It’s decreasing 2 degrees per hour. It’s starting at 82 degrees. The first hour decreases to 80 degrees. It’s hard to explain but the slope is -2 degrees per hour.

The air quality index, or aqi, measures how polluted the air is in your city and assigns a number based on the quality of the ai

makkiz [27]

The number of days in which the air quality index exceed 100 in the year 1988 is 75 days. Then the correct option is B.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The air quality index (AQI) is given by the function.

$\rm n = 1.76t^2-13.32 +41$

Where n be the number of days the AQI exceeds 100 in a given year.

For $\rm t = -2$ , then we have

$\rm n = 1.76(-2)^2-13.32(-2) +41\\\\n = 7.04+26.64+41\\\\n = 74.68 \approx 75$

More about the function link is given below.

an object is launched upward from ground level and reaches a maximum height of h feet. The initial velocity v (in feet per secon

DIA [1.3K]

<span>So we want to rewrite the function v=8h^2 in terms of h so that it can represent the height of an object that is launched upward. So we take a square root: sqrt v= h*sqrt 8. Then we divide both sides of the equation with sqrt 8: h=(sqrt v)/sqrt 8=sqrt(v/8). So our function is: h=sqrt(v/8) or h=(1/2)*sqrt(v/2). </span>
