Answer:

≈ 35 ft²

Step-by-step explanation:

The area (A) of a regular pentagon is

A = \frac{1}{2} × perimeter × apothem

perimeter = 5 × 4.5 = 22.5 ft, thus

A = 0.5 × 22.5 × 3.1 = 34.875 ≈ 35 ft²

The mapping diagram shows a functional relationship
Gre4nikov [31]

Answer:

f(4)=\frac{1}{2}

f(x) = 4 when x is 8

Step-by-step explanation:

Domain is the set of x values that make the function defined. Allowed x values for the function (mapping).

The Range is the set of y values that make the function defined. Allowed y values for the function (mapping).

  • Whenever we need to find f(a), suppose, then we look for "a" in the domain and see its corresponding value mapping in the range.
  • Whenever we will be given a value for f(x) = a, suppose, and we have to find "x", we look at the value a in the range and find corresponding x value in the domain.

Firstly, we need f(4), so we look for "4" in domain and see which number it corresponds to in range.

That is \frac{1}{2}

Thus,

f(4)=\frac{1}{2}

Next,

We want "x" value that gives us a "y" value of 4. We look for "4" in the range and see which value it corresponds to. That is "8". So,

f(8) = 4

Plot the zeros of this function:<br><br> f(x) = (x – 1)(x – 7).
vredina [299]

Answer:

\boxed{\mathrm{view \: attachment}}

Step-by-step explanation:

The zeros of a function is where the function crosses the x-axis. The x-intercepts are the zeros of a function.

f(x) = (x - 1)(x - 7)

Let output equal to 0.

0 = (x - 1)(x - 7)

Set factors equal to 0.

x-1=0\\x=1

x-7=0\\x=7

The zeros of the function are x=1 and x=7.

The vertex of this parabola is at (-1,-3) which of the following could be its equation
Gnesinka [82]
Since these are parabolas with y being squared, the standard form of such a parabola with vertex at (h, k) is 

<span>x = a(y - k)^2 + h </span>

<span>There are no steps. Just look at what is inside the parentheses and compare it to (y - k) with k = -3. </span>
<span>Then look at what is added and compare it to h = -1. </span>

<span>For instance, A has (y + 1) in parentheses. So k = -1. And it has -3 added, so h = -3. That would be a vertex at (-3, -1).</span>
