Equations relating an independent variable to a dependent variable is a function. 

Simply put, the independent variable is the input variable, most often x. The dependent variable, or output variable, is the one for which the equation must be evaluated for a given x, is usually a y. In function notation, we swap out y for f(x).

Find the root that is a real number. rootindex 4 startroot 4096 endroot

Answers

the answer would be C.

Answer: 8

Step-by-step explanation:[tex]\sqrt[4]{4096}[/tex]

We need to factor this, so

[tex]4096|2\\2048|2\\1024|2\\512|2\\256|2\\128|2\\64|2\\32|2\\16|2\\8|2\\4|2\\2|2\\1[/tex]

When 75% of a number is added to 6, the result is 3 more than the number. find the number?

Answers

hello : 
let : x  this the number
(75/100)x +6  = x+3

(3/4)x - x = 3 -6
(-1/4)x = -3
x = 12

To find the number in question, an equation is set up and solved, resulting in the number 12, which satisfies the given conditions where 75% of the number added to 6 equals 3 more than the number itself.

The question asks to find a number such that when 75% of it is added to 6, the result is 3 more than the number itself. To find this number, we can set up an equation: Let the number be represented by x. So, we have 0.75x + 6 = x + 3. To solve for x, we subtract 0.75x from both sides of the equation to get 6 = 0.25x + 3. Next, we subtract 3 from both sides to get 3 = 0.25x. Finally, dividing both sides by 0.25 gives us x = 12. Therefore, the number we are looking for is 12

Daniel income tax rate is 15% if he made 32,000 this year what will his pay be in taxes this year

Answers

Final answer:

Daniel will pay $4,800 in taxes for the year by applying a 15% tax rate to his $32,000 income.

Explanation:

To calculate the amount of income tax Daniel will pay on his $32,000 income, we will apply the 15% tax rate that corresponds to the income bracket provided in the reference material. Here's how the calculation is done:

First, identify the total income: $32,000.Next, multiply the total income by the tax rate: $32,000 * 15% (or 0.15).The calculation will be: $32,000 * 0.15 = $4,800.

Therefore, Daniel will pay $4,800 in taxes for the year.

Which statement is true about the domain of y = 3(2^-x)? Explain.

The domain is all real numbers greater than or equal to 2.
The domain is all real numbers greater than 0
The domain is all real numbers
The domain is all real numbers less than 0

Answers

We want to determine the domain of [tex]{y=3 \cdot 2^{-x}=3 \cdot ({2^{-1}})^x=3 \cdot ({ \frac{1}{2}})^x[/tex]

any function of the form [tex]y=f(x)=a \cdot b^x[/tex] is called an "exponential function",
the only condition is that b is positive and different from 1, and a is a nonzero real number.

The domain of such functions is all real numbers.

That is for any x, the expression 3(2^-x) "makes sense".



Answer: The domain is all real numbers

The correct statement about the domain of y = 3(2-x) is that the domain is all real numbers. The domain of the function y = 3(2^-x) is all real numbers, as there are no restrictions on x from the form of the function itself.

The correct statement about the domain of y = 3(2-x) is that the domain is all real numbers. This is because for the function given, there are no restrictions on the values that x can take. The base of the exponent, 2, is positive and since exponents can take any real number, negative or positive, there is nothing to prevent any real x from being used as an input. Furthermore, since the function does not contain any terms that would result in undefined operations, such as division by zero or negative numbers under an even root, the domain remains unrestricted.

If a cube shaped cell is 3 units tall by 3 units wide and 3 units long, what is the volume of the cell?

Answers

it should be 6 because cubes have six sides

The volume of the cube is 27 cubic units.

Volume = side length × side length × side length

Given:

the side length of the cube is 3 units,

we can calculate the volume as follows:

Side length = 3 units

Volume = 3 units × 3 units × 3 units

              = 27 cubic units

So, the volume of the cube-shaped cell is 27 cubic units.

Given that (-4,5) is on the graph of f(x), find the corresponding point for the function f(2x)

Answers

Answer:

the correct answer is (-2,5)

Step-by-step explanation:

you multiply 1/2 by -4 to get the x value

To find the corresponding point on the function f(2x) given a point on the original function f(x), simply multiply the x-coordinate by 2. In this case, the corresponding point is (-8,5).

Given: Point (-4,5) is on the graph of f(x).

To find: Corresponding point for the function f(2x).

Solution:

When x = -4, 2x = 2*(-4) = -8.So, the corresponding point for f(2x) would be (-8,5).

From (1),

y=9x and
y=2x+63

subsitute 9x for y

9x=2x+63
minus 2x from both sides
9x-2x=2x-2x+63
7x+0=63
7x=63
divide both sides by 7
7x/7=63/7

Find the Perimeter of the polygon with the vertices X(-1,3), Y(3,0), and Z(-1,-2). Round the answer to the nearest hundredth

Answers

The perimeter is 14.47
 
Since you have 3 vertices, the polygon you have is a triangle. The sides of the triangle will be XY, XZ, and YZ. Just use the pythagorean theorem to calculate the length of each side and then add the lengths together for the result. Side XY = sqrt( (-1-3)^2 + (3-0)^2) = sqrt(16+9) = sqrt(25) = 5 Side XZ = sqrt ( (-1-(-1))^2 + (3-(-2))^2) = sqrt(0+25) = sqrt(25) = 5 Side YZ = sqrt( (3-(-1))^2 + (0-(-2))^2) = sqrt(16 + 4) = sqrt(20) = 4.47 Now add the length of each side together 5 + 5 + 4.47 = 14.47

In a recent year there were about 400,000,000 mobile internet users. That same year, there were about 1.2* into 10 ninths desktop internet users. About how many time larger was the number of desktop internet users than the number of mobile internet users?

Answers

Final answer:

The number of desktop internet users is 3 times larger than the number of mobile internet users.

Explanation:

To find out how many times larger the number of desktop internet users is compared to mobile internet users, we need to perform a division. We divide the number of desktop internet users by the number of mobile internet users.

The number of desktop internet users is represented as 1.2 x 109. To simplify this number, we can write it as 1,200,000,000. The number of mobile internet users is 400,000,000.

Now, we divide the number of desktop internet users by the number of mobile internet users:

1,200,000,000 / 400,000,000 = 3

Therefore, the number of desktop internet users is 3 times larger than the number of mobile internet users.
