Which of the following is a square root of 3 (cosine (StartFraction 4 pi Over 9 EndFraction) + I sine (StartFraction 4 pi Over 9 EndFraction) )? a) StartRoot 3 EndRoot (cosine (StartFraction 4 pi Over 45 EndFraction) + I sine (StartFraction 4 pi Over 45 EndFraction) )

b) StartRoot 3 EndRoot (cosine (StartFraction pi Over 9 EndFraction) + I sine (StartFraction pi Over 9 EndFraction) )

c) StartRoot 3 EndRoot (cosine (StartFraction 49 pi Over 60 EndFraction) + I sine (StartFraction 49 pi Over 60 EndFraction) )

d) StartRoot 3 EndRoot (cosine (StartFraction 11 pi Over 9 EndFraction) + I sine (StartFraction 11 pi Over 9 EndFraction) )

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

"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).
