For each set of values, determine which is greater without using a calculator. √10 or √2 + √3
√10 is greater than √2 + √3 .
First we assume that √10 is greater than √2 + √3. Then we check if this relation is true.
So suppose that √10 > √2 + √3
On squaring both sides and using the algebraic identity [tex](a+b)^2=a^2+b^2+2ab[/tex],
⇒ 10 > 2 + 3 + 2√6
⇒ 10 > 5 + 2√6
Subtracting 5 from both sides, we get,
⇒ 5 > 2√6
Again squaring on both sides,
⇒ 25 > 4 x 6
⇒ 25 > 24
This is a true relation. So our assumption that √10 is greater than √2 + √3 was right.
Therefore, √10 > √2 + √3

What is a logarithmic function?
A logarithmic function in mathematics is defined as the function which is the inverse of the exponential function. It is denoted by using the word log. For example log 10 = 1
Expanding the given logarithm: log 2 x³y⁻²
Given logarithmic expression is log 2 x³y⁻²
Applying given properties of logarithmic function;
log a + log b = log (ab)
2 log a = log a^2
Now, log 2 x³y⁻² = log 3 + log x³ + log y⁻²
= log 3 + 3 log x - 2 log y

You have 150 pieces of fabric to make a quilt. Each piece of fabric is a square with a side length of 4 inches. You use as many pieces of fabric as possible to create a square quilt.
The most pieces of fabric that can be used is 144 pieces, making a quilt with 12 pieces on each side.
What is a square?The square is a term to refer to a geometric figure that is characterized by being a type of parallelogram with four sides of equal length. A square is a regular polygon that has all its sides equal, and its interior angles measure 90º.
How to calculate what is the maximum number of pieces I can use to make a square quilt?To identify the number of square pieces that I can use to make a square quilt, I must keep in mind that to create a square quilt I must put the same number of pieces on each side of the quilt so that it forms a perfect square.
To identify the maximum number of pieces needed, we can try taking the square root of 150, 149, 148, 147... until the result is a integer number (no decimals). In this case the first integer that appears is 12 by taking the square root of 144 as shown below.
[tex]\sqrt[2]{144} = 12[/tex]
This means that to make a square quilt we must use 144 pieces in total and place 12 pieces on each side of the square. Additionally we can state that the side length of this quilt is 48 inches because each piece measured 4 inches on a side.
4 inches × 12 = 48 inches.

If Upper pointing arrow with height of 11 and length of 9. Rectangular base of arrow has length of 7 and height of 8. All units are in centimeters. The area of the arrow by decomposing it into rectangles and triangles is: 69.5 square centimeters.
Total areaFirst step is to determine the Area of triangle using this formula
Area of triangle= ½×breadth ×height
Where:
Breadth=9
Height of triangle= 11 - 8
Height of triangle = 3cm
Area of triangle= ½ × 9 × 3
Area of triangle = 13.5 cm²
Second step is to determine the area of rectangle
Area of rectangle= length × breadth
Area of rectangle= 8 × 7
Area of rectangle= 56 cm²
Third step is to determine the total area
Total area=Area of triangles+ Area of rectangle
Total area = 13.5 + 56
Total area= 69.5 cm²
Therefore the area of the arrow by decomposing it into rectangles and triangles is: 69.5 square centimeters.

The measure of the z value from the given figure is 6 2/3.
We need to find the unknown value for the given figure.
What are trigonometric ratios?In trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent. These ratios are written as sin, cos, tan, sec, cosec(or csc), and cot in short. Trigonometric ratios can be used to determine the ratios of any two sides out of a total of three sides of a right-angled triangle in terms of the respective angles.
Using trigonometric ratios we can find the z value.
From the given figure, tan θ = 4/6 ----(I) and also tan θ = z/10 ----(II)
Now, equation (I) = (II)
⇒ 4/6 = z/10
⇒ 4 × 10 = z × 6
⇒ 6z = 40
⇒ z = 40/6
⇒ z = 20/3
⇒ z = 6 2/3
Therefore, the measure of the z value from the given figure is 6 2/3.

To divide a decimal number by a whole number, long divide as you would with two whole numbers, but put the decimal point in the answer at the same place it is at in the dividend. If it does not divide evenly, add a 0 to the end of the dividend and continue dividing until there is no remainder.
How do you divide decimals step by step?
The step-wise procedure for dividing decimals by a whole number is given below:
Step 1: Write the given division expression in the standard form.
Step 2: Now, we have to divide the decimal number's whole number part by the divisor.
Step 3: Place the decimal point in the quotient above the dividend's decimal point and then bring down the tenths' digit.
Step 4: If the tenth digit of the obtained dividend cannot be divided by the divisor, write 0 in the quotient and in front of the tenths' digit. Otherwise, proceed with the division process.
Step 5: Repeat the above step and keep adding the zeroes in the dividend until 0 is obtained in the remainder.

The range of f(x) = |x| is y ≥ 0. If a < 0 for g(x) = a|x|, what is the range of function g?
the range of the function g(x) will be y ≤ 0.
What is the range of g(x)?We know that the absolute value function g(x) can be written as:
g(x) = a*|x|
Remember that the range of f(x) = |x| is y > 0, and a is a negative number, so the function is reflected over the horizontal axis.
Then the maximum value will be when x = 0, then:
g(0) = a*|0| = 0, that is the maximum.
And then the function opens downwards. Then the range will be y ≤ 0.

b. 2 log₄6- log₄9
The single logarithm for the given expression (2 log₄6 - log₄9) is 1.
The given logarithmic expression is 2 log₄6 - log₄9.
Use the ability rule of the logarithm logₐ(Xⁿ) = n logₐ(X), to get 2
log₄6 - log₄9= log₄6² - log₄9
= log₄36 - log₄9 (Since 6² = 36)
Use the quotient rule of the logarithm logₐ(X/Y) = logₐ(X) - logₐ(Y), to get:
log₄36 - log₄9= log₄(36/9) = log₄(4)
(Dividing 36 by 9, to get, 36 ÷ 9 = 4)
= 1 (Since logₐ(a) = 1)
