If (x) = x / x^2-16 what is the value of f(-10)

Answers

Answer 1

Answer:

The value of the f(-10) is -5/42

We have given that,

$f (x) = x / x^2-16$

We have to determine the value of the f(-10)

We just replace the value of x by -10 therefore we get,

What is the function?

A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.

Therefore we get,

$f(-10)=(-10)/((-10)^2-16)$

$f(-10)=(-10)/(100-16) \nf(-10)=-(5)/(42)$

Therefore the value of the f(-10) is -5/42.

Answer 2

Answer:

Answer:

$f(-10)=-(5)/(42)$

Step-by-step explanation:

You just replace 'x' for the value given, -10.

$f(x)=(x)/(x^2-16)\n\n\nf(-10)=(-10)/((-10)^2-16)=(-10)/(100-16)=(-10)/(84)\n\n\n\n\nf(-10)=-(5)/(42)$

Kylee and her two of her friends are at a museum. they find two quarters and 1 dime on the ground, if Kylee and her friends share the money equally, how much will each person get?

Answers

20 cents; 2 quarters + 1 dime= 60 cents. Since theres three people, 60/3 = 20 cents. Each friend will get 20 cents. Hope this helps!

25+25+10=60
60 divided by 3 is 20
So each person gets $0.20

there are 148 juniors and 272 seniors attending prom this year. if there must be three chaperones per 60 students, how many chaperones are needed

Answers

21 chaperones are needed for 420 students.

Step-by-step explanation:

No. of juniors = 148

No. of seniors = 272

Total = 148+272 = 420 students

3 chaperones = 60 students

1 chaperone = $(60)/(3)=20\ students$

Ratio of chaperon to students = 1:20

Let,

x be the number of chaperons for 420 students.

Ration of chaperones to students = x:420

Using proportion

Ratio of chaperones to students :: Ratio of chaperons to students

$1:20::x:420$

Product of mean = Product of extreme

$20*x=420*1\n20x=420\n$

Dividing both sides by 20

$(20x)/(20)=(420)/(20)\nx=21$

21 chaperones are needed for 420 students.

Y – x² = 4.5 and y = x^4 Is this function linear or non linear?

Also show work and explain why.

Answers

Linear functions are in the form y=mx+b.

But the functions are in the form of y=x^4 and y-x^2=4.5.
Their exponents make them a quadratic function so it doesn't have the same rate of change. Therefore the equations are not linear. They are quadratic.

Linear functions are in the form of y = mx + b.

y - x² = 4.5 is not linear because of the x².

y = x⁴ is not linear because of x⁴.
