The peak flow is 1 CIA. The Rational Method is used to calculate the peak discharge or peak flow rate in a catchment. This formula is commonly used in engineering and hydrology, and it's utilized for designing stormwater runoff control measures such as detention ponds, rain gardens, and storm sewers.

In this scenario, we are given that the Time of concentration of a watershed is 30 minutes, and the rainfall duration is also 30 minutes. By using the Rational Method formula, we can determine the peak flow rate. The formula is as follows:

Q = CIA, where Q is the peak flow rate, C is the runoff coefficient, I is the rainfall intensity, and A is the drainage area. Since we're given that the rainfall duration is 30 minutes, we can use the rainfall intensity equation to find out the I value. Using a rainfall intensity map, we can estimate that the rainfall intensity for a 30-minute duration is 2 inches per hour or 3.33 cm/hr. Now, we can substitute the given values into the Rational Method formula:

Q = CIA

Q = (0.4) (3.33) (A)

Q = 1.332 A

Q = 1.3A

According to the Rational Method, the peak flow rate is Q = 1.3A. Therefore, the answer is 1 CIA.

Explanation:

Answer:

y = 4x - 18

Step-by-step explanation:

Write out y = mx + b.

The slope of the line in question is 4.  Thus we have y = 4x + b.

Finally, substitute -6 for y, 3 for x and solve for b:

-6 = 4(3) + b, or -6 = 12 + b.  Then b = -18, and the equation of this line is

y = 4x - 18

Answer:

18

Step-by-step explanation:

y=4x-18 is the solution and 18 is the y-intercept because the b (18) is the y-intercept.

Answer:

y = 4(2x) - 3

Step-by-step explanation:

linear functions are written like y =mx + b or y = kx

They must have "x" in it and there cannot be a square root or exponent near x.

y = -2 does not have an x therefore it is not a linear equation

x² + y = 1 has an exponent so write away we can eliminate this because linear equations cant have exponents

y = 2√x has a square root so we can eliminate this answer choice as well

y = 4(2x) - 3 simplifies to y = 8x - 3 which is put in y = mx + b which is linear therefore this is the answer

To write the center and radius of a circle, we need to have the equation of the circle in standard form, which is: (x - h)² + (y - k)² = r² where (h, k) is the center of the circle and r is the radius.

A circle is a geometrical figure that is defined as a closed shape where all the points on the boundary of the shape are at an equal distance from the center point. The center of a circle is the point which is equidistant from all points on the circumference of the circle. To determine the center of a circle, we need to follow some steps:

Step 1: Identify the coordinates of three points on the circle

To find the center of a circle, we need to know the coordinates of at least three points on the circumference of the circle. The coordinates of these points can be determined by measuring the distance of the points from the x-axis and y-axis.

Step 2: Find the perpendicular bisectors of two chords

Once we have identified three points on the circle, we need to find the perpendicular bisectors of two chords. A chord is a line segment that connects two points on the circumference of the circle. The perpendicular bisector of a chord is a line that is perpendicular to the chord and passes through the midpoint of the chord.

Step 3: The intersection of perpendicular bisectors is the center of the circle

The perpendicular bisectors of two chords will intersect at a single point. This point is the center of the circle. To verify that this point is indeed the center, we can measure the distance from the center point to the three points on the circle. If the distances are equal, then the point is indeed the center of the circle.

In summary, to find the center of a circle, we need to identify the coordinates of at least three points on the circumference of the circle, find the perpendicular bisectors of two chords, and then find the intersection of the two perpendicular bisectors. This point is the center of the circle.

The slope of the line forming the smallest right triangle, when a line is drawn through the point (1, 2), is 2.

The slope of the line forming the smallest right triangle with the positive x and y axes, when a line is drawn through the point (1, 2), can be determined as follows.

First, let's consider the two axes as the legs of the right triangle, and the line drawn through (1, 2) as the hypotenuse. The slope of the hypotenuse can be calculated by finding the difference in y-coordinates divided by the difference in x-coordinates between the two endpoints.

Since the x-coordinate of the point where the line intersects the x-axis is 0 (positive x-axis), and the y-coordinate of the point where the line intersects the y-axis is 0 (positive y-axis), the difference in y-coordinates is 0 - 2 = -2, and the difference in x-coordinates is 0 - 1 = -1.

Therefore, the slope of the line forming the smallest right triangle is -2/-1 = 2.

If the composite functions f(g(x)) and g(f(x)) both equal to x, then the function g is the Inverse function of f.

A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. 

Let us take the Example.

Suppose f(x)= x/4 and g(x)=4x.

Let x=1

then f(g(x))= f(g(1))=f(4)=1

Based on the formula of the quadratic function y=-x^2+6x-5, we know that its graph is a downward-facing parabola that opens wide, with a vertex at (3,-14), and an axis of symmetry at x=3.

Based on the formula of the quadratic function y=-x^2+6x-5, we can determine several properties of its graph, including its shape, vertex, and axis of symmetry.

First, the negative coefficient of the x-squared term (-1) tells us that the graph will be a downward-facing parabola. The leading coefficient also tells us whether the parabola is narrow or wide. Since the coefficient is -1, the parabola will be wide.

Next, we can find the vertex using the formula:

Vertex = (-b/2a, f(-b/2a))

where a is the coefficient of the x-squared term, b is the coefficient of the x term, and f(x) is the quadratic function. Plugging in the values for our function, we get:

Vertex = (-b/2a, f(-b/2a))

= (-6/(2*-1), f(6/(2*-1)))

= (3, -14)

So the vertex of the parabola is at the point (3,-14).

Finally, we know that the axis of symmetry is a vertical line passing through the vertex. In this case, it is the line x=3.

The number of degrees of freedom in a real symmetric matrix is equal to the number of unique entries in the matrix.

If a matrix is n x n, then it has n^2 total entries. However, since it is symmetric, the diagonal entries are repeated, leaving (n^2 + n) / 2 unique entries. Therefore, the number of degrees of freedom in a real symmetric matrix is (n^2 + n) / 2.

The number of degrees of freedom in a real diagonal matrix is simply the number of diagonal entries, which is equal to the dimension of the matrix. Therefore, if the matrix is n x n, the number of degrees of freedom is n.

Finally, the number of degrees of freedom in a real orthogonal matrix is equal to the number of independent variables needed to specify the matrix. An orthogonal matrix is defined as a matrix whose columns are orthonormal, which means that they are unit vectors that are orthogonal (perpendicular) to each other. Since each column must be a unit vector, there are n independent variables needed to specify the first column (the magnitude and direction), n-1 independent variables needed to specify the second column (since it must be orthogonal to the first), and so on. Therefore, the total number of degrees of freedom in a real orthogonal matrix is the sum of the integers from 1 to n-1, which is (n-1)n/2.

Using the hint given in the question, we can add up the number of degrees of freedom in a real diagonal matrix and a real orthogonal matrix to get (n + (n-1)n/2), which simplifies to (n^2 + n)/2, which is the same as the number of degrees of freedom in a real symmetric matrix.

The correct answer is C. open parenthesis negative infinity, -4 close parenthesis union open parenthesis -2, infinity close parenthesis.

Based on the description of the graphs of f(x) and g(x), the intervals in which both functions are increasing can be determined.

For function f(x), it is stated that it increases from the left, passes through (-5, -4), reaches a local maximum at (-4, 0), goes back down through (-3, -2) to a local minimum at (-2, -4), and then goes back up through (-1, 0) to the right.

For function g(x), it is mentioned that one piece of the rational function increases from the left in quadrant 2, passing through (-6, 2) and (-3, 5), and asymptotically approaches the line y = 1.

Another piece of the function is asymptotic to the line x = -2 and increases from the left in quadrant 3, passing through (-1, -3) and (2, 0).

To find the intervals where both functions are increasing, we need to identify the overlapping regions of increasing behavior for both functions.

Based on the given information, the only overlapping interval of increasing behavior for both functions is:

The value of the constant of variation is 2,199 feet. The speed of the another rider is 87.96 feet/sec.

Let there are two variables p and q

Then, p and q are said to be directly proportional to each other if

 p = kq

where k is some constant number called the constant of proportionality.

This directly proportional relationship between p and q is written as

 p∝q  where that middle sign is the sign of proportionality.

In a directly proportional relationship, increasing one variable will increase another.

Now let m and n be two variables.

Then m and n are said to be inversely proportional to each other if

\(m = \dfrac{c}{n} \\\\ \text{or} \\\\ n = \dfrac{c}{m}\)

(both are equal)

where c is a constant number called the constant of proportionality.

This inversely proportional relationship is denoted by

\(m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}\)

As visible, increasing one variable will decrease the other variable if both are inversely proportional.

A.) The time it takes to complete a go-cart course is inversely proportional to the average speed of the go-cart. Therefore, the relationship can be written as,

Average speed ∝ (1/time)

Now, if the constant of variation is introduced then the relationship can be written as,

Average speed = k(1/time)

Substituting the values, we will get,

\(73.3\frac{ feet}{second}= k \times \dfrac{1}{30\ seconds}\\\\73.3 \frac{ feet}{second}\times 30\ seconds = k\\\\k = 2,199\ feet\)

Hence, the value of the constant of variation is 2,199 feet.

B.) The speed of the another rider is,

Average speed = k(1/time)

Average speed = 2,199×(1/25) feet/sec

Average speed = 87.96 feet/sec

Hence, the speed of another rider is 87.96 feet/sec.

The ratio of false positives to true positives is 8 over 54.

According to the Question

Results of a strep throat test performed on a sample of 400 ill people are displayed in the table's data. People who have the flu and those who don't are separated into two categories. The patients are then separated into groups based on whether they tested positive or negative for strep throat within each of these categories.

We must first define what a true positive and a false positive are in order to calculate the ratio of false positives to true positives. A patient who tests positive for strep throat but does not actually have the illness is said to have a false positive. The 8% of patients in this instance who tested positive for strep throat but did not have the flu would fall under that category. A patient who tests positive for strep throat and truly has the illness is said to have a true positive. That would be the 54% of patients who tested positive for both the flu and strep throat in this instance.

We divide the percentage of false positives (8%) by the percentage of true positives (54%), which gives us the ratio of false positives to true positives.

As a result, the ratio becomes 8% / 54%, or 8/54.

It's critical to remember that this ratio is dependent on the sample and test performed and may not be the same for different populations or testing methodologies.
