Answer:

2log5(x) - 2log5(4)

Step-by-step explanation:

An expression is defined as a set of numbers, variables, and mathematical operations. The expression that is equivalent to log₅(x/4)² is 5log(x) - 5log(4).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given expression log₅(x/4)² can be expressed as,

log₅(x/4)²

= 5log(x/4)  {∵ log(aᵇ) = b log(a) }

=5[log(x) - log(4)]

= 5log(x) - 5log(4)

Hence, the expression that is equivalent to log₅(x/4)² is 5log(x) - 5log(4).

Answer:

Approximately 24 feet.

Step-by-step explanation:

Refer to the two diagrams attached (created with Geogebra.)

The wire between the speaker and the amplifier shall be routed along the wall. The length of the connection depends on the height of the point P at which the wire turns. Point P is shown in green in both diagrams.

To find the optimal position of that turning point, imagine that the two adjacent walls of the room are unfolded into two rectangles in the same plane (diagram 2.) Consider the claim: the shortest connection shall be a straight line that links the two devices when the two walls are unfolded. This explanation will show why this claim is true using the triangle inequality theorem.

Assume this claim is false: the connection will be even shorter if the wire turns at P', which is a point other than P. The length of the connection is now the sum of the two segments:

In contrast, if the wire is routed through point P, the length of the connection will simply be

Point P is on the line that connects the amplifier and the speaker in diagram 2. However, P' is a point other than P, meaning that P' is off the line between the speaker and the amplifier. It is thus possible for the following three points to form a triangle:

By the triangle inequality theorem, the sum of any two sides of a triangle is greater than the length of the third side. To make full use of this theorem, consider the length of the three sides in this triangle:

[tex]\left\{\begin{array}{ll}\left.\begin{aligned}&\text{distance between amplifier and P}'\text{.}\\&\text{distance between P}' \text{ and speaker.}\end{aligned}\right\}&\text{Length of the second connection}\\\text{distance between amplifier and speaker}\end{array}\right.[/tex].

The sum of the first two distances shall be greater than the third. In other words, the length of the connection through P' will be greater than the length of the connection through P. This fact contradicts the assumption that the original claim is false. In other words, the claim that P gives the shortest connection is true.

Find the length of the shortest connection using the Pythagorean Theorem. Refer to the second diagram, the connection is the hypotenuse of a right triangle with

The length of the connection (the hypotenuse) will be:

Answer:  2x³(x² + 5x - 11)

Step-by-step explanation:

2x⁵ + 10x⁴ - 22x³

Factor out the GCF (2x³)

2x³(x² + 5x - 11)

Since there are no values whose product is -11 and sum is +5, this cannot be factored further.

Answer:

x=7

Step-by-step explanation:

Solve for x:

3 x + x + 5 = 33

x + 3 x = 4 x:

4 x + 5 = 33

Subtract 5 from both sides:

4 x + (5 - 5) = 33 - 5

5 - 5 = 0:

4 x = 33 - 5

33 - 5 = 28:

4 x = 28

Divide both sides of 4 x = 28 by 4:

(4 x)/4 = 28/4

4/4 = 1:

x = 28/4

The gcd of 28 and 4 is 4, so 28/4 = (4×7)/(4×1) = 4/4×7 = 7:

Answer:  x = 7

The larger number is 26 and the smaller number is 7.

To determine the solution, take the following steps:

The given equation is  x + 3x + 5 = 33

Combine similar terms: x + 3x =33 - 5

Add similar terms: 4x = 28

Divide both sides by 4 : 7

The larger number = 33 - 7 = 26

Answer:

The correct option is B.

Step-by-step explanation:

The correct option is net.

A geometric net is a 2-dimensional shape that can be folded to form a 3-dimensional shape or a solid. Or you can say that  a net is a pattern made when the surface of a three-dimensional figure is laid out flat showing each face of the figure. A solid may have different nets.

The basic steps to determine whether a net forms a solid: are:

1. Make sure that the solid and the net have the same number of faces and that the shapes of the faces of the solid match the shapes of the corresponding faces in the net.  

2. Visualize how the net is to be folded to form the solid and make sure that all the sides are properly fit together.

Nets are helpful when we need to find the surface area of the solids....

Step-by-step explanation:

The polynomial x² + 6x - 8 ( from values in first row )

is being evaluated at x = - 5 thus the factor is (x + 5)

If (x + 5) is a factor the remainder = 0

Hence (x + 5) is not a factor since remainder = 12 ≠ 0

When the polynomial is evaluated at x = 5  it's value is 12

The remainder theorem states that f(h) = remainder, hence

f(- 5) = 12 ← remainder

Answer:

-6ab+a+1

Step-by-step explanation:

add or subtract like terms.

The difference between (-5ab+a+3) and (ab+2) is calculated by combining like terms and performing the subtraction, resulting in -6ab + a + 1.

To find the difference between the two expressions (-5ab+a+3) and (ab+2), we need to subtract the second expression from the first. Applying the distributive property of subtraction over addition (i.e., a - (b + c) = a - b - c), we get:

Putting it all together, the difference of the two expressions is -6ab + a + 1.

Step-by-step explanation:

The scale factor of the dilation is: 2.5.

The length of AB is: 6 units.

The scale factor of a dilation (reduction or enlargement) = dimension of new figure / corresponding dimension of original figure.

The scale factor of the image given = B'C'/BC

Scale factor = 9.5/3.8 = 2.5

The subject of your question involves algebra, which is a branch of mathematics. When the question asks for the 'quotient of the difference of 5 times x cubed and 4 and x', it is asking for an algebraic expression. This expression can be written as (5x³ - 4)/x. This expression cannot be simplified further as the terms in the numerator are not like terms.

Remember that the 'difference' refers to subtraction, 'quotient' refers to division, and 'times' refers to multiplication in algebra. Also, 'x cubed' means x is being raised to the power of 3.

Expand -2(5x+8), simplify, isolate x by moving terms, and solve to get x = -15/8.

To solve the equation -2(5x + 8) = 14 + 6x step by step, here's what was done:

Step 1: Expand the left side of the equation by distributing -2 across the terms inside the parentheses:

-2(5x + 8) = -2 * 5x - 2 * 8 = -10x - 16

So, the equation becomes: -10x - 16 = 14 + 6x

Step 2: Group like terms together. Subtract 6x from both sides to get all the x terms on one side of the equation:

-10x - 6x = 14 + 16

This simplifies to: -16x = 30

Step 3: Now, isolate the variable by dividing both sides by -16:

(-16x)/(-16) = 30/(-16)

This simplifies to: x = -30/16 or x = -15/8

So, the solution for x is x = -15/8.

The complete question is here:

-2(5x+8)=14+6x The equation was solved using the following steps Step 1: -10z-16=14+6z Step 2: -16x-16=14 Step 3: -16x=30 Step 4: z= 21/-16 Step 5: z=- 15/8 Complete the statements below with the process used to achieve steps 1-4 Stop 12 to 5x and 8. Step 26x Step 3 : 16. Step 4: 16.
