Acosine function has a period of 5, a maximum value of 20, and a minimum value of 0. the function is not a reflection of its parent function over the x-axis. which function could be the function described?

See picture.

Step-by-step explanation:

A cosine function is a wave which starts up at its max value on the y-axis. Here the max is 20 so the cosine graph will start at 20 on the y-axis.

It descends into its valley settling at its lowest point the minimum value. Here it is 0.

The number of times it does this within a cycle is the coefficient of the variable inside the function. This results in the period or length of one cycle. The period is found by dividing 2π by that coefficient. Here the period is 5. So 2π/x = 5, x = 1.256 will be the coefficient. This means between 0 and 2π, it completes 1.256 cycles.

Look for a graph with maximum 20 on the y-axis and minimum 0 that cycles through about 1.256 between 0 and 6.28. See attached picture.

"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).

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
