The length of a rectangle is represented by the function L(x) = 2x. The width of that same rectangle is represented by the funct

ion W(x) = 8x2 − 4x + 1. Which of the following shows the area of the rectangle in terms of x?
(L + W)(x) = 8x2 − 2x + 1
(L + W)(x) = 8x2 − 6x + 1
(L ⋅ W)(x) = 16x3 − 4x + 1
(L ⋅ W)(x) = 16x3 − 8x2 + 2x

I believe the correct answer from the choices listed above is the last option. The area of the rectangle can be calculated by the expression given as <span>(L ⋅ W)(x) = 16x3 − 8x2 + 2x. We obtian this as follows:
</span>

Area = LW
Area = 2x (<span>8x^2 − 4x + 1)
Area = 16x^3 - 8x^2 + 2x</span>

Answer: Area = LW

Area = 2x (8x^2 − 4x + 1)

Area = 16x^3 - 8x^2 + 2x

This composite shape is a rectangle with a semicircle attached on one end. The diameter of the semicircle is 6 feet.
Ugo [173]

As we can see on the picture we have a rectangle and half of circle.

The areas for half circle and rectangle are:

A_{rectangle}=a\cdot b \\A_{halfcircle}=\frac{A_{circle}}{2}=\frac{\pi r^2}{2}

The area of the figure is the sum of the area of half circle and rectangle. Also the height of a rectangle (6ft) is a diameter of a half circle therefore the radius of half circle is 6ft ÷ 2 = 3ft.

Now we calculate the areas.

A_{rectangle}=10\cdot 6=\underline{60} \\A_{halfcircle}=\frac{3.14\cdot3^2}{2}=\underline{14.13} \\A_{total}=A_{rectangle}+A_{halfcircle} =60+14.13=\boxed{74.13\approx74}

The area of the figure is approximately 74ft squared.

Hope this helps.

Which value for x completes the conditional relative frequency table by column? 0.17 0.25 0.40 0.85
Alchen [17]

The value of x that completes the conditional relative frequency table by column is 0.85

<h3>How to determine the value of x?</h3>

From the complete question, we have the following column elements

0.15   x     1

Express a sum

0.15 + x = 1

Subtract 0.15 from both sides

x = 0.85

Hence, the value of x that completes the conditional relative frequency table by column is 0.85
