Find the perimeter and the area of the polygon with the given vertices. W (11,2), X (11,8), Y (14,8), Z (14,2)
liberstina [14]

Answer:

The perimeter of the polygon = 18 units

The area of the polygon will be A=18 square units

Step-by-step explanation:

<u><em>Computing the Perimeter of the Polygon: </em></u>

Considering the polygon with vertices

  • W (11,2)
  • X (11,8)
  • Y (14,8)
  • Z (14,2)

As the polygon is drawn in coordinate plane as shown in figure a.

From the attached figure a, we can observe that

  • The length of the side WZ = 3 units
  • The length of the side ZY = 6 units
  • The length of the side WX = 6 units
  • The length of the side XY = 3 units

So, the perimeter of the polygon can be calculated by taking the sum of the lengths of all sides i.e.

The perimeter of the polygon = WZ + ZY + WX + XY

                                                  = 3 + 6 + 6 + 3

                                                  = 18 units

<u><em>Computing the Area of the Polygon: </em></u>

Area can be calculated by multiplying the length and width of the polygon.

A=lw

So, the area will be:

A=lw

A=(3)(6)

A=18

Therefore, the area of the polygon will be A=18 square units

If (x + 2 ) is a factor of x3 − 6x2 + kx + 10, k =
BartSMP [9]
If a binomial x-a is a factor of a polynomial p(x), then p(a)=0.

x+2 is a factor of p(x)=x³-6x²+kx+10, so p(-2)=0.

p(-2)=0 \\&#10;(-2)^3 - 6 \times (-2)^2 + k \times (-2) + 10=0 \\&#10;-8-6 \times 4-2k+10=0 \\&#10;-8-24-2k+10=0 \\&#10;-2k-22=0 \\&#10;-2k=22 \\&#10;k=\frac{22}{-2} \\&#10;\boxed{k=-11}

Given that f(–2.4) = -1 and f(-1.9) = -8, approximate<br> f'(-2.4).<br> f'(-2.4)
lora16 [44]

Answer:

f'(-2.4) ≈ -14

General Formulas and Concepts:
<u>Algebra I</u>

Coordinate Planes

  • Coordinates (x, y)

Slope Formula: \displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}

Functions

  • Function Notation

<u>Calculus</u>

Differentiation

  • Derivatives
  • Derivative Notation

Step-by-step explanation:

*Note:

The definition of a derivative is the slope of the <em>tangent</em> <em>line</em>.

<u>Step 1: Define</u>

<em>Identify.</em>

f(-2.4) = -1

f(-1.9) = -8

<u>Step 2: Differentiate</u>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>.

  1. [Derivative] Set up [Slope Formula]:                                                           \displaystyle f'(-2.4) \approx \frac{f(x_2) - f(x_1)}{x_2 - x_1}
  2. Substitute in coordinates:                                                                           \displaystyle f'(-2.4) \approx \frac{-8 - -1}{-1.9 - -2.4}
  3. Evaluate:                                                                                                       \displaystyle f'(-2.4) \approx -14
