Daredevil Danny was cliff jumping. He jumped

off a cliff that was 14.2 meters above the

surface of the water. At the end of his jump,

Danny was 2.3 meters below the surface of the

water.

Step-by-step explanation:

Given:

Initial distance, Di = 14.2 m

Final distance, Df = 2.3 m

Distance fallen = Di + Df

= -14.2 + (-2.3)

= -16.5

-16.5 tells us the total distance danny had fallen and the direction of the fall that is, 16.5 m from the origin.

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
