On his fishing trip Justin rides on hist 12 km south. The fish aren’t biting so he changes location and goes 4 km west. What is Justin's displacement?

Displacement= 12.65 km S 18.44°W

Step-by-step explanation:

Justin rides on hist 12 km south.

He changes location and goes 4 km west.

The displacement from his current location = X

X²= 12²+4²

X²= 144+16

X²= 160

X= √160

X= 4√10

X= 12.649 km

X= 12.65 km

His total distance covered=12+4

His total distance covered= 16 km

Tan ^-1 12/4= angle

71.56° = angle

90-71.56= 18.44°

Displacement= 12.65 km S 18.44°W

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
