Answer:

Infinitely many solution

Step-by-step explanation:

Simplify

2x - 4 = 2x - 4

Lets see:

if we put 1:

2 - 4 = 2 - 4

-2 = -2

Now lets try another number : 2

4 - 4 = 4 - 4

0 = 0

So we can say that there is more than one solution

this cancels out single solution and no solution

There are infinitely many solutions to the given algebraic expression 2x - 4 = 2(x - 2).

The algebraic expression is an expression that is composed of variables and their arithmetic operations.

From the given parameters

Open brackets

Since we are having the same algebraic expression on both sides;

Then, we won't be able to get exactly one solution but an infinite number of solutions.

This is because any number that is being substituted for the value of x will always give a different solution.

B. 1.16

Step-by-step explanation:

Correct!

The following expression [tex]log^6 8[/tex] evaluates to 0.86. So, The correct  answer is 0.86.

We can evaluate the expression log^6 8 as follows:

[tex]log^6 8 = log 8 / log 6 = 0.90309...[/tex] which rounds to 0.86 to two decimal places.

Therefore, the correct answer is D.

Logs:

The exponential function's inverse is known as the logarithm, or log. In other terms, a number's logarithm is the power that a different number, b, must be raised to in order to equal that number.

The expression log x = b represents a logarithm and is symbolized by the symbol "log". This implies that b is equivalent to x when raised to the power of log b.

For instance, since 2 raised to the power of 3 is 8, the logarithm of 8 to the base 2 is 3.

Calculus, statistics, computer science, and other branches of mathematics all make use of logarithms. Numerous more practical uses include determining pH levels and decibel levels.

Answer:

[tex](x + 14)^2 + (y + 3)^2 = 117[/tex]

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center [tex](x_0,y_0)[/tex] is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

In which r is the radius.

Center (-14, -3)

This means that [tex]x_0 = -14, y_0 = -3[/tex]

So

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

[tex](x - (-14))^2 + (y - (-3))^2 = r^2[/tex]

[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]

Passes through the point (-5,3),

This means that when [tex]x = -5, y = 3[/tex]. We use this to find the radius squared. So

[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]

[tex](-5 + 14)^2 + (3 + 3)^2 = r^2[/tex]

[tex]r^2 = 117[/tex]

So, the equation of the circle is:

[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]

[tex](x + 14)^2 + (y + 3)^2 = 117[/tex]

C. A pyramid has face, edges and vertices

First approach :

The above series can be seen as

1600 , (1600–400) 1200, (1200–300) 900 .

So we see that the values are getting decreased by 400,300 respectively.

Hence the next term in the sequence will be 900–200 = 700.

Other approach could be :

A geometric progression with ratio as 3/4.

1600*(3/4) = 1200

1200*(3/4) = 900

900*(3/4) = 675

Taking the above two approaches in mind,the two possible answers could be 700 or 675

Um- here ya go

The 20th term of the sequence.

1600, 1200, 900, ..., is 6.76.

A unique kind of sequence called a geometric sequence has a constant ratio between every two succeeding terms. This ratio is regarded as one of the geometric sequence's common ratios.

aₙ=a₁(r)ⁿ⁻¹

Given:

A geometric sequence,

1600, 1200, 900, ...

To find the common ratio:

take the ratio of successive terms

r = The value of the second term / the value of the first term

r = 1200/1600 = 0.75.

The explicit formula of a geometric sequence is,

aₙ=a₁(r)ⁿ⁻¹

aₙ= 1600(0.75)ⁿ⁻¹

a₂₀ = 1600(0.75)¹⁹

a₂₀ = 6.76

Therefore, the 20th term is 6.76.

Answer: 1196 cm³

Step-by-step explanation:

Volume of the rectangular prism: 12 x 20 x 5 = 1200 cm³

Volume of the eraser: 4 x 2 x 0.5 = 4 cm³

Therefore volume not occupied = Rectangular prism volume - eraser volume

1200 - 4 = 1196 cm³

Answer:

1196

Step-by-step explanation:

4 * 2 * 0.5 = 4

12 * 20 * 5 = 1200

1200 - 4 = 1196

Answer:

Step-by-step explanation:

volume = 34cm³

volume = 4/3×π×radius³

34cm³ = 4/3 × 3.14 × radius³

34cm³ = 12.56/3 × radius³

radius³ = 34×3/12.56

radius³ = 8

radius = ³√8

radius = 2cm

diameter = 2×radius
