You swim at 3 km/hr with your body perpendicular to a stream with a current of 5 km/hr. your actual velocity is the vector sum of the stream's velocity and ytour swimming velocity. find your actual velocity?

Step-by-step explanation:

You swim at 3 km/hr with your body perpendicular to a stream with a current of 5 km/hr.

If your actual velocity is the vector sum of the stream's velocity and your swimming velocity, it means that your actual velocity is the resultant velocity. Let R represent the resultant velocity. It means that

R² = 3² + 5² = 9 + 25

R² = 34

Taking square root of the left hand side and the right hand side of the equation, it becomes

R = √34 = 5.83 km/hr.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
