Answer:

Step-by-step explanation:

When we apply the exponent rule: [tex](\sqrt[n]{x})^n = x[/tex]

[tex](\sqrt[3]{9})^2 * (\sqrt{20})^2 = 30(\sqrt[3]{9})^2[/tex]

[tex]= \mathrm{Decimal:\quad }\:129.80246\dots[/tex]

ln (e) = 1, by the properties of logarithm.

Now,

As seen by the definition of logarithms, [tex]log_b(a)=x[/tex]

In case of natural logarithm, b = e, i.e., [tex]log_e(a)=x[/tex] = ln (a) = x

In the given expression, a = e

Hence, ln (e) = x

By properties of logarithms, we get that: ln (e) = 1.

Hence, ln (e) = 1, by the properties of logarithm.

Answer:

3x^3 -8*x^2 + 8*x + 3

Step-by-step explanation:

The standard form for a plolynomial is:

a*x^n + b*x^(n-1) + c*x^(n - 2) ........

We have:

(x-1)(3x^2-5x-3)

this is equal to:

3*x^3 - 5*x^2 + 3*x - 3*x^2 +5*x + 3

where the thing that i did is distribute the multiplication

this is equal to:

3x^3 -8*x^2 + 8*x + 3

The value given expression of (x⁵ + 8)/(x + 1) is (x⁶ + 8x).

The given expression is-

(x⁵ + 8)/(x + 1)  .......equation 1

It is stated that;

x² + x = 1

Taking x common;

x(x + 1) = 1

Bring x on the other side.

(x + 1) = 1/x

Put the value of (x  + 1) in equation 1.

= (x⁵ + 8)/(x + 1)

= (x⁵ + 8)/[1/x]

Simplifying;

= (x⁵ + 8)x

Multiplying x on both values;

= x⁵x + 8x

= x⁶ + 8x

Thus, the value of the given expression is (x⁶ + 8x).

The common difference for the recursive equation [tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 5  is 5.

It is a sequence where the difference between each consecutive term is the same.

We have,

The recursive equation:

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 5

and [tex]a_{1}[/tex] = -3

We can find the consecutive term using the recursive equation.

[tex]a_{2}[/tex] = [tex]a_{1}[/tex] + 5 = -3 + 5 = 2

[tex]a_{3} =a_{2}[/tex] + 5 = 2 + 5 = 7

The sequence we get is:

The common difference means the differences in between two consecutive terms.

2 - (-3) = 5

7 - 2 = 5

12 - 7 = 5

Thus the common difference is 5.

The required value of sports imports of the United States in 2012 is $2,745,240,000,000.

.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

the total value of exports from the United States in 2012 = $2,210,585,000,000

Now it is also given that,

the total value of exports from the United States in 2012 = $837,965,000,000 more than half of the US imports

Therefore, we can write

the total value of exports from the United States in 2012 = $837,965,000,000 + imports/2

Putting the value of exports we get,

2,210,585,000,000 = 837,965,000,000 + imports/2

Taking alike terms together we get,

Imports/ 2 = 2,210,585,000,000 - 837,965,000,000

Solving we get,

Imports/ 2 = 1,372,620,000,000

Multiplying by 2 both the side by 2 we get,

Imports = 2,745,240,000,000

Thus, the value of imports of the United States in 2012 = $2,745,240,000,000

Thus, the required value of imports of the United States in 2012 is $2,745,240,000,000.

Step-by-step explanation:

(0,2) is the y-intercept

The area of a new circle that has line segment GX as its diameter is 121 pi cm² .

Suppose that,

The radius of the small circle (GH) = 10 cm.

The radius of the big circle (HX) = 12 cm.

We will add the line GH and HX to get the total length of line segment GX.

So, GX = GH + HX

            = 10 + 12

      GX = 22 cm.

So, the diameter of new circle will be equal to line segment GX as it is given in the question.

Then, the area of new circle  = π r²    ( r = radius)

 Radius = D/2 = 22/2      (D = Diameter)

           r = 11

Now,     Area = π × 11²

                     = 121π cm²

The string can be cut into 50 pieces of 10 cm length.

Length is a measurement of how long an object is or the distance between two points. Length is the term used to identify the size of an object or the distance from one point to another. It can be used to determine an object's size or the distance between two points.

A measurement of length is the distance between two locations or the length of an item. The term "length" is used to describe an object's size or the separation between two points. It may be used to calculate the size of an item or the separation between two places. Distance is measured in length. Length has the dimension of distance in the International System of Quantities. The majority of measuring systems choose a base unit for length from which all other units are derived.

Centimeters, meters, kilometers, inches, feet, and yards are some examples of conventional units used to measure length.

The solution for the radical equation √(x+3) = 4√x-2 is 7 / 3.

The phrase "algebraic expression" refers to any arrangement of terms that have undergone operations like addition, subtraction, multiplication, division, etc. (or variable expression).. Let's use the equation 5x + 7 as an example. Thus, 5x + 7 is an illustration of an algebraic expression.

Eliminate the radical on the both sides by squaring on both sides- 

Both sides must be raised to the second power.

√(x+3) ²=(4√x-2 )²

After squaring we get

x+3=16(x-2)

Solving the equation-

We get rearranged equation as :

x+3=16x-32

15x=35 x=35/15 which further reduces to 7/3 .

Check if the  solution is correct by putting it in original equation-

putting x=7/3 in the equation √(x+3) = 4√x-2 

we get √16/3=√16/3

Since their dot product is zero, then (6,-3) and (2,4) are normal to each other.

Step-by-step explanation:

Two vectors are said to be normal or perpendicular to each other if the result of their dot product is equal to zero.

These two vectors are also called orthogonal to each other.

Let u = (u₁, u₂) and  v = (v₁, v₂), then the dot product u . v is defined as:

u . v = u₁v₁ + u₂v₂

To check whether the vectors are normal to each other, let us check their dot product.

The given vectors are: (6,-3) and (2,4).

Let u = (6, -3) and  v = (2, 4), then,

u . v = 6 . 2 + (-3) . 4
