The answer should be 0.625 and if not i tried my best to help.

$72 is 4.5% of 6.25 amount. 6.25 Percentage of  72 is 4.5.

By considering the given information

\(72\times x=4.5\\x=\frac{4.5}{72}\times 100\\ x=6.25\)

A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it. percent, which is a relative value used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

The time required for the population to triple is 7.68 hours. the correct answer is 7.68 hours.

During the exponential phase, the rate of growth of a bacterial population is proportional to the size of the population. If the population doubles in 20.4 minutes, it means that the population is growing at a rate such that it doubles after every 20.4 minutes or every 1.36 hours.

This is because 60/20.4 = 2.94 cycles occur in an hour and 1 cycle corresponds to a doubling of the population. This growth rate can be quantified using the concept of generation time, which is the time taken for the population to double.

Thus, if the population doubles every 1.36 hours, the generation time is 1.36/ln2 = 1.92 hours.

In order to calculate the time required for the population to triple, we need to find out how many generations it takes to achieve this.

Since the population doubles once every 1.36 hours, it will take two generations to double twice or 2 x 1.92 = 3.84 hours for the population to double twice.

Similarly, it will take four generations or 4 x 1.92 = 7.68 hours for the population to double three times.

Thus, the time required for the population to triple is 7.68 hours.

Answer:

m∠2 = 7°

Step-by-step explanation:

The difference of the grandson's age in years and the grandfather's age in years is 77. Therefore, the age of the grandson is 7 years.

A grandson's age in months is equal to his grandfather's age in years.

Recall,

12 months = 1 year

Hence,

let

x = age of grandson in month

It is the same age in years for the grandfather.

Therefore,

x = age of grand father in years

The difference of the grandson's age in years and the grandfather's age in years is 77. Therefore,

x - x / 12 = 77

12x - x/12 = 77

11x / 12 = 77

cross multiply

11x = 924

x = 924 / 11

x = 84

Therefore, the grandson age in in years is 84 / 12 = 7 years.

The error occurred when she incorrectly multiplied the 3 by 75.

Joanie made a mistake in her reasoning by incorrectly multiplying both sides of the equation. Let's go through the steps to see where the error occurred.

The original proportion is:

50/3 = 75/x

To solve for x, one common approach is to cross multiply. This involves multiplying the numerator of the first fraction by the denominator of the second fraction and vice versa. In this case, it would look like:

(50)(x) = (3)(75)

This step correctly cross-multiplies the fractions, resulting in:

50x = 225

Now, let's examine the steps Joanie took:

She multiplied both sides of the equation by x:

50x/3 = 75

Next, she multiplied both sides of the equation by 3:

her results is

50x = 75

This step is incorrect because she didn't multiply both terms in the fraction by 3; she only multiplied the left side term. The correct equation should be:

50x = 225

The error occurred when she incorrectly multiplied the 3 by 75. If she had multiplied correctly, she would have obtained:

50x = 225

Step-by-step explanation:

We have to determine R and 8 such that(19) y(t) = Rcos (8V3t - 0) As we know, the solution of the given differential equation (1) is of the formu(t) = c1cos(8t√3) + c2sin(8t√3) Differentiating the given solution, we haveu'(t) = -8√3c1sin(8t√3) + 8√3c2cos(8t√3) Putting the initial conditions, we get 1/6 = c1

and -1 = -8√3c1 + 8√3c2On solving, we get

c1 = 1/6 and

c2 = 7/3√3

Therefore, the exact solution of the differential equation(1)\(u(t) = (1/6)cos(8t√3) + (7/3√3)sin(8t√3)\) The form of the solution of the differential equation (1) is \(y(t) = Rcos (8V3t - 0)\) Comparing the two equations, we get\(R = √(1/36 + 49/27) = 1/3√3 * √(4 + 49) = √53/9\) and 8 = tan^-1(7/3) Plot the exact solution together with the estimated solution obtained via the tangent line method for step sizes h = 0.02, 0.05, 0.1 in the interval [0, 1].Using the tangent line method, we have \(y(t+h) ≈ y(t) + h*y'(t)\) Therefore, the estimated solution obtained for h = 0.02,0.05,0.1 can be obtained by the following formulas:\(y(0.02) ≈ y(0) + 0.02*y'(0) y(0.05) ≈ y(0) + 0.05*y'(0)y(0.1) ≈ y(0) + 0.1*y'(0)\) Substituting the values of y(0) and y'(0), we get \(y(0.02) ≈ 1/6 - 0.02*8√3(7/3√3) ≈ -0.0701y(0.05) ≈ 1/6 - 0.05*8√3(7/3√3) ≈ -0.1461y(0.1) ≈ 1/6 - 0.1*8√3(7/3√3) ≈ -0.2893\) The estimated solutions are y(\(0.02) ≈ -0.0701y(0.05) ≈ -0.1461y(0.1) ≈ -0.2893\)

The function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1 and the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

To analyze the provided pseudo code for matrix multiplication and determine the function T(n) in terms of the number of operations, we need to examine the code and count the number of operations performed.

The pseudo code for matrix multiplication may look something like this:

```

MatrixMultiplication(A, B):

   n = size of matrix A

   C = empty matrix of size n x n

   for i = 1 to n do:

       for j = 1 to n do:

           sum = 0

           for k = 1 to n do:

               sum = sum + A[i][k] * B[k][j]

           C[i][j] = sum

   return C

```

Let's break down the number of operations step by step:

1. Assigning the size of matrix A to variable n: 1 operation

2. Initializing an empty matrix C of size n x n: n^2 operations (for creating n x n elements)

3. Outer loop: for i = 1 to n

- Incrementing i: n operations  

- Inner loop: for j = 1 to n

- Incrementing j: n^2 operations (since it is nested inside the outer loop)

- Initializing sum to 0: n^2 operations

- Innermost loop: for k = 1 to n

- Incrementing k: n^3 operations (since it is nested inside both the outer and inner loops)

- Performing the multiplication and addition: n^3 operations

- Assigning the result to C[i][j]: n^2 operations

- Assigning the value of sum to C[i][j]: n^2 operations

Total operations:

1 + n^2 + n + n^2 + n^3 + n^3 + n^2 + n^2 = 2n^3 + 3n^2 + 2n + 1

Therefore, the function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1

To determine the asymptotic (big O) complexity of the algorithm, we focus on the dominant term as n approaches infinity.

In this case, the dominant term is 2n^3. Hence, the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

The equation of the tangent plane to the surface y = x^2 - z^2 at the point (10, 36, 8) is 32x + 16z - y = 380.

To find the equation of the tangent plane to the surface y = x^2 - z^2 at the point (10, 36, 8), we need to find the gradient of the surface at that point. The gradient is a vector that points in the direction of the maximum rate of change of the surface, and its components are the partial derivatives of the surface with respect to x, y, and z.

Taking the partial derivatives of the surface with respect to x, y, and z, we get:

∂/∂x (y) = 2x

∂/∂y (y) = 1

∂/∂z (y) = -2z

Evaluating these partial derivatives at the point (10, 36, 8), we get:

∂/∂x (y) = 2(10) = 20

∂/∂y (y) = 1

∂/∂z (y) = -2(8) = -16

So the gradient at the point (10, 36, 8) is the vector:

grad(y) = (20, 1, -16)

This vector is perpendicular to the tangent plane at the point (10, 36, 8). We can use this fact and the point-normal form of the equation of a plane to find the equation of the tangent plane. The point-normal form is:

n · (r - r0) = 0

where n is the normal vector to the plane, r0 is a point on the plane, and r is any point on the plane.

Substituting the values we found earlier, we have:

(20, 1, -16) · ([x, y, z] - [10, 36, 8]) = 0

Simplifying this equation gives:

20(x - 10) + (y - 36) - 16(z - 8) = 0

which can be rearranged to:

32x + 16z - y = 380

Therefore, the equation of the tangent plane to the surface y = x^2 - z^2 at the point (10, 36, 8) is 32x + 16z - y = 380.

The unit normal vector to the surface f(x,y,z)=0 at the point p(2,5,-27) is (-1/sqrt(27), 5/sqrt(27), 1/sqrt(27))

To find a unit normal vector to the surface f(x, y, z) = ln(x - 5y - z) at the point P(2, 5, -27), you'll first need to compute the gradient of the function, which represents the normal vector.

The gradient is given by (∂f/∂x, ∂f/∂y, ∂f/∂z). Let's compute the partial derivatives:

∂f/∂x = 1/(x - 5y - z)

∂f/∂y = -5/(x - 5y - z)

∂f/∂z = -1/(x - 5y - z)

Now, evaluate the gradient at the point P(2, 5, -27):

∇f(P) = (1/(2 - 5*5 + 27), -5/(2 - 5*5 + 27), -1/(2 - 5*5 + 27))

∇f(P) = (1/-4, 5/4, 1/4)

Now we'll normalize this vector to get the unit normal vector:

||∇f(P)|| = sqrt\(((-1/4)^2\) + \((5/4)^2\) + \((1/4)^2)\) = sqrt(27/16)

Unit normal vector = ∇f(P)/||∇f(P)|| = (-1/4, 5/4, 1/4) / (sqrt(27/16))

Unit normal vector = (-1/sqrt(27), 5/sqrt(27), 1/sqrt(27))

To find the new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees, we can use the rotation formula:

x' = x * cos(theta) - y * sin(theta)

y' = x * sin(theta) + y * cos(theta)

Where (x, y) are the original coordinates, (x', y') are the new coordinates after rotation, and theta is the angle of rotation in radians.

Converting the angle of rotation from degrees to radians:

theta = 5 degrees * (pi/180) ≈ 0.08727 radians

Plugging in the values into the rotation formula:

The equation for a cosecant function with vertical asymptotes found at x = nπ such that n is an integer is `y = csc(x - nπ)`.

The cosecant function is the reciprocal of the sine function. The cosecant of a particular angle in a right triangle is the ratio of the hypotenuse to the side opposite the angle.

The cosecant function is written as follows: `csc(x) = 1/sin(x)`

Asymptotes are straight lines or curves that a graph approaches but never touches.

As a result, the graph of a curve gets closer and closer to the asymptote as it moves further away from the origin, but it never touches it.

For a function to have vertical asymptotes at `x = nπ`, the denominator of the function should equal zero. In the cosecant function, the denominator is equal to `sin(x - nπ)`.

Therefore, the vertical asymptotes are where `sin(x - nπ) = 0`.

The general form of the cosecant function is `y = A csc(B(x - C)) + D`.

The constants A, B, C, and D are used to alter the form of the graph of the cosecant function.

They can be used to alter the amplitude, period, phase shift, and vertical displacement of the graph, respectively.

42^2 = (18 + x)(18)

1,764 = 18(x + 18)

x + 18 = 98

x = 80

So the diameter of the reservoir is 80 meters.

The diameter of the reservoir shown above can be calculated based on the intersecting secant-tangent theorem as: 80 meters.

A diameter is a straight line segment that crosses the center of a circle thereby connecting two points on its circumference and it is twice the length of the radius of a circle.

To find the diameter (x), apply the intersecting secant-tangent theorem which states that:

AB² = AC(x + CA)

Substitute:

42² = 18(x + 18)

1,764 = 18x + 324
