what is the direction of the boat's resultant velocity? round your answer to the nearest whole degree.
º north of east

The magnitude of the boat's resultant velocity is 31.0 m/s

The direction of the boat's resultant velocity is 23.0° north of east

Explanation:

A boat travels at 15 m/s in a direction 45° east of north

The vector of velocity is 15 m/s in direction 45° with north

The horizontal component = 15(m/s) sin(45)° = 10.61 m/s

The vertical component = 15(m/s) cos(45)° = 10.61 m/s

The boat then turns and travels at 18 m/s in a direction 5°  north of east

The vector of velocity is 18 m/s in direction 5° with east

The horizontal component = 18(m/s) cos(5)° = 17.93 m/s

The vertical component = 18(m/s) sin(5)° = 1.57 m/s

The horizontal component of the resultant velocity x is

x = 10.61 + 17.93 = 28.54 m/s

The vertical component of the resultant velocity y is

y = 10.61 + 1.57 = 12.18 m/s

The magnitude of the resultant velocity

R ≅ 31.0 m/s

The direction of the resultant velocity is north of east

The direction of the resultant velocity is

α = 23.0° north of east

The magnitude of the boat's resultant velocity is 31.0 m/s

The direction of the boat's resultant velocity is 23.0° north of east

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
