Graph the image of this figure after a dilation with a scale factor of 3 centered at (−7, −6). Use the polygon tool to graph the dilated figure.
The dilation transformation gives an image that is similar to the pre-image
but have a different size.
Please find attached the required graph of the image created with MS ExcelReasons:
Points on the figure are; A(-7, -3), B(-3, -2), C(-4, -5)
The scale factor of dilation = 3
The center of dilation = (-7, -6)
Required:
The graph of the image following the dilation.
Solution:
The given points relative to the center of dilation are;
(-7 - (-7), -3 - (-6)) = (0, 3)
(-3 - (-7), -2 - (-6)) = (4, 4)
(-4 - (-7), -5 - (-6)) = (3, 1)
Following the dilation gives;
3 × (0, 3) = (0, 9)
3 × (4, 4) = (12, 12)
3 × (3, 1) = (9, 3)
Adding the coordinates of the center of dilation to the above relative points of the image gives;
Location of point A' = (0 + (-7) , 9 + (-6)) = (-7, 3)
Location of point B' = (12 + (-7) , 12 + (-6)) = (5, 6)
Location of point C' = (9 + (-7) , 3 + (-6)) = (2, -3)
Therefore, the image is; A'(-7, 3), B'(5, 6), C'(2, -3)

What is the most likely consequence of open pit mining on plant life? a. A dramatic reduction in the variety of plant species b. An increase in the number of plant species c. The complete loss of plant life in the area occupied by the surface mine d. A temporary decrease in plant populations please select the best answer from the choices provided.
The most likely consequence of open pit mining on plant life is a dramatic reduction in the variety of plant species. Open pit mining involves removing large amounts of rock and soil to extract valuable minerals. This process destroys the natural habitat of plants and disrupts the ecological balance.The correct answer is option A.
Here is a step-by-step explanation:
1. Open pit mining involves digging a large hole in the ground to extract minerals such as coal, gold, or copper. This process often requires the removal of trees, vegetation, and topsoil from the area.
2. The removal of vegetation and topsoil disrupts the natural ecosystem, as plants play a vital role in supporting other organisms. They provide food, shelter, and oxygen for animals, insects, and microorganisms.
3. The destruction of plants in the area leads to a loss of habitat for various plant species. Many plants are unable to survive or adapt to the harsh conditions created by open pit mining, such as exposure to sunlight, wind, and erosion.
4. The disturbed soil and exposed rock surfaces are often unable to support the growth of diverse plant species. This results in a reduction in the variety of plants that can grow in the area.
5. Additionally, the mining process may introduce pollutants and contaminants into the soil, water, and air, further damaging plant life.
In summary, open pit mining has a significant negative impact on plant life, resulting in a dramatic reduction in the variety of plant species. The destruction of habitat, disturbance of soil and rock surfaces, and pollution are all contributing factors to this consequence.

Newton’s law of cooling states that for a cooling substance with initial temperature t0, the temperature t(t) after t minutes can be modeled by the equation t(t)=ts+(t0−ts)e−kt, where ts is the surrounding temperature and k is the substance’s cooling rate. A liquid substance is heated to 80°c. Upon being removed from the heat, it cools to 60°c in 15 min. What is the substance’s cooling rate when the surrounding air temperature is 50°c? round the answer to four decimal places. 0. 0687 0. 0732 0. 0813 0. 872.
The cooling rate of the substance is approximately 0.0732.
According to the statement, the Newton's law of cooling is defined by the following formula:
[tex]T(t) = T_{s} + (T_{o}-T_{s})\cdot e^{-k\cdot t}[/tex] (1)
Where:
[tex]T_{s}[/tex] - Final temperature, in degrees Celsius.[tex]T_{o}[/tex] - Initial temperature, in degrees Celsius.[tex]t[/tex] - Time, in minutes.[tex]k[/tex] - Cooling rate, in [tex]\frac{1}{min}[/tex].[tex]T(t)[/tex] - Current temperature, in degrees Celsius.Please notice that substance reaches thermal equilibrium when [tex]T(t) = T_{s}[/tex], that is when temperature of the substance is equal to the temperature of surrounding air.
If we know that [tex]T_{o} = 80\,^{\circ}C[/tex], [tex]t = 15\,min[/tex], [tex]T_{s} = 50\,^{\circ}C[/tex] and [tex]T(15) = 60\,^{\circ}C[/tex], then the cooling rate of the substance is:
[tex]60 = 50 + (80 - 50)\cdot e^{-15\cdot k}[/tex]
[tex]\frac{60-50}{80-50}= e^{-15\cdot k}[/tex]
[tex]\frac{1}{3} = e^{-15\cdot k}[/tex]
[tex]k = -\frac{1}{15}\cdot \ln \frac{1}{3}[/tex]
[tex]k \approx 0.0732[/tex]
The cooling rate of the substance is approximately 0.0732.

Translate: i am hungry. Yo soy hambre. Yo estoy hambre. Yo tengo hambre. Yo es hambre.
Happy Holidays!
Yo tengo hambre.
Yo = I
Tengo = have (I form)
Hambre = hunger
Even though this literally translates to "I have hunger", this expression is used to say the equivalent "I am hungry".
The correct translation of "I am hungry" in Spanish is: "Yo tengo hambre."
Thus, option (c) is correct.
"Yo soy hambre" is not the correct translation.
In Spanish, "soy" means "am" and "hambre" means "hungry," but they are not used together in this context to mean "I am hungry."
"Yo estoy hambre" is also not the correct translation.
"Estoy" means "am" and "hambre" means "hungry."
However, in Spanish, the correct way to express hunger is by using the phrase "tener hambre."
"Yo tengo hambre" is the correct translation.
"Tengo" means "I have," and "hambre" means "hunger."
So, "Yo tengo hambre" translates directly to "I have hunger," which is the equivalent of "I am hungry" in English.
The phrase "Yo es hambre" is not grammatically correct in Spanish.
Thus, option (c) is correct.
