Evaluate each logarithm.
log₄(256)
The value of log₄(256) is 4
In order to solve logarithm with different bases change of base rule is used, according to which a logarithm operation can be rewritten as a fraction of logarithms having a new base
logₐb = (logₓb) / (logₓa)
log₄(256) = (log₁₀256) / (log₁₀4)
= (log₁₀4⁴) / (log₁₀4)
As per the power rule of logarithms, the logarithm of an exponential number is equal to exponent times of the logarithm it means when an logarithmic term has an exponent it is transferred to the front of the logarithm and the logarithm is multiplied with it.
(∵ logₐMⁿ = n logₐM)
=(4log₁₀4) / (log₁₀4)
= 4
Hence, it is seen that the value of the above question, log₄256 is 4.

If you want to bisect a line segment, what would be the order of the following steps?
If you are aware of the line's length or have access to a ruler, bisecting (or cutting in half) a line is not difficult. However, you can still cut the line in half with a straightedge and compass even if you don't know how long it is.
Draw the section of the line you need to divide. You must use a straightedge to create the line segment if it is not already present. Put the compass needle on either terminal to accomplish this. Approximately half of the length should be covered by the compass when it is opened.
Using the compass, aim to keep the needle on the endpoint and refrain from changing the compass's setting. To do this, position your straightedge on the intersection of the arcs above the line and line them up with the intersection below the line. The line is bisected at a 90-degree angle by the line you draw connecting the two arc intersections.

in the polynomial $(ax^6 bx^8 cx^3 d)(x^5 ex^4 f)(x^2 gx h)$, letters $a$ through $h$ are all nonzero constants. what is the degree of the polynomial?
I assume you mean the polynomial
[tex](ax^6 + bx^8 + cx^3 + d) (x^5 + ex^4 + f) (x^2 + gx + h)[/tex]
The degree of this polynomial is the exponent of the largest power of [tex]x[/tex] in the expansion of the product.
This term is the product of the largest power terms in each factor. These are
[tex]ax^6 + bx^8 + cx^3 + d \implies bx^8[/tex]
[tex]x^5 + ex^4 + f \implies x^5[/tex]
[tex]x^2 + gx + h \implies x^2[/tex]
So, the largest power term in the polynomial is
[tex]bx^8 \cdot x^5 \cdot x^2 = bx^{15}[/tex]
and the degree is 15.

What is the value of each logarithm?
a. log₅125
The answer for the given logarithmic function is 3
Logarithm is a mathematical tool used to make high value calculations simple.
It is the exponent to the power of which a number must be raised to give a certain result.
Some of the important formulas in logarithm are:
loga[tex]b^{n}[/tex] where a is considered as base of the logarithm and b is the argument
is given as nlogab
when base and the argument is same , log is given as 1
logabc where a is the base is given as logab+logc
loga b/c where a is the base is given as logab-logac
Now it is given to us to find the value of log₅125
where 5 is the base and 125 is the argument
125 = 5x5x5 which is [tex]5^{3}[/tex]
hence 125 can be written as 5^3
Thus the logarithmic function becomes
log₅125=log₅[tex]5^{3}[/tex]
thus it can be written as3log₅5
Now we know that log₅5 can also be written as log5/log5
And hence log5/log5 becomes 1
Thus 3log₅5 = 3*1 =3
Hence the answer to the given logarithm is 3

Does anyone know how to solve 7 and 8?
The area and perimeter of the figures are 7) area=544 cm² and perimeter = 120 cm (8)area = 90cm² and perimeter = 46 cm .
Area is defined as the total surface occupied by a figure. The SI unit of area is m² .
Area of rectangle is given by the product of its two sides the length and Width
Perimeter is the sum of all sides of a two-dimensional figure.
7) In the first figure we have to separate it into a square and a rectangle.
Area of the square on top = 16 × 16 = 256 cm²
Length of the longest side in the second rectangle = 16 + 8+12=36cm
Area of the second rectangle = 36 × 8 = 288 cm²
Total area of the figure = (288 + 256) cm² = 544 cm²
Perimeter = 16 + 16 + 8 + 8 + 36 + 8 + 12 + 16 = 120 cm (taking all sides anti-clockwise from the top.)
8)Here we separate the two figures into two rectangles .
Length of the rectangle = 12 cm
Area of the first rectangle = 12 × 5 = 60 cm²
Area of the second rectangle = (6 × 5) cm² = 30cm²
Total area = (60 + 30)cm² = 90cm²
Perimeter = (5 + 6 + 7 + 5 + 12 + 11) cm² = 46 cm

The values of x and y that makes quadrilateral ABCD a parallelogram are x = 9 and y = 3
How to determine the values of x and y?The figure that completes the question is added as an attachment
The opposite sides of a parallelogram are congruent
This means that
5x - 20 = 7x - 38
4y + 11 = 6x - 31
So, we have
5x - 20 = 7x - 38
Collect the like terms
7x - 5x = 38 - 20
Evaluate the like terms
2x = 18
Divide through by 2
x = 9
Substitute x = 9 in 4y + 11 = 6x - 31
So, we have
4y + 11 = 6 x 9 - 31
Evaluate the product
So, we have
4y + 11 = 23
This gives
4y = 12
So, we have
y = 3
Hence, the values of x and y that makes quadrilateral ABCD a parallelogram are x = 9 and y = 3

What is a Rectangle?Rectangle is two - dimensional shape with four sides such that the pair of two opposite sides are equal and parallel to each other.
Given is the width of rectangular classroom which is 9 ft wide. Its length is five times its width. From this, we can write -
Width [W] = 9 ft
Length [L] = 5W = 5 x 9 = 45 ft
The perimeter of rectangle is the sum of the length of its sides. Therefore, the perimeter [P] of the rectangle will be -
[P] = 2(L + W) = 2(9 + 45) = 2 x 54 = 108 ft

Mayerlin wants to ride her bicycle 56 miles this week. She has already ridden 8 miles. If she rides for 6 more days, what is the average number of miles she would have to ride each day to meet her goal?
Answer:
If in the next 6 days she rides an average of 8 miles per day, she will meet her goal.
Step-by-step explanation:
What is the average number of miles she would have to ride each day to meet her goal?
We know that Mayerlin wants to ride her bicycle for 56 miles this week, and she already has ridden 8 miles, so the distance left is:
56mi - 8mi = 48mi
Now, to find the average distance that she needs to ride each day in order to meet her goal, we need to take the quotient between the distance left and the number days that she has left (6 days), then we will get:
D = 48mi/6 = 8mi
This means that if in the next 6 days she rides an average of 8 miles per day, she will meet her goal.
