Answer:

The Range is the set of all outputs for a function.

The Domain is the set of all inputs for a function.

Step-by-step explanation:

The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The domain of a function is the set of values that we are allowed to plug into our function. This set is the (x) values in a function such f(x)

Whatever values x takes are examples of domain input while the corresponding values of y for each value of x are examples of range output.

A Example would be f(x)=x+3

Answer:

The Range is the set of all outputs for a function
The Domain is the set of all inputs for a function

For example

f(x)=x+3

Here Domain and range both are set of all real numbers

kimberly is driving 1323 miles from wichita to charleston. She drives 443 miles the first day and 409 the second day. Round each

Elodia [21]

Answer:

1323 rounds to 1320

443 rounds to 440

409 rounds to 410

1320 - (440 + 410) =

1320 - 850 =

Rewrite the equation y=2|x−3|+5 as two linear functions f and g with restricted domains.

Mama L [17]

Answer:

f(x) = 2+5

g(x) = 2(-(x−3))+5

Step-by-step explanation:

If you remember, an absolute value can have two different answer, a positive and negative answer because the absolute value symbol makes all values in it positive. Example: |-2|=2 and |2|=2

So if y = 2|x−3|+5

then the two possibilities are

y = 2(x−3)+5 and

y = 2(-)+5

Set one of them equal to f(x) and the other one to g(x)

f(x) = 2(x−3)+5

g(x) = 2(-(x−3))+5

You can also write it as a piecewise function.

$y(x)=$\begin{array}{cc} \{ & \begin{array}{cc} -(x-3) & x3 \end{array}\end{array}$$

#10 using right angle below find the tangent of angle A.

just olya [345]

Answer: the first option is the correct answer.

Step-by-step explanation:

Triangle ABC is a right angle triangle.

From the given right angle triangle,

AB represents the hypotenuse of the right angle triangle.

With m∠A as the reference angle,

AC represents the adjacent side of the right angle triangle.

BC represents the opposite side of the right angle triangle.

To determine the tangent of angle A, we would apply the Tangent trigonometric ratio. It is expressed as

Tan θ, = opposite side/adjacent side. Therefore,

Tan A = 5/5√3 = 1/√3

Rationalizing the surd, it becomes

1/√3 × √3/√3

Tan A = √3/3

Working together, two secretaries can stuff the envelopes for a political fund-raising letter in 3 hours. Working alone, it take

AlekseyPX

Answer:

Faster worker takes 4 hours and slower worker takes 12 hours.

Step-by-step explanation:

Let x be the time ( in hours ) taken by faster worker,

So, according to the question,

Time taken by slower worker = (x+8) hours,

Thus, the one day work of faster worker = $\frac{1}{x}$

Also, the one day work of slower worker = $\frac{1}{x+8}$

So, the total one day work when they work together = $\frac{1}{x}+\frac{1}{x+8}$

Given,

They take 3 hours in working together,

So, their combined one day work = $\frac{1}{3}$

$\implies \frac{1}{x}+\frac{1}{x+8}=\frac{1}{3}$

$\frac{x+8+x}{x^2+8x}=\frac{1}{3}$ ( Adding fractions )

$3(2x+8)=x^2+8x$ ( Cross multiplication )

$6x+24=x^2+8x$ ( Distributive property )

$x^2+2x-24=0$ ( Subtraction property of equality )

By quadratic formula,

$x=\frac{-2\pm \sqrt{100}}{2}$

$x=\frac{-2\pm 10}{2}$

$\implies x=4\text{ or }x=-6$

Since, hours can not negative,

Hence, time taken by faster worker = x hours = 4 hours,

And, the time taken by slower worker = x + 8 = 12 hours.
