an= 10n+90

a10= 190

Answer from: chey1603

$\displaystyle a_n=100+10(n-1)$

$\displaystyle a_{10}=190$

Step-by-step explanation:

We have the arithmetic sequence:

100, 110, 120, 130...

And we want to determine the equation for the nth term of the sequence.

The standard form for the nth term of an arithmetic sequence is given by the formula:

$\displaystyle a_n=a+d(n-1)$

Where a_n is the nth term, is the first term, and is our common difference.

From the sequence, we can see that the first term is 100.

Also, each term is +10 the previous term. Hence, our common difference $\displaystyle d$ is +10.

Therefore, our equation is:

$\displaystyle a_n=100+10(n-1)$

To find the 10th term, we can substitute 10 for n and evaluate. Hence:

$\displaystyle a_{10}=100+10(10-1)$

Evaluate:

$\displaystyle a_{10}=100+10(9)=100+90=190$

Therefore, the 10th term is 190.

Answer from: Quest

"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).
