The reflection of triangle WXY across the x axis gives the points W'(0, 1), X'(3, -3) and Y'(2, 1).
What is transformation?Transformation is the movement of a point from its initial location to a new location. Types of transformations are reflection, rotation, translation and dilation.
The reflection of a point across the x axis is given by the rule (x, y) ⇒ (x, -y). Triangle WXY have endpoints at X(3, 3), Y(2, -1) and W(0, -1).
The reflection of triangle WXY across the x axis gives the points W'(0, 1), X'(3, -3) and Y'(2, 1).

x² - 12x - 220
Answers
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).

An angle measure of 134.26° is converted to DMS notation as what
Answers
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.

The height of a triangle is 4 ft less than the base x. The area is 126ft^2 find the dimensions of the triangle
Answers
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.
[tex]x-18=0\\x=18[/tex]
Using equation (2)
Height will be = 18 - 4 = 14 ft.

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?
Answers
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%.
