What is function?In mathematics, a function is a rule that associates each element in one set (called the domain) to a unique element in another set (called the range). Functions are one of the most important concepts in mathematics and have a wide range of applications in various fields.
A function is usually denoted by a letter, such as f(x), where x is an element in the domain and f(x) is the corresponding element in the range. The domain of a function is the set of all possible values of x for which the function is defined, and the range is the set of all possible values of f(x).
To graph the piecewise function f(x), we will graph each part of the function separately.
For -1 < x < 2, the function is given by f(x) = -2x - 3. This is also a linear function with a slope of -2 and y-intercept of -3. The graph of this part of the function is a straight line passing through (-1, 1) with a gentle slope, extending towards positive x-values until it reaches x=2.
For x ≥ 2, the function is given by f(x) = 5. This is a horizontal line at y=5, which is a constant function. The graph of this part of the function is a horizontal line at y=5 starting from x=2.

y = $25 + $10*w
Where w is the number of weeks.
Now we want to graph this, to do so, we just need to find two points on the line.
if w = 0
y = $25 + $10*0 = $25
if w = 6
y = $25 + $10*6 = $85
So we need to graph the points (0, 25) and (6, 85) and connect them witha line.

Gold Corp. has an ROE of 12% and a payout ratio of 20%.
What is its sustainable growth rate? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
The sustainable growth rate is calculated by subtracting the payout ratio from the ROE.
The sustainable growth rate is calculated by subtracting the payout ratio from the ROE. To calculate the sustainable growth rate for Gold Corp., we must first calculate the retention ratio. The retention ratio is calculated by subtracting the payout ratio from 100%. In this case, the retention ratio would be 100% - 20% = 80%. The sustainable growth rate is then calculated by multiplying the retention ratio by the ROE. In this case, the equation would be 80% * 12% = 9.6%. The sustainable growth rate for Gold Corp. is 9.6%, which can be rounded to 9.6%.

Find an infinite set of positive integers such that the sum of any two distinct elements has an even number of distinct prime factors
One possible set of positive integers that satisfies the given condition is the set of powers of 2, i.e., {2, 4, 8, 16, 32, ...}.
To see why this set works, note that any two distinct powers of 2 have a different binary representation, differing in at least one bit. This means that their sum will have one more "1" bit in its binary representation than either of the two numbers being added.
Since any prime number greater than 2 is odd, it follows that the sum of any two distinct powers of 2 will have an even number of distinct prime factors, namely the powers of 2 that appear in its binary representation.
First, let's note that every positive integer can be uniquely expressed as a product of prime powers, e.g., 36 = 2^2 * 3^2. The prime factors of an integer are the primes that appear in its prime factorization, e.g., the prime factors of 36 are 2 and 3.

Explanation:
The y-axis reflection rule is:
[tex](\text{x},\text{y})\to (-\text{x},\text{y})[/tex]
The x coordinate flips from positive to negative, or vice versa. The y coordinate stays the same.
So for example, the point B(-6,4) moves to B ' (6, 4).

a: 1.711
b: 2.064
c: 2.492
d: 2.069
We can see from a t-table with right-tail probabilities that the probability value that is closest to 2.5% is 0.0250, which is represented by a t-score.
The row in the table that corresponds to the number of degrees of freedom (df) must be found before the column that corresponds to the desired level of significance or alpha value in order to use the t-table to determine a t-score that cuts off a specific percentage in the upper tail for a t-distribution with a given number of df.
Since there are 24 degrees of freedom in this situation, we need to identify the t-score that removes 2.5% of the upper tail. We will be looking at the column for the right-tail probabilities because this test has one tail (upper tail), making it a one-tailed test.
Therefore, We can see from a t-table with right-tail probabilities that the probability value that is closest to 2.5% is 0.0250, which is represented by a t-score.

Find the surface area of the composite figure. 5.cm idem 10cm 8cm 4cm 24 12cm If you'd like, SA = [Ml] cm2 jest calculator. 4cm 5cm
To find the surface area of the composite figure, we need to break it down into simpler shapes and add up their surface areas. From the given dimensions, we can see that the composite figure consists of two rectangular prisms and a triangular prism.
The dimensions of the rectangular prism are 10 cm (length), 8 cm (width), and 24 cm (height). Therefore, its surface area is:
SA1 = 2lw + 2lh + 2wh
SA1 = 2(10 cm)(8 cm) + 2(10 cm)(24 cm) + 2(8 cm)(24 cm)
SA1 = 160 cm^2 + 480 cm^2 + 384 cm^2
SA1 = 1024 cm^2
The dimensions of the triangular prism are 5 cm (base), 12 cm (height), and 8 cm (length). Therefore, its surface area is:
SA2 = lb + 2[(1/2)bh + lh]
SA2 = (8 cm)(5 cm) + 2[(1/2)(5 cm)(12 cm) + (8 cm)(12 cm)]
SA2 = 40 cm^2 + 240 cm^2 + 96 cm^2
SA2 = 376 cm^2
The dimensions of the rectangular prism on top are 4 cm (length), 5 cm (width), and 12 cm (height). Therefore, its surface area is:
SA3 = 2lw + 2lh + 2wh
SA3 = 2(4 cm)(5 cm) + 2(4 cm)(12 cm) + 2(5 cm)(12 cm)
SA3 = 40 cm^2 + 96 cm^2 + 120 cm^2
SA3 = 256 cm^2
To find the total surface area of the composite figure, we add the surface areas of the three shapes:
Total surface area = SA1 + SA2 + SA3
Total surface area = 1024 cm^2 + 376 cm^2 + 256 cm^2
Total surface area = 1656 cm^2
Therefore, the surface area of the composite figure is 1656 cm^2.
Plans were made for a rectangular garden to be planted outside a library. The plans use a scale of 1.6cm=2cm. If the Girardeau is 14cm by 10cm on the scale, find the actual dimensions
The actual dimensions of the rectangular garden are 17.5 cm by 12.5 cm
How to determine the actual dimensionsFrom the question, we have the following parameters that can be used in our computation:
Scale: 1.6 cm = 2 cm
A scale is the ratio of the size of the drawing to the size of the actual object.
Given that the dimension is
14 cm by 10 cm
Using the above as a guide, we have the following equation
Actual = 14 * 2/1.6 cm by 10 * 2/1.6 cm
Evaluate
So, we have the following representation
Actual = 17.5 cm by 12.5 cm
Hence, the actual is 17.5 cm by 12.5 cm

Determine the value of h such that the matrix is the augmented matrix of a consistent linear system.[1 h 43 6 8]
The value of h such that the matrix is the augmented matrix of a consistent linear system is 2
For the given matrix to be the augmented matrix of a consistent linear system, we need to check whether the matrix is in row echelon form or not. If the matrix is in row echelon form and the last row is not all zeros, then the linear system is consistent.
We can use elementary row operations to transform the matrix into row echelon form.
[tex]\left[\begin{array}{ccc}1&h&4\\3&6&8\end{array}\right][/tex]
R2 <- R2 - 3R1
[tex]\left[\begin{array}{ccc}1&h&4\\0&6-3h&-4\end{array}\right][/tex]
The matrix is in row echelon form. Now, we need to check whether the last row is all zeros or not.
If 6-3h = 0, then the last row will be all zeros, which implies that the linear system is inconsistent.
If 6-3h ≠ 0, then the last row will not be all zeros, which implies that the linear system is consistent.
Therefore, we need to solve the equation 6-3h = 0 to determine the value of h that makes the linear system consistent.
6-3h = 0
3h = 6
h = 2
So, the value of h that makes the matrix the augmented matrix of a consistent linear system is h = 2.

what is the unknown number in sequence 2 in the chart? What rule can you write that relates sequence 2 to sequence 1
The tenth term of the second sequence is 80 and sequence 2 is formed by multiplying by 2 to sequence 1. Then the correct option is C.
What is an arithmetic sequence?Let a₁ be the first term and d be a common difference. Then the nth term of the arithmetic sequence is given as,
aₙ = a₁ + (n - 1)d
From the table, the first term of the first sequence is 4 and the first term of the second sequence is 8. If the first sequence is multiplied by 2 then we obtain the second sequence.
The common difference of the second sequence is given as,
d = 16 - 8
d = 8
Then the tenth term of the second sequence is given as,
a₁₀ = 8 + (10 - 1) x 8
a₁₀ = 8 + 72
a₁₀ = 80
The tenth term of the second sequence is 80 and sequence 2 is formed by multiplying by 2 to sequence 1. Then the correct option is C.
