A100-gallon fish tank fills at a rate of x gallons per minute. the function is f(x)=100/x. if the tank has been filling for 20 minutes, the total time to fill the tank is represented by the function f(x)=100/x+20. which graph represents this

D is correct graph.

Step-by-step explanation:

A 100-gallon fish tank fills at a rate of x gallons per minute.

If the tank has filling for 20 minutes, The total time to fill the tank is represented by the function,

It is rational function. We need to draw the graph of this function.

First we find vertical asymptote.

For VA: x+20=0

    x=-20

For x-intercept, Put f(x)=0

No x-intercept

For y-intercept, Put x=0

y-intercept: (0,5)

For HA,

y=0

Please see the attachment for graph.

Hence, D is correct graph.

"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:

the option best identifies the textual evidence that supports this conclusion is c.) when an argument is over, how many weighty reasons does a man recollect which his heat and violence made him utterly forget? in order to recognize textual evidence is to identify the topic sentence where the author states the main idea. textual evidence is what supports the topic sentence or main idea of a passage.
