Aboat’s velocity measured in meter per second, is described by vector b=< 3,-4> . in two or more complete sentences explain how to find the speed of the boat and the direction it is traveling in standard position. in your final answer, include all of your calculations.

The term speed is used to denote distance  traveled divided by time. The speed is the magnitude of instantaneous  velocity and so can never be negative. In this problem, we have a boat’s velocity measured in meter per second, described by vector:

1. Therefore, the magnitude of this vector, which is also the speed of the boat can be found as:

2. On the other hand, the direction the boat is traveling is the angle that this vector makes with the horizontal. So this can be found as:

The representation of this problem is shown below.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
