Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

See Explanation Below

Step-by-step explanation:

Given

\((sin x - cos x)^2 = sec^2x - tan^2x - 2sinx.cos x.\)

Required

Prove

To start with; we open the bracket on the left hand side

\((sin x - cos x)^2 = (sin x - cos x)(sin x - cos x)\)

\((sin x - cos x)^2 = (sin x )(sin x - cos x)- (cos x)(sin x - cos x)\)

\((sin x - cos x)^2 = sin^2 x -sinx cos x - sin xcos x + cos^2 x\)

\((sin x - cos x)^2 = sin^2 x -2sinx cos x + cos^2 x\)

Reorder

\((sin x - cos x)^2 = sin^2 x + cos^2 x - 2sinx cos x\)

From trigonometry;

\(sin^2x + cos^2x = 1\)

So;

\((sin x - cos x)^2 = sin^2 x + cos^2 x - 2sinx cos x\)

becomes

\((sin x - cos x)^2 = 1 - 2sinx cos x\)

Also from trigonometry;

\(sec^2x - tan^2x = 1\)

So,  

\((sin x - cos x)^2 = 1 - 2sinx cos x\)

becomes

\((sin x - cos x)^2 = sec^2x - tan^2x - 2sinx cos x\)

Answer:

(-3/2, 1/2)

Step-by-step explanation:

Answer:

\({↪ \bold{answer}} \\ n(P{ \small{U}}Q) = n(P) + n(Q) - n(P{ \small{n}}Q) \\ n(P{ \small{n}}Q) = (20 + 30) - 40 \\ = 50 - 40 \\ { \boxed{ \green{n(P{ \small{n}}Q) = 10}}} \\ \\ { \small{ \underline{ \blue{⚜beckerjnr}}}}\)

n(P∩Q) = 10.

A set is a grouping of well-defined, separate things. The term "well-defined" refers to a certain characteristic that makes it clear whether or not the provided object belongs to the set. The word "distinct" denotes that each item in a collection must be unique. The general formula for sets is n(A∪B) = n(A) + n(B) - n(A⋂B).

Given the value of n(p)=20, n(Q)=30, and n (PUQ)=40, to find n(P∩Q). Let's put these values in the general formula of the set.

n(P∪Q) = n(P) + n(Q) - n(P⋂Q)

40 = 20 + 30 - n(P⋂Q)

n(P⋂Q) = 10

therefore the value of n(P⋂Q) is 10.

Answer:

See Below

Step-by-step explanation:

Lets look at our numbers:

The balloon is at 1000 feet.

The balloon drops at a constant speed of -4 1/2 per second.

How long will it take to get to 215ft, in seconds, s.

Lets see, if you were to subtract 1000-215, you will get 785.

The balloon needs to drop 785ft to get to 215ft above the ground.

The question asks how long will it take to get below 215ft.

Lets do the math for the descending feet. We calculated that it takes 785ft to hit 215ft above the ground, so, you need to divide 785ft by 4 1/2 to see how many seconds it takes. The answer for this is 174.4, we can make this 174 4/9.

**VERY IMPORTANT** If you use 174 4/9, this equals 215 seconds, it asks for below this, so you can use ANY number for this that it above this number.

Now for the inequality, look at the question, it asks how long will it take to get below, not equal to or more below, meaning that you can cancel out the inequality signs with lines below them. So your answer is 270 > ,
