Answer: A=28.26 units²

Step-by-step explanation:

<h3>The formula for the area of a circle is A=πr²</h3>

You find the radius of the circle by dividing 6 by 2

because diameter is twice the radius.

Then you plug in 3 as radius to the equation.

So the equation looks like this:

A=3.14×3²

Then solve the equation:

A=3.14×9

A=28.26 units²

Write a polynomial with the zeros equaling to -1,1,8
Andreyy89

Answer:x³-8x²-x+8

Step-by-step explanation:

x are equal to -1,1,8 respectively

to form the polynomials just simply use this method put (x-)to the given numbers that are zeros of the polynomials

(x-(-))(x-1)(x-8)

(x+1)(x-1)(x-8) →(x+1)(x-1) are diff. of two squares (x²-1)

(x²-1)(x-8)

x²(x-8)-1(x-8)

p(x)=x³-8x²-x+8

Mini staw<br> D:<br> R:<br> what is the domain and range
IgorC [24]

The entire range of independent variable values is the domain of a function.

After substituting the domain, the range of just a function is the entire set of all possible values for the dependent variable (often y).

What is domain and range?

  • The collection of all x-values that can cause the function to "work" and produce actual y-values is known as the domain.
  • The range is the set of y-values that are produced when all the conceivable x-values are substituted.

The entire range of independent variable values is the domain of a function.

Keep these things in mind when locating the domain:

  1. A fraction's denominator (bottom) cannot be 0.
  2. In this section, the integer following a square root symbol must be positive.

After substituting the domain, the range of just a function is the entire set of all possible values for the dependent variable (often y).

The variety of potential y-values makes up a function's range (minimum y-value to maximum y-value)

  1. To observe what happens, substitute several x-values into the expression for y.
  2. Be sure to search for the least and highest y values.

horrorfan [7]

Answer:

The answer is "0.0764"

Step-by-step explanation:

Please find the complete question in the attached file.

\to \mu = \$ \ 4064\\\\\to \sigma = \$ \ 460 \\\\\to \sigma \bar{x} = \frac{\sigma}{\sqrt{n}}\\\\

        = \frac{460}{\sqrt{21}}\\\\ = \frac{460}{4.58257569}\\\\=100.3802

\to P(\bar{x}< \$ \ 3920) = \frac{P((\bar{x} - \mu \bar{x})}{\frac{\sigma \bar{x}

\to P(z < -1.43) = 0.0764 \\\\\to P(\bar{x}< \$ \ 3920) = 0.0764\\\\
