Answer:
The nth term rule for an arithmetic sequence with a first term of -10 and a common difference of 0.5 is given by:
an = a₁ + (n-1)d
where a₁ = -10 and d = 0.5.
Substituting these values into the formula gives:
an = -10 + (n-1)0.5
Simplifying this expression gives:
an = -10 + 0.5n - 0.5
an = -10 + 0.5n - 0.5
an = -10 + 0.5n - 0.5
an = -10 + 0.5n - 0.5
an = -10 + 0.5n - 0.5
an = -10 + 0.5n - 0.5
an = -0.5n - 9.5

What is Quadratic Equation?
A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c = 0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
Given data ,
Let the function be f ( x ) = y
And , y = x² + 2x - 8
So , f ( x ) = x² + 2x - 8
Substituting the value for x in the equation , we get
When x = -3
f ( -3 ) = ( -3 )² + 2( -3 ) - 8
= 9 - 6 - 8
= 9 - 14
f ( -3 ) = -5
When x = 1
f ( 1 ) = ( 1 )² + 2( 1 ) - 8
= 1 + 2 - 8
= 3 - 8
f ( 1 ) = -5
Hence , the value of y = -5

The owners of a manufacturing company conducted a survey to determine the mean income of the customers who prefer the company’s brand of clothing. From a random sample of 100 customers, it was determined that their mean income was $47,600. Which conclusion can be made based on this information?
The total population mean must be much greater than $47,600 because there are more people in the total population.
The total population mean cannot be determined by such a small random sample.
The total population mean must be close to $47,600 based on statistical inference.
The total population mean must be much less than $47,600 because, out of a sample of 100, a few people with a very high mean income would skew the data.
The total population mean must be close to $47,600 based on statistical inference.
The entire population mean must be close to $47,600. Then the correct option is C.
What is Mean?The mean is the simple definition of the average of a bunch of numbers. In statistics, one of the markers of central tendency is the mean.
The average is referred to as the arithmetic mean.
It's the ratio of the number of real observations to the total number of observations.

Which image shows triangle A dilated by a scale factor of 2 with a center at the origin?
The triangle ABC undergoes a dilation of scale factor 2 centered at the origin.
Dilation About the Origin
Given a point P(x,y), its dilation about the origin by a scale factor of k maps the point to a point P'(kx,ky).
If we are given the dilated point, then we can find the original point by dividing by the scale factor.
Triangle ABC was dilated by a scale factor of 2 about the origin mapping it to triangle A'B'C' with vertices A'(-4,4), B'(-4,6), and C(2,4).
The coordinates of triangle ABC are:
A=(-4/2,4/2) = (-2,2)
B=(-4/2,6/2) = (-2,3)
C=(2/2,4/2) = (1,2)
The coordinates of ABC are respectively (-2,2), (-2,3), and (1,2).
Hence the answer is the triangle ABC undergoes a dilation of scale factor 2 centered at the origin.

Suppose you have a friend and that friend lives 3 miles away. You ride your bike there but on the way there you forgot you had chores to do. So you continue to ride there to tell your friend that you can't stay and immediately turn back around. Since you're in a hurry, you ride 5 mph faster than your trip to your friend. The total round trip took 30 minutes.
The chores overshadowed the joy of our Reunion, learned a valuable lesson about managing time and prioritizing obligations
Embarking on a bike ride to visit a friend who lives 3 miles away, little did I know that a looming sense of forgotten chores would soon disrupt my plans. Determined to fulfill my obligations, I mustered the strength to continue riding towards my friend's house, albeit with a heavy heart.
I pedaled towards my destination, the weight of my impending chores grew heavier with each passing moment. Thoughts of unfinished tasks occupied my mind, and I knew that I couldn't stay for long once I reached my friend's place. However, in my haste, a newfound urgency propelled me forward, and I found myself pedaling at a speed 5 mph faster than my initial journey.
With this increased velocity, the return trip promised to be swifter, yet time was slipping away. My mind raced as I calculated the implications of my predicament. The total round trip, comprising both the journey to my friend's house and the hurried return, needed to be accomplished within a tight time frame of 30 minutes.
As I approached my friend's house, I realized that I had no choice but to deliver my news swiftly and immediately turn back around. The momentary joy of reunion would be overshadowed by the pressing chores that awaited me. Regrettably, I bid my friend a hasty farewell, explaining the circumstances that compelled my premature departure.
Once on my bike again, I kicked up the pace, utilizing the extra speed to my advantage. The wind rushed past my face as I hurriedly retraced my path, pushing myself to complete the return trip as swiftly as possible. The seconds ticked away relentlessly, as the pressure mounted to make it back within the allocated timeframe.
In a flurry of determination, I managed to reach home just in the nick of time, fulfilling my duties and responsibilities. Exhausted but relieved, I contemplated the whirlwind of events that had transpired within the span of this half-hour adventure.

Fishermen in the said region struggled due to the massive deaths of fish. The student was called to investigate the cause of this sudden incident. The student analyzed the massive deaths of fish through water sampling and Fish Necropsy. Fish Necropsy is the procedure used to examine the cause of death of the fish through dissection. Fresh dead fishes usually have clear eyes, good coloration, red to pink gills, and should not have a bad odor. Depletion of dissolved oxygen and lesions among fishes were the results found after analyzing water quality and fish necropsy. In this experiment, the students used a LABSTER simulation to inspect the biological substance in the water using a microscope, confirming the findings of the data collected. The laboratory experiment aims to determine the underlying etiology of the causes of death of the fishes.
Dissolved oxygen refers to the level of oxygen present in water. It is considered the major indicator of water quality. Normally, dissolved oxygen in freshwater ranges from 7.56 mg/L to 14.62 mg/L (Minnesota Pollution Control, 2009). When the dissolved oxygen concentration drops to less than two mg/L, it is referred to as hypoxia. When completely depleted, it is called anoxia. The dissolved oxygen level varies depending on the water classification, temperature, streamflow, algal growth, and nutrient content of water (USSG.gov).

The research aims to find out how the depletion of dissolved oxygen levels and fish lesions led to the death of the fish. It would also establish the range of dissolved oxygen and other environmental factors necessary for the survival of fish. The scope of the study covered the entire region affected by the massive death of fish.
