Dover is 70 miles due North of the airport, and Oakdale is due east of the airport. If the distance between Dover and Oakdale is 74 miles, how far is Oakdale from the airport? ​

i think the answer is b.

step-by-step explanation:

not 100% sure though.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

step-by-step explanation: 2

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
