x^-9 - 6x^3 + 6 = 0

### Answers

The **solutions** of the **original** **equation** are x = -1.5, 1.5, 1/√[3].

To **solve** this equation, we can factor the l**eft-hand side** as follows:

x^-9 - 6x^3 + 6 = (x^-3 - 2)(x^6 + 3x^3 + 3) = 0

We can then **solve** for the **roots** of the equation by **setting** **each** **factor** **equal** to **zero**:

x^-3 - 2 = 0 -> x^-3 = 2 -> x = 2^(-1/3) = 1/√[3]

x^6 + 3x^3 + 3 = 0 -> x^6 + 3x^3 = -3 -> (x^3)^2 + 3(x^3) = -3 -> x^3 = (-3 ± √[9 - 4])/2 = -1.5, 1.5

The table shows the difference between the actual volumes of some bottled teas and the average volume of a bottled tea. Piyush opens a bottle of tea and finds that it has 0.75 ounce more than the average tea volume. Between what two bottles is the volume of the bottle that Piyush opened?

### Answers

By using **fractions** and **decimals**, it can be calculated that

Between bottle 2 and bottle 4 is the** volume** of the bottle that Piyush opened

**What is fraction and decimal?**

Suppose there is a **collection **and a part of **collection** has to be taken. The** part** which is taken is called **fraction**. In other words, **part **of a **whole **is called **fraction**.

The upper part of the** fraction** is the **numerator **and the lower part of the **fraction **is the **denominator.**

This is a word problem of **fraction **and **decimal**

For bottle 1

Difference between the **actual volumes** and the** average volume** = [tex]\frac{9}{10}[/tex] = 0.9 oz

For bottle 2

Difference between the **actual volumes **and the** average volume** = -1.1 oz

For bottle 3

Difference between the **actual volumes** and the** average volume** = [tex]1\frac{1}{4}[/tex] = 1.25 oz

For bottle 4

Difference between the **actual volumes** of some bottled teas and the **average volume** = -0.4 oz

Now 0.75 oz lies between -0.4 and 0.9

Between bottle 2 and bottle 4 is the **volume** of the bottle that Piyush opened

Use a double integral to find the area of the region. One loop of the rose r = 8 cos(3theta) Incorrect: Your answer is incorrect.

### Answers

The sum of the **areas** of the enclosed regions is 2.004 , and -3.811 the **rate** at which h changes with respect to x when x = 1.8 .

Given : f(x) = 1 + x + e^x^2 - 2x and g(x) = x^4 - 6.5x^2 + 6x + 2

The graphs of y = f(x) and y = g(x) intersect in the first **quadrant** at the points (0, 2), (2, 4), and (A, B) = (1.032832, 2.401108).

(a) the sum of the **areas** of the enclosed regions is given by

Area =

[tex]\int\limits^A_0[[g(x) - f (x)] dx +\int\limits^2_A [f(x) - g(x)] dx[/tex]

= 0.997427 +1.006919

= 2.004

(b) the sum of the **volumes** of the **enclosed regions** is given by

Volume = [[ƒ(x) − g(x)]² dx = 1.283

(c) the **rate** at which h changes with respect to x when x = 1.8

h(x) = f(x) = g(x)

h'(x) = f'(x) - g'(x)

h'(1.8) = f'(1.8) g'(1.8)

=-3.812 (or -3.811)

Hence , the sum of the **areas** of the enclosed regions is 2.004 , and -3.811 the **rate** at which h changes with respect to x when x = 1.8 .

b 366

c. 37

d. 316

### Answers

The answer to the nearest **whole percent** is:

366% of 44 = 161 (option b)

**Percent **means per a **hundred**. Percent is equal to a** fraction** of a hundred.

For example, 60% = 60/100.

To convert a fraction into a percent form, find its equivalent fraction with denominator 100.

Example:

3/4 is **equivalent** to 75/100. Hence,

3/4 = 75/100 = 75%

To multiply a percent with a whole number, convert the percent into its equivalent fraction.

In the given problem:

__% of 44 = 161

[tex]\frac{...}{100}\times44=161[/tex]

Let assign the unknown to a variable p

(p/100) x 44 = 161

p = 161 x 100 / 44

p = 365.9 ≈ 366

3/5(x - 7/10) = -3 1/4 enter answer as mixed number in simplest form

### Answers

**Answer:**

x=-4 43/60

**Step-by-step explanation:**

3/5(x - 7/10) = -3 1/4

3/5(x - 7/10) = -(3 1/4)

3/5(x - 7/10) = -(3 + 1/4)

3/5(x - 7/10) = -(12/4 + 1/4)

3/5(x - 7/10) = -13/4

3x/5 - (3/5)*(7/10) = -13/4

3x/5 - (3*7)/(5*10) = -13/4

3x/5 - 21/50 = -13/4

30x/50 - 21/50 = -13/4

(30x-21)/50 = -13/4

50*(30x-21)/50 = 50*(-13/4)

30x-21=-650/4

30x-21+21=21-650/4

30x=21*4/4 - 650/4

30x=84/4 - 650/4

4*(30x=84/4 - 650/4)

120x=84-650

120x=-566

x=-566/120

x=(-566/2)/(120/2)

x=-283/60

x=-(43+240)/60

x=-43/60 - 240/60

x=-4 - 43/60

x=-(4 + 43)/60

**x=-4 43/60**

X= -4 43/60 have a good day
