In which interval is the radical function f of x is equal to the square root of the quantity x squared 2 times x minus 24 end quantity increasing?
We get that the function f (x) = √ x² - 2 x - 24 is increasing at the interval [6, ∞).
A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
We are given the function as:
f (x) = √ x² - 2 x - 24
From the graph, the function f (x) = √ x² - 2 x - 24 is increasing over the interval [6, ∞).
Therefore, we get that the function f (x) = √ x² - 2 x - 24 is increasing at the interval [6, ∞).

An angle measure of 134.26° is converted to DMS notation as what
Angle measurement of 134.26° becomes 134° 15' 36" in DMS notation.
What is DMS notation?The standard way to express fractional parts of a degree is in decimal form or in minutes and seconds. The units of a degree are a minute (') and a second (′′). For degrees, minutes, and seconds, this form is frequently referred to as the DMS Form. Use the decimal's whole number portion for the degrees.Divide the final decimal by 60 to get the number of minutes. Use the answer's whole number component as minutes.The new decimal that is left after multiplying by 60 is the seconds.So, an angle measure of 134.26° is converted to DMS notation as:
= 134° 15' 36"(Refer the image given below for calculation)
Therefore, the angle measurement of 134.26° becomes 134° 15' 36" in DMS notation.

x² - 12x - 220
After factorization, the factors are (x - 22) (x + 10).
What is factorization?In mathematics, factorization is the process of dividing a large number into smaller numbers that, when multiplied together, yield the original number. Factorization occurs when you divide a number into its factors or divisors. For example, the factorization of the number 12 could be 3 times 4. The Greatest common factor (GCF), the Grouping method, the difference in two squares, and the sum or difference in cubes are the four main types of factoring.So, x² - 12x - 220:
x² - 12x - 220x² - x( 22 - 10 ) - 220x² - 22x + 10x - 220x(x - 22) + 10(x - 22)Factors: (x - 22) (x + 10)Therefore, the factors are (x - 22) (x + 10).

A package of 6 pairs of insulated socks costs $ 47.94. What is the unit price of the pairs of socks?
The unit price of the pair of socks is $7.99
How to calculate the unit price ?
Unit price can be described as the price of one item. In this case scenario, we are looking for the unit price of a pair of socks.
The unit price can be calculated as follows
6 pair=47.94
1 pair = x
Cross multiply both sides
6x= 47.94
Divide both sides by the coefficient of x which is 6
6x/6= 47.94/6
x= 7.99
Hence the unit price is $7.99

The solution for the given inequality is -10 < y ≤ -2.
InequalityIt is an expression mathematical that represents a non-equal relationship between a number or another algebraic expression. Therefore, it is common the use following symbols: ≤ (less than or equal to), ≥ (greater than or equal to), < (less than), and > (greater than).
The solutions for inequalities can be given by: a graph in a number line or numbers.
The question gives:
17 ≤ -10y -3 ≤ 97
For solving this exercide, you should write the previous compound inequality as:
17 ≤ -10y -3 (1)
-10y -3 ≤ 97 (2)
For inequality 117 ≤ - 10y -3
10y ≤ -3 -17
10y ≤ -20
y ≤ -20/10
y ≤ -2
For inequality 2-10y -3 ≤ 97

The scientific notation to write the number -20,000 with a power of 10.
The scientific notation to write the number -20,000 with a power of 10 is -2 ×10⁴.
Given that
The number is -20,000To find
We have to find the scientific notation form of number -20,000So, according to the question
We have
The number = -20,000For finding the scientific notation form of given number, first we have to know about scientific notation with a power of 10.
Scientific notation with a power of 10
To write any number with the help of power of 10 in very easy way is telling Scientific notation with a power of 10 . Because in that universe there is a lots of smallest and largest number present, so we can't write every numbers in single page. To write that numbers in very easy way the scientists was create a way to write that numbers with the help of power of 10.
So, now we can convert that number in a form of Scientific notation.
n = -20,000
Now multiply [tex]\frac{10^4}{10^{4}}[/tex], we will get
n = -20,000 × [tex]\frac{10^4}{10^{4}}[/tex]
n = [tex]\frac{-20,000\times 10^4}{10000}[/tex]

The cost of purple dye has been increasing over the last few months, and Robyn uses this dye as part of her tie dye scarf business. She’s worried that it will continue to rise to the point where she no longer makes a profit on her scarf sales. She currently has a 20% profit margin ([price - unit costs]/price) and dye is currently 60% of unit costs. What is the lowest percentage increase in the cost of dye that would make Robyn’s scarves unprofitable?
The lowest percentage increase in the cost of dye that would make the scarves unprofitable is 42%
How to calculate the percentage?(Price- Unit Cost)/Price= 20% or 0.2
Price- Unit Cost= 0.2 Price
0.8 Price = Unit Cost
Let Unit Cost be x
Price = x/0.8= 1.25x
Dye is 60% of unit costs= 0.6x
Cost of remaining material= 1 - 0.6x = 0.4x
Unit Cost= Cost of Dye+ Cost of remaining material
So, in order to become unprofitable, Unit Cost must be 1.25x
Therefore
1.25x= Maximum cost of dye+ 0.4x
Maximum Cost of Dye = (1.25-0.4)x = 0.85x
Percentage change in cost of dye= {(0.85x-0.6x)/0.6x}*100= 41.66 or 42%
Therefore, theowest percentage increase in the cost of dye that would make the scarves unprofitable is 42%.

What is the slope intercept form of a line ?
The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.
1.
It is given that equation is : y = 2/5x - 3.
So , the slope here is 2/5 and a parallel line will have the same slope.
We know that the slope intercept form of a line is :
y = mx + c
Put , slope(m) = 2/5 in above equation.
Given , (1,-1) i.e., x = 1 and y = -1
Now we substitute these values to find value of c.
-1 = 2/5(1) + c
-1 = 2/5 + c
-1 - 2/5 = c
(-5 - 2)/5 = c
-7/5 = c
Putting m = 2/5 and c = -7/5 , we get :
So, the equation of parallel line is :
y = [tex]\frac{2}{5}[/tex] x - [tex]\frac{7}{5}[/tex]
2.
We know that the product of the slope of two perpendicular lines is -1.
Given that equation is : y = -2/5x - 4 i.e., slope = -2/5
So , slope of a line perpendicular to this line is -1/(-2/5) = 5/2
And this line passes through the point (-3,1).
Equation of a line that passes through a point (x1 , y1) and slope (m) is :
(y-y1) = m (x-x1)
Here ;
x1 = -3 , y1 = 1 and m = 5/2
So , the equation of perpendicular line will be :
(y - 1) = [tex]\frac{5}{2}[/tex] (x - (-3))
(y - 1) = [tex]\frac{5}{2}[/tex] (x + 3)
y - 1 = [tex]\frac{5}{2}[/tex] x + [tex]\frac{15}{2}[/tex]
y = [tex]\frac{5}{2}[/tex] x + [tex]\frac{15}{2}[/tex] + 1
y = [tex]\frac{5}{2}[/tex] x + [tex]\frac{13}{2}[/tex]
Therefore , the answers are :
1. The equation of line parallel to y = [tex]\frac{2}{5}[/tex] x - 3 will be y = [tex]\frac{2}{5}[/tex] x - [tex]\frac{7}{5}[/tex] .
2. The equation of line perpendicular to y = - [tex]\frac{2}{5}[/tex] x - 4 will be y = [tex]\frac{5}{2}[/tex] x + [tex]\frac{13}{2}[/tex] .

The height of a triangle is 4 ft less than the base x. The area is 126ft^2 find the dimensions of the triangle
The dimension of the triangle are base = 18 ft , height = 14 ft .
The area of a triangle is defined as the total area bounded by the three sides of a given triangle. It's basically equal to half the base multiplied by the height which is given by [tex]A=\frac{1}{2} \times b \times h[/tex] ..(1)It is given that height of a triangle is 4 ft less than the base x which can be represented as height = x - 4 ....(2) and base = x
Putting above values in equation (1) , we get
[tex]126=\frac{1}{2} \times(x-4)\times x\\252=x(x-4)\\252=x^2-4x\\x^2-4x-252=0[/tex]
On factorizing , we get
[tex]x^2-(18x-14x)-252=0\\(x^2-18x)+(14x-252)=0\\x(x-18)+14(x-18)=0\\(x+14)(x-18)=0[/tex]
On equating it with zero , we get
[tex]x+14=0\\x=-14[/tex]
as length cannot be in negative so , we will not consider this solution.
