On average shanth drinks 1/2 of a 6-ounce glass of water in 2/3 hour. How much water does she drink in an hour?.

Based on the definition of the geometric mean, the value of x is: 64.

The geometric mean of two numbers is the square root of the product of the two numbers.

In other words, if x and y are two numbers, the geometric mean of x and y is represented as √(xy).

If 16 is the geometric mean between 4 and x, then we have the following relationship:

√(4x) = 16

Squaring both sides:

4x = 256

Dividing both sides by 4:

x = 64

So the value of x is 64.

The function for this problem is given as follows:

P(x) = 125x - (40x + 1200).

In slope-intercept format, it is obtained as follows:

P(x) = 125x - 40x - 1200

P(x) = 85x - 1200.

Hence the slope is of 85, representing the rate of change, and option a is the correct option.

The graph shows the discontinuity of the function at x = -1 and x = 1. Therefore, the values of x at which the function is not continuous are -1 and 1.

The graph shows that at x = -1 and x = 1, the graph has a sharp jump in the value of the function. This means that the function is not continuous at those points, and thus the values of x at which the function is not continuous are -1 and 1. The graph represents a mathematical function, and the concept of continuity is crucial in mathematical analysis. A function is considered continuous at a specific point if the value of the function at that point exists and the limit of the function as the input approaches that point is equal to the value of the function at that point. In this particular graph, the function experiences a sharp increase or decrease in its value at the points x = -1 and x = 1. This sudden change in the function's value indicates that the function is not continuous at these points, meaning that its value does not approach a single limiting value as the input approaches these points. Thus, the points -1 and 1 are the values of x at which the function is not continuous.

For the differential equation dy/dx = (x - 2)e^-2y having initial condition y(2) = ln(2), the solution is e^2y = x² - 4x + 8.

What is differential equation?

Any equation with one or more terms and one or more derivatives of the dependent variable with respect to the independent variable is referred to as a differential equation.

The given differential equation is dy/dx = (x - 2)e^-2y.

The initial condition is y(2) = ln(2).

Then the integration of the equation will be -

1/(e^-2y) dy = (x - 2) dx

e^2y dy = (x - 2) dx

(e^2y)/2 = (x²/2) - 2x + C

The value of C at x = 2, y(2) = ln (2).

Then it is obtained that -

[e^(2 ln 2)]/2 = [(2)²/2] - 2(2) +C

e^(ln 2²)/2 = 4/2 - 4 + C

Simplifying the equation further -

2²/2 = (4 - 8)/2 + C

2 = -4/2 + C

C = 2 + 4/2

C = 4

Then the equation will be -

(e^2y)/2 = (x²/2) - 2x + C

(e^2y)/2 = (x²/2) - 2x + 4

e^2y = x² - 4x + 8

Therefore, the solution is e^2y = x² - 4x + 8.

Answer:

£4.80

Step-by-step explanation:

We know

A shop advertises 15% off

100% - 15% = 85%

So, £4.08 is the price at 85%

Find 1% by taking

4.08 divided by 85 = £0.048

Now find the price before the reduction by taking

0.048 times 100 = £4.80

So, it was £4.80 before the price reduction.

Time taken to complete 10.3 half lives is 10.3 × 122 s = 1257 s which is equal to for the number of 15 8 O nuclei in a given sample to decrease to a factor of 8 × 10⁻⁴of the initial value.

Now, According to the question:

Radioactive Decay:

The rate of decay of nuclei of a radioactive element is directly proportional to the number of radioactive nuclei present at that moment in the sample.

The equation which determines the disintegration of atoms is,

N = N₀ e⁻(λt)

where, N is the number of atoms undergoing decay

N₀ is the initial number of atoms present

λ is the rate constant

t is the time

For the number of 15 8 O nuclei in a given sample to decrease to a factor of 8 × 10⁻⁴ of the initial value, the number of half-lives decay took place be n which is given by,

2⁻ⁿ = 8 × 10⁻⁴

Taking log on both sides we have,

- n ln 2 = ln(8 × 10⁻⁴)

n = 10.3

Time taken to complete 10.3 half lives is 10.3 × 122 s = 1257 s which is equal to for the number of 15 8 O nuclei in a given sample to decrease to a factor of 8 × 10⁻⁴ of the initial value.

The original number was 4 is the correct answer.

Let's call the original number "x".

According to the problem, "a number is decreased by seven" which means x - 7.

And then, the new number is multiplied by 3 to get an answer of -9. That means (x - 7) * 3 = -9.

We can simplify the equation to 3x - 21 = -9 and then add 21 to both sides to isolate the variable: 3x = 12.

Finally, we can divide both sides by 3 to find x: x = 4.

Rounded to the nearest whole number, we would expect about 68 customers to pay with a credit card next week.

A whole number is a positive integer that does not have a fractional or decimal part. Whole numbers are the numbers we use for counting and for representing quantities that are not fractions or decimals. The set of whole numbers includes 0, 1, 2, 3, 4, 5, 6, and so on, with no limit on how high the numbers can go. Whole numbers do not include negative numbers or numbers with fractional or decimal parts.

To estimate the number of customers who will pay with a credit card next week, we can use the proportion of customers who paid with a credit card last week.

The total number of customers who paid with cash or a debit card is 77 + 27 = 104.

So the proportion of customers who paid with a credit card is 21/(104+21) = 0.1688 (rounded to four decimal places).

To estimate the number of customers who will pay with a credit card next week, we can multiply the expected total number of customers by this proportion:

0.1688 x 400 = 67.52

Rounded to the nearest whole number, we would expect about 68 customers to pay with a credit card next week.

The transitive closure by arithmetic operations on the adjacency matrix is  Compute A⁰ + A¹ + ... + A⁽ⁿ⁻¹⁾ where + is standard addition (integers)

The best method to determine the transitive closure by arithmetic operations on the adjacency matrix is C.

Compute

=> A⁰ + A¹ + ... + A⁽ⁿ⁻¹⁾

where + is standard addition (integers).

The standard addition of integers is used because we are counting the number of paths between each vertex.

In this method, we start by computing A⁰, which is simply the adjacency matrix itself.

A¹ gives us the number of paths between each vertex that are one step long. A² gives us the number of paths between each vertex that are two steps long, and so on. We continue this process until we have computed

If Sandra works for 42 hours per week and her weekly wage is £389.76, her hourly wage can be calculated as follows:

£389.76 / 42 hours = £9.28 per hour

When she receives a pay increase of 35p per hour, her hourly wage becomes:

£9.28 + 0.35 = £9.63 per hour

Her new weekly wage can then be calculated as:
