Find the surface area of the composite solid. Round your answer to the nearest hundredth.

iogann1982 [59]

The surface area of the composite solid is 579.84 square feet

<h3>How to determine the surface area of the solid?</h3>

The composite solid that completes the question is added as an attachment

From the attached figure, we have the following figures:

Rectangular prism
Cylinder

The surface area of a rectangular prism is

A = 2(lw + lh + wh)

Using the dimensions of the prism, we have:

A = 2(6 * 11 + 6 * 8 + 8 * 11)

This gives

A = 404

The surface area of a cylinder is

A = 2πr^2 + 2πrh

Using the dimensions of the cylinder, we have:

A = 2 * 3.14 * 4^2 + 2 * 3.14 * 4 * 5

Evaluate

A = 226.08

The area of the circle between both shapes is

A = πr^2

This gives

A = 3.14 * 4^2

A = 50.24

The surface area of the composite solid is then calculated as:

Surface area = Area of rectangular prism + Area of cylinder - Area of circle

This gives

Surface area = 404 + 226.08 - 50.24

Evaluate

Surface area = 579.84

Hence, the surface area of the composite solid is 579.84 square feet

Find at least three different sequences beginning with the terms 3, 5, 7 whose terms are generated by a simple for- mula or rule

pychu [463]

1. Perhaps the simplest rule is one that makes this the start of an arithmetic sequence:

$a_{n+1}=a_{n}+2$

Then the sequence will continue ...

... 3, 5, 7, 9, 11, 13, 15, ...

2. We can multiply the two terms by some values, add the results, then add some constant. There are an infinite number of ways to choose such values. Here's one set of numbers that give the third term from the first two:

$a_{n+2}=4a_n-a_{n+1}$

Then the sequence will continue ...

... 3, 5, 7, 13, 15, 37, 23, ...

3. We can multiply adjacent values and add a constant.

$a_{n+2}=a_{n+1}\cdot a_n-8$

Then the sequence will continue ...

... 3, 5, 7, 28, 188, 5256, 988120, ...

(3xy/3x^2-12)*(x^2+3x+2/xy+y)

TiliK225 [7]

Value of expression $(3xy/3x^2-12)*(x^2+3x+2/xy+y)$ is $\frac{x}{x-2}$ .

<u>Step-by-step explanation:</u>

Here we need to evaluate expression : (3xy/3x^2-12)*(x^2+3x+2/xy+y) or ,

$(3xy/3x^2-12)*(x^2+3x+2/xy+y)$

Let's simplify this

⇒ $(\frac{3xy}{3x^2-12})(\frac{x^2+3x+2}{xy+y})$

Factorizing the terms we get:

⇒ $(\frac{3xy}{3(x^2-4)})(\frac{x^2+2x+x+2}{y(x+1)})$ { $a^2-b^2=(a+b)(a-b)$ }

⇒ $(\frac{xy}{(x-2)(x+2)})(\frac{x(x+2)+1(x+2)}{y(x+1)})$

⇒ $(\frac{xy}{(x-2)(x+2)})(\frac{(x+1)(x+2)}{y(x+1)})$

Cancelling similar terms we get:

⇒ $\frac{x}{x-2}$

Therefore , Value of expression $(3xy/3x^2-12)*(x^2+3x+2/xy+y)$ is $\frac{x}{x-2}$ .

A steel ball is traveling through water with a speed of x meters per second, where x is positive the drag force, F

frozen [14]

Answer:

0.032

Step-by-step explanation:

The drag force is described as the force experienced by an object due to movement through a liquid. In this case it is water. The equation used for drag force F is:

$F=0.5pu^2$

the density of water is p=1000 kg/m³. We know that F=0.5 N.

$0.5=0.5\cdot{1000}u^2$

$u=\sqrt{0.001}$

$u=0.031$

The speed is 0.032 m/s
