Given the coordinate, perform the following transformation and give the new coordinates.
12. Reflect (2, 3) over the x axis: (
13. Reflect (7, -2) over the y axis: (
14. Rotate (4, 5) 90° about the origin: (
15. Rotate (-3, -2) 270° about the origin:
16. Reflect (17, -23) over the line y=x.
12) (2, 3) over the x - axis becomes, (2, -3).
13) (7, -2) over the y - axis becomes, (-7, -2).
14) (4, 5) 90° about the origin becomes, (-5, 4).
15) (-3, -2) 270° about the origin becomes, (-2, 3).
16) (17, -23) over the line y = x becomes, (-23, 17).
What is transformation of points?
The reflection is the type of alteration that takes place when each point in the shape is reflected over a line. The picture is on the opposite side of the line from the pre-image when the points are reflected across a line, but it is still at the same distance from the line as the pre-image. The reflection of each point (p, q) onto an image point (q, p).
12) Reflect (2, 3) over the x axis:
Since, the x-coordinate of a point that is reflected across the x-axis stays constant, but the y-coordinate is assumed to be the additive inverse.
The x-axis' reflection of point (x, y) is (x, -y).
So, (2, 3) becomes, (2, -3).
13) Reflect (7, -2) over the y axis:
Since, the y-coordinate of a point that is reflected across the y-axis stays constant, but the x-coordinate is assumed to be the additive inverse.
So, (7, -2) becomes, (-7, -2).
14) Rotate (4, 5) 90° about the origin:
(x, y) → (-y, x) is the formula for a 90° rotation about the origin.
So, (4, 5) becomes, (-5, 4).
15) Rotate (-3, -2) 270° about the origin:
(x, y) → (y, -x) is the formula for a 270° rotation of the origin.
So, (-3, -2) becomes, (-2, 3).
16) Reflect (17, -23) over the line y=x.
The angle at which the point (x, y) is reflected across the line y = x is (y, x).
So, (17, -23) becomes, (-23, 17).

Susie is visiting the U.S. from Mexico. One day she stopped by a market and found a stall selling tomatoes for 0.83 dollars per pound. If 1 peso was worth 0.053 dollars that day, how much did the tomatoes cost in pesos per kilogram?
First fill in the two blanks on the left side of the equation using two of the ratios. Then write your answer rounded to the nearest hundredth on the right side of the equation.
The value of given ratio is 34.45 peso/kg as the given ratio are : 1 peso/0.053 dollar, 0.053 dollar/1 peso, 1 kg/2.2 lbs, 2.2 lbs/1 kg, 0.83 dollar/1lbs.
What is ratio?An ordered pair of numbers a and b, written as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could write the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls). The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two things.
Given ratio,
1 peso/0.053 dollar
0.053 dollar/1 peso
1 kg/2.2 lbs
2.2 lbs/1 kg
0.83 dollar/1lbs * 2.2 lbs/1 kg* 1 peso/ 0.053 dollar = 34.45 peso/kg
The value of the given ratio is 34.45 pesos per kilogram because the ratios are 1 peso/0.053 dollar, 0.053 dollar/1 peso, 1 kg/2.2 lbs, 2.2 lbs/1 kg, 0.83 dollar/1lbs.

If a=-1+2i and b=5, then find the value of the a^2b in fully simplified form.
The value of the algebraic expression is:
a^2*b = -15 + 20i
How to find the value of the expression?
Here we have the following expression:
a^2*b
And we want to use the values:
a = -1 + 2i
b = 5
Replacing these values in the expression we will get:
(-1 + 2i)^2*5
Expanding the first part we get:
(-1 + 2i)*(-1 + 2i) = (-1)*(-1) + (-1)*(2i) + (2i)*(-1) + (2i)*(2i)
= 1 - 2i - 2i - 4
= -3 + 4i
Replacing that in the expression we get:
(-1 + 2i)^2*5 = (-3 + 4i)*5 = -3*5 + 4i*5 = -15 + 20i

Alan has 229 songs on a playlist. He's categorized them in the following manner: 11 rock, 21 Latin American, 46 gospel, 30 country, 39 rap, 25 classical, and 57 pop. If Alan begins listening to his playlist on shuffle, what is the probability that the first song played is a rock song?
=================================================
Work Shown:
11 rock songs
229 total
11/229 is the probability of randomly selecting a rock song. The fraction doesn't reduce since 11 and 229 have no factors in common (other than 1).
If you wanted to convert to decimal form, then 11/229 = 0.04803 approximately. This converts to about 4.803%

What is triangle?
A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given are the sides of triangle as AB = 18cm, BC = 18cm, AC = 16cm.
The given triangle is a isosceles triangle with two sides equivalent. Angles opposite to these sides will be equal. So, we can write -
2∠x + ∠y = 180°
from the figure, it can be seen that angle B is 5.38 degrees.
2∠x + 5.38 = 180
2∠x = 174.62
∠x = 87.31°
Therefore, the angle measurements are 5.38°, 87.31° and 87.31°.

Answer:
1.667×10^-12.857×10^-1Step-by-step explanation:
You want the result of a division operation performed on numbers written in scientific notation.
In each case, the result number will have a repeating decimal fraction. We show 4 significant figures in the answer. The number of significant figures you need to use will depend on what you're using the answer for. If you are required to match the precision of the numbers here, you will want to use 1 significant figure.
The rules of exponents apply, so the exponent of the result will be the difference of the exponents of numerator and denominator. As always, if the numerator mantissa is smaller than the denominator mantissa, the result will be a fraction, so adjustment of the exponent will be necessary.
5×10^-10/(3×10^-9)= (5/3)×10^(-10-(-9)) = 1.667×10^-1
1×10^-9/3.5×10^-9= (1/3.5)×10^(-9-(-9)) = 0.2857×10^0 = 2.857×10^-1

Additional comment
Any scientific or graphing calculator and any spreadsheet can accept input in scientific notation and format the output in the same way.
You need to be careful with the way you enter the multiplier. Most calculating platforms accept the E notation shown in the attachment. If you use multiplication (×10^-9, for example), then the denominator number will need to be enclosed in parentheses. The third line of the second attachment shows the result of not using parentheses: the multiplier intended for the denominator instead multiplies the result of the division. (This behavior is required by the Order of Operations.)
