What is the distance between (-5, 4) and (-1.4)?

The distance between (-5, 4) and (-1, 4) is 4 units

Step-by-step explanation:

To solve this problem we first have to calculate the distances of the x and the distance of the x

x = x1 - x2

x = (-1) - (-5)

x = 4

y = y1 - y2

y = 4 - 4

y = 0

This means that there is only distance in x, so the distance between the 2 points will be equal to 4

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
