt=−20 miles/hr. When the plane is 2 miles away, what is the rate of change of θ?

tan(θ)=h/x

A. dθ/dt=−6 degrees/second

B. dθ/dt=−4 degrees/second

C. dθ/dt=4 degrees/second

D. dθ/dt=6 degrees/second

the answer is 489

step-by-step explanation:

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
