The coordinates will be after applying the transformation, I(-5,0) --I'(0, -5), Y(0, 2) - -> Y'(2, 0) and T(4, 4) --> T'(4, 4).
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that:
The graph is shown in the picture.
From the picture the coordinates are:
I(-5,0), Y(0, 2), and T(4, 4)
The transformation rule:
(x, y) --> (y, x)
I(-5,0) --I'(0, -5)
Y(0, 2) - -> Y'(2, 0) and
T(4, 4) --> T'(4, 4)
Thus, the coordinates will be after applying the transformation, I(-5,0) --I'(0, -5), Y(0, 2) - -> Y'(2, 0) and T(4, 4) --> T'(4, 4).

The unit rate in acres of land planned by the workers per day is found is 16/35 acres.
What is meant by rate of doing work?Power refers to the rate of work completion. It is a measure of how much energy is used up each unit of time. The joule per second (J/s) is the unit of power in the SI system.Force applied across a distance is called work. Examples such work include dragging down a confined helium balloon, driving a vehicle up a steep hill, and lifting an article against the gravitational attraction of the Earth. Energy manifests mechanically as work.For the mentioned question-
Total acres of land planted = 2/5 acres.
Total time taken = 7/8 days.
Thus, unit rate in acres per day = Total acres of land planted / Total time taken
unit rate in acres per day = (2/5) / (7/8)
unit rate in acres per day = (2*8)/(5*7)
unit rate in acres per day = 16/35
Thus, unit rate in acres of land planned by the workers per day is found is 16/35 acres.

The volume of a cylinder having height one and half of the radius is 12,936 m3 what minimum square cm of paper is needed to cover the curved surface area of the cylinder? The answer should be 1848m2. please solve my question.
Answer:
Lateral Surface Area = 1848 m^2 (does not include the top and bottom)
Step-by-step explanation:
Vol Cylinder = pi*r^2 *h
h = (3/2)r
Vol = pi*r^2((3/2)r) [We are told that the volume is 12,936 m^3]
pi*r^2((3/2)r) = 12,936 m^3
pi*(3/2)*(r^3) = 12,936 m^3
pi*r^3 = (12,936 m^3)*(2/3)
pi*r^3 = 8,624 m
r^3 = (8,624 m)/(3.14)
r^3 = 2745.1
r = 14.0 m
Lateral Surface = 2*(pi)*r*h [Lateral is just the curved portion of the right cylinder.
Lateral Surface Area = 2*(3.14)*(14.0)(21.0)
Lateral Surface Area = 1848 m^2

B: of the lack of water.
C: sand is such a poor insulator.
D: of the lack of vegetation
There is a dramatic change in desert temperatures from day to night because B. of the lack of water.
Why is there a change in temperature?It should be noted that because the air in the desert is so dry, heat escapes quickly at night, the temperature can vary dramatically from day to night. The temperature during the day averages 38°C, while at night it can drop to -4°C in some deserts. The temperature varies greatly depending on where you are in the desert.
During the day, the sand's radiation from the sun's energy superheats the air, causing temperatures to rise. And, because the desert air is so dry, heat escapes quickly at night, according to NASA. The desert biomes are the driest of all biomes.

The coordinate (4, 3) is the solution of the following system of equations:
y = 1/2x + 1 and y = -x + 7
y = x - 1 and y = 1/4x + 2
The solution implies that the coordinate is the: point of intersection.
What is the Solution to a System of Equations?The solution to a system of equations are the coordinate of the point where the two lines that represent the equations of the system intersect each other. The coordinate of x and the coordinate of y, when plugged into any of the equations would be true.
The graph of the system of equations, y = x - 1 and y = 1/4x + 2 shows that both equations intersect at the point with the coordinate (4, 3) [see the graph in figure 1].
Also, the graph in figure two shows that y = 1/2x + 1 and y = -x + 7 also intersect at (4, 3).
Therefore, we can state that, the system of equations with (4, 3) as the solution are:
y = 1/2x + 1 and y = -x + 7
y = x - 1 and y = 1/4x + 2

Tyree: 6x2 − 5
Ben: x2

Part B: Write an expression that represents the number of cans the friends still need to collect to meet their goal. Show all your work. (5 points)
Answer:
Part A
7x² + 5xy – 3
Part B
2x² – 8xy + 8
Step-by-step explanation:
Part A
the canned food collected so far is the sum of the canned food the three friends have by combining the expression
5xy + 2 + 6x² – 5 + x²
= 6x² + x² + 5xy + 2 – 5
= 7x² + 5xy – 3
Part B
The total of cans the friend need to collect to meet their goal is the canned food collected so far minus their targeted goal
= 9x² – 3xy + 5 – (7x² + 5xy – 3)
= 9x² – 3xy + 5 – 7x² – 5xy + 3
= 9x² – 7x² – 3xy – 5xy + 5 + 3
= 2x² – 8xy + 8

Find the measure of each acute angle in a right triangle where the measure of one acute angle is 8 times the measure of the other acute angle
The measure of the acute angles in the right triangle are 10 and 80 degrees.
How to find the angle of a right angle triangle?A right angle triangle is a triangle that has one of its angles as 90 degrees. The sides of a right angle triangle can be named base on the position of the angles. The sides includes hypotenuse side, opposite side and adjacent side.
The sum of angles in a right angle triangle is 180 degrees.
The other measures of the right triangle are acute angles.
Any angle that measures greater than 0° and less than 90° is called an acute angle.
Hence, let's find the measure of the acute angles
let
x = measure of one acute angle
Hence,
x + 8x + 90 = 180
9x = 180 - 90
9x = 90
x = 90 / 9
x = 10
Therefore, the measure of the acute angles are 10 and 80 degrees.

What will the dividend income be on W number of shares of XYZ stock if XYZ distributes a $Y per share dividend?
Answer:
In general, the dividend income on W number of shares of XYZ stock will be W * Y dollars if XYZ distributes a $Y per share dividend.
Step-by-step explanation:
The dividend income on W number of shares of XYZ stock will be W * Y dollars if XYZ distributes a $Y per share dividend. This is because the dividend income is calculated by multiplying the number of shares that an investor owns by the amount of the dividend per share.
For example, if an investor owns W = 100 shares of XYZ stock and XYZ distributes a $Y = 5 per share dividend, then the investor's dividend income will be 100 * 5 = 500 dollars.
In general, the dividend income on W number of shares of XYZ stock will be W * Y dollars if XYZ distributes a $Y per share dividend.
Determine if the triangles are similar by Angle-Angle similarity
The triangles are similar by Angle-Angle similarity since they are congruent.
What is Angle-Angle Similarity?According to the Angle-Angle Similarity Theorem, if two angles in one triangle are equal to two angles in another triangle, the triangles are similar. The triangles are similar if two pairs of corresponding angles in a pair of triangles are congruent. We know this because if two angle pairs are equal, then the third pair must be equal as well.
Two triangles with two angles, starting with Triangle 1, one measuring 47 degrees and the other measuring 53 degrees, are congruent to two angles in Triangle 2. Following the AA similarity theorem, it is assumed that Triangle 1 is similar to Triangle 2.
In this case, angle MNP = angle QPL (corresponding angles, //lines) (A)
angle QLP is common angle (A)
By AA, the 2 triangles are similar.
