aliya0001 [1]

Answer:

$x\geq 29,000$ and $x\leq 41,000$

Step-by-step explanation:

Let x be the altitude of a commercial aircraft

=>The expression " A minimum altitude of 29,000 feet" is equal to

$x\geq 29,000$

All real numbers greater than or equal to 29,000 ft

=>The expression " A maximum altitude of 41,000 feet" is equal to $x\leq 41,000$

All real numbers less than or equal to 41,000 ft

therefore, The compound inequality is equal to

$x\geq 29,000$ and $x\leq 41,000$

All real numbers greater than or equal to 29,000 ft and less than or equal to 41,000 ft

The solution is the interval [29,000,41,000]

The height and weight of several adults were recorded:

Natalija [7]

Independent variable is the height and dependent variable is weight so you will have a quadratic such as weight = number•height^2 + number•height + number. All you need is to figure out first number and second number and third number (usually denoted by a,b,c) it will be a very tedious calculation by hand which deals with sum of the weight, sum of the weight squared, sum of weight•weight, number of weights, and sum of heights etc etc with the same pattern. It should be done by a calculator. At the end the Weight = a height^2 + b height + c (with a b c results displayed on the calculator) and then Answer = a*5.8^2 + b*5.8 + c
