At 4:00 AM, the temperature is – 12 ·F. If the temperature drops 3 °F per hour, what will the temperature be at 6:00 AM?

Answer:

[tex]x\leq 4[/tex] or [tex]x\geq 4[/tex]

Step-by-step explanation:

We are given that

[tex]f(x)=(8-2x)^2[/tex]

We have to find the restricted domain of f which make the inverse of f.

Substitute x=4

[tex]f(4)=0[/tex]

One-to-one function:

The function is called one-to-one when  

[tex]f(x_1)=f(x_2)[/tex] for [tex]x_1=x_2[/tex]

The function is one-to-one when [tex]x\leq 4[/tex] or [tex]x\geq 4[/tex]

When the function is one-to-one then the function has inverse function.

If the function is not one-to-one  then function has no inverse .

Therefore, the restricted domain of f which make the inverse of f(x) a function is given by  

[tex]x\leq 4[/tex] or [tex]x\geq 4[/tex]

Answer:

Step-by-step explanation:

Given the expression

4/5 x - 1/10 = 3/10

We are to find the value of x

4/5 x = 3/10 + 1/10

4/5 x = 4/10

Cross multiply

4x * 10 = 5 * 4

40x = 20

x = 20/40

x = 1/2

The value of x is 1/2

Answer:

Its 1/2 :)

Answer:How to Write 0.17 or 17% as a Fraction?

Decimal Fraction Percentage

0.2 20/100 20%

0.19 19/100 19%

0.18 18/100 18%

0.17 17/100 17%

Step-by-step explanation:

The percentage value ( 17 % ) as a fraction is A = 17/100

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the percentage value be represented as A

Now , the value of A = 17 %

And , percent" means "per hundred".

So, 17% means 17 per hundred, or 17/100

Hence , the fraction is A = 17/100

Answer:

Ok so the answer is sqrt of 39 but think about

Step-by-step explanation:

sqrt81 is 9 which is a whole number it is rational

sqrt16 is 4 which again is a whole number and is rational

1.9 is rational because it can be written as a fraction or ratio

but sqrt39 is a repeating decimal that goes on forever it still is a real number not fitting into the imaginary category but not a ration number.
