The graph of a sinusoidal function intersects its midline at (0,-6) and then has a minimum point at (2.5,-9)

Answer:

a) The function to represent the scenario would be:

f(x) = 56 - 8x

b) To find out how many sips Anna can take before she needs to refill, we need to find when the water bottle is empty.

To do this, we can set f(x) = 0 and solve for x:

0 = 56 - 8x

8x = 56

x = 7

So, Anna can take 7 sips before she needs to refill.

c) A graph to represent this situation would be a straight line with a slope of -8 and y-intercept of 56.

d) The domain of the function is the set of all possible input values, or in this case, the number of sips Anna takes.

As Anna can take any whole number of sips, the domain of the function is the set of all non-negative integers:

{x | x ∈ Z, x ≥ 0}

We can represent how many sips Anna takes from her water bottle with the function y = 56 - 8x. Anna can take 7 sips before she needs a refill. The graph of this function is a straight line that starts at (0, 56) and ends at (7, 0). The domain in set notation is {x|x is an integer and 0 <= x <= 7}.

a) We can represent this scenario with a function, where the amount of water in the bottle depends on how many sips Anna has taken. This is a linear function because each sip Anna takes decreases the amount of water in the bottle by a constant amount. The function could be written as: y = 56 - 8x, where y represents the amount of water in the bottle, and x represents the number of sips Anna has taken.

b) To find out how many sips Anna can take before she needs to refill the bottle, we set y to 0 in our function: 0 = 56 - 8x. Solving for x gives us x = 7. Therefore, Anna can take 7 sips before she needs to refill the bottle.

c) A graph representing this situation would be a straight line starting at (0, 56) on the y-axis, and going down 8 units for each step along the x-axis, until reaching x=7.

d) The domain in set notation for this function would be {x|x is an integer and 0 <= x <= 7}.

The actual number of people in 10 years could be 57,000 or 56,000. The equation of the trend line is y=1.9x+21, so for any year x, the population y can be found using this equation. To find the population in 16 years, when the population is 52,900, we can plug in x=16 and solve for y to find y=52,900. To find the population in 10 years, when the population is 2,000 people from what the trend line shows, we can plug in x=10 and solve for y to find y=50,900. Since the population should be 2,000 more, the actual population in 10 years is either 57,000 (50,900 + 2,000) or 56,000 (50,900 + 1,000).

To write an absolute value inequality from a line graph, we need to identify the inequality sign and determine the interval(s) of x-values that make the inequality true.

Here are the steps to write an absolute value inequality from a line graph:

Identify the inequality sign: If the graph is a solid line, the inequality is "equals to", if the graph is dashed, the inequality is "not equal to", if the graph is a solid line to one side and a dashed line to the other side, the inequality is "greater than or equal to" or "less than or equal to".

Determine the interval(s) of x-values that make the inequality true: The x-values for which the graph is above the x-axis represent the solution set of the inequality when the inequality sign is "greater than" or "greater than or equal to", and the x-values for which the graph is below the x-axis represent the solution set of the inequality when the inequality sign is "less than" or "less than or equal to"

Write the inequality: Using the information from step 1 and 2, we can write the inequality in the form of |x-h| operator k, where h is the x-coordinate of the vertex, k is the distance of the vertex to the x-axis and operator is the inequality sign determined in step 1.

Since all the given points are to be covered in the specified order.

Find the minimum number of steps required to reach from a starting point to next point, then the sum of all such minimum steps for covering all the points would be the answer.

One way to reach from a point (x1, y1) to (x2, y2) is to move abs(x2-x1) steps in the horizontal direction and abs(y2-y1) steps in the vertical direction, but this is not the shortest path to reach (x2, y2).

The best way would be to cover the maximum possible distance in a diagonal direction and remaining in horizontal or vertical direction.

If we look closely this just reduces to the maximum of abs(x2-x1) and abs(y2-y1).

Traverse for all points and summation of all diagonal distance will be the answer.

The answer to the first, third and fourth part is inductive reasoning and the answer to the second and fifth part is deductive reasoning.

The first example is an example of Inductive reasoning because it is based on a pattern or trend of a sequence of numbers (2, 4, 6, 8) and uses that pattern to make a prediction or generalization about the next number in the sequence (10). This is a common use of inductive reasoning, where observations or data are used to make generalizations about future events or situations.

The second example is an example of Deductive reasoning because it starts with a general statement (all plants need water) and applies it to a specific case (Water Hyacinth) to reach a logical conclusion (Water Hyacinth needs water). This is the classic form of deductive reasoning, where the conclusion follows logically from the premises and can be proven to be true if the premises are true.

The third example is an example of Inductive reasoning because it is based on a pattern or trend of a sequence of numbers (dots in squares) and uses that pattern to make a prediction or generalization about the next number in the sequence (16 dots in the next square).

The fourth example is an example of Inductive reasoning because it is based on a pattern or trend of a sequence of events (pre-school, grade 1, grade 2) and uses that pattern to make a prediction or generalization about the next event in the sequence (the child's next teacher will be female).

(5.097, 7.404) is the 90% confidence interval for the true mean amount of time teenagers from this town watch sports. This can be solved using the concept of standard deviation.

Data dispersion in regard to the mean is quantified by a standard deviation, or "σ". Data are said to be more closely grouped around the mean when the standard deviation is low and more dispersed when the standard deviation is high.

Because it makes measures easier to comprehend when the data is spread, standard deviation is significant. The data's standard deviation will increase as the data's distribution becomes more widely scattered. The deviation of each observed value from the mean is measured using this metric. The majority of data in any distribution will fall within a 2 standard deviation range of the mean.
