Dale and sharon mahnke have decided to fence off the garden plot behind their​ house, using their house as a​ "fence" along one

side of a garden. the length​ (which runs parallel to the​ house) is 66 feet less than twice the width. find the dimensions if 30 feet of fencing is used along the three sides requiring it.

The length l is given as:

l = 2 w – 6

where w is the width

 

We know that the fencing is 30 feet therefore the perimeter (excluding the side of the house) is:

P = l + 2 w = 30

2 w – 6 + 2 w = 30

4 w – 6 = 30

w = 9

 

So the length l is:

l = 2 (9) – 6

l = 12

 

<span>The dimensions are 12 ft x 9 ft</span>

Which equation results from applying the secant and tangent segment theorem to this figure? x(x 2) = (x 4) x(x 4) = (x 2) x(x 4)
fomenos

The equation which is results from applying the secant and tangent segment theorem to the provided figure is,

x(2x +4) = (x +2)^2

<h3>What is secant and tangent segment theorem?</h3>

The secant-tangent theorem tells the relation of the line segment made by a tangent and the secant lines with the connected circle.

According to this theorem, if the tangent and secant segments are drawn from an exterior point, then the square of this tangent segment is equal to the product of the secant segment and the line segment from that exterior point.

The image of the given problem is attached below. In the attached image, the tangent is given as,

T=x+2

The secant is shown in the image has the value,

S=x+x+4\\S=2x+4

Now according to the secant tangent theorem,

x(2x +4) = (x +2)^2

Hence, the equation which is results from applying the secant and tangent segment theorem to the provided figure is,

x(2x +4) = (x +2)^2

Find a formula for the given polynomial.
levacccp [35]

In this question, we have to identify the zeros of the polynomial, along with a point, and then we get that the formula for the polynomial is:

p(x) = -0.5(x^3 - x^2 + 6x)

------------------------

Equation of a polynomial, according to it's zeros:

Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.

------------------------

Identifying the zeros:

Given the graph, the zeros are the points where the graph crosses the x-axis. In this question, they are:

x_1 = -2, x_2 = 0, x_3 = 3

Thus

p(x) = a(x - x_{1})(x - x_{2})(x-x_3)

p(x) = a(x - (-2))(x - 0)(x-3)

p(x) = ax(x+2)(x-3)

p(x) = ax(x^2 - x + 6)

p(x) = a(x^3 - x^2 + 6x)

------------------------

Leading coefficient:

Passes through point (2,-8), that is, when x = 2, y = -8, which is used to find a. So

p(x) = a(x^3 - x^2 + 6x)

-8 = a(2^3 - 2^2 + 6*2)

16a = -8

a = -\frac{8}{16} = -0.5

------------------------

Considering the zeros and the leading coefficient, the formula is:

p(x) = -0.5(x^3 - x^2 + 6x)
