Answer: The width is 5

Step-by-step explanation:

The equation is x*(x-3)=40 solviing for x which is 8 but since width is x-3 then 8-3=5

Carbon 14 has a half-life of 5,600 years, which means that after 5,600 years, half of the initial amount of Carbon 14 will decay. Therefore, we can use the following formula to find the amount of Carbon 14 that was present 11,200 years ago:

A = A0 * (1/2)^(t/T)

where:

A0 = initial amount of Carbon 14

A = amount of Carbon 14 remaining after time t

t = time elapsed since the initial amount was present

T = half-life of Carbon 14

We know that the fossil contains 3 g of Carbon 14, which is the amount remaining after 11,200 years. We want to find the initial amount, A0.

Let's plug in the values we have into the formula and solve for A0:

3 g = A0 * (1/2)^(11,200/5,600)

3 g = A0 * (1/2)^2

3 g = A0 * 1/4

A0 = 4 * 3 g

A0 = 12 g

Therefore, the fossil contained 12 g of Carbon 14 11,200 years ago.

The sample that she must select if she wishes to be 99% confident that the population mean is within 10 minutes of the sample mean = 96

According to the question given,

We will be using the z-distribution to solve the following question.

The level of confidence she wishes to have = is 99%

The mean is within = 10 minutes.

The population standard deviation given is = 38 minutes.

The formula used for the z-distribution,

M = \(z\frac{\sigma }{\sqrt{n} }\) ------ equation 1

So given confidence is = 99%

\(\alpha\) = 0.99

Z = p-value of \(\frac{1+0.99}{2}\)

Z = 0.995

The critical value z will be given as,

z = 2.575

Now we have,

\(\sigma\) = 38

M = 10

Keeping these values in equation 1,

M = \(z\frac{\sigma }{\sqrt{n} }\)

10 = 2.575 x \(\frac{38}{\sqrt{n} }\)

10\(\sqrt{n}\) = 38 x 2.575

\(\sqrt{n}\) = 9.785

n = \((9.785)^{2}\)

n = 95.74

n = 96

Therefore, the sample that she must select if she wishes to be 99% confident that the population mean is within 10 minutes of the sample mean = 96

Internet Viewing A researcher wishes to estimate the average number of minutes per day a person spends on the Internet. How large a sample must she select if she wishes to be 99% confident that the population means is within 10 minutes of the sample mean?

Assume the population standard deviation is 38 minutes. Round your final answer up to the next whole number.

c = pi/2, and the value of c > 1 such that the average value of f(x) on the interval [2, 20] is equal to c is c = pi/2.

The average value of a function f(x) on the interval [a, b] is given by:

Avg = 1/(b-a) * ∫[a, b] f(x) dx

We want to find a value of c > 1 such that the average value of the function \(f(x) = (9pi/x^2)cos(pi/x)\) on the interval [2, 20] is equal to c.

First, we find the integral of f(x) on the interval [2, 20]:

\(∫[2, 20] (9pi/x^2)cos(pi/x) dx\)

We can use u-substitution with u = pi/x, which gives us:

-9pi * ∫[pi/20, pi/2] cos(u) du

Evaluating this integral gives us:

\(-9pi * sin(u) |_pi/20^pi/2 = 9pi\)

Therefore, the average value of f(x) on the interval [2, 20] is:

\(Avg = 1/(20-2) * ∫[2, 20] (9pi/x^2)cos(pi/x) dx\)

= 1/18 * 9pi

= pi/2

Now we set c = pi/2 and solve for x:

Avg = c

\(pi/2 = 1/(20-2) * ∫[2, 20] (9pi/x^2)cos(pi/x) dx\)

pi/2 = 1/18 * 9pi

pi/2 = pi/2

Therefore, c = pi/2, and the value of c > 1 such that the average value of f(x) on the interval [2, 20] is equal to c is c = pi/2.

The percent of the square shaded is 37.5 without including the % sign.

The square is divided into 4 equal parts

1/4 of the square is fully shaded

The other 1/4 is shaded half

Hence,

When the square is divided into 8 equal parts, 3 parts are shaded

Percent of square shaded= Parts shaded/ Total parts × 100

Answer:

The common continuous interval will be (0,∞).

Step-by-step explanation:

Given that,

The numerator = 12+√x

The denominator = √12+x

We know that,

For the numerator,

Any function under square root should be greater than and equal to the zero.

\(x\geq 0\)

So, the continuous interval is (0, ∞)

For the denominator,

\(\sqrt{12+x}>0\)

\(12+x>0\)

\(x>-12\)

The interval for the continuous and non zero function is,

(-12, ∞)

We need to calculate the continuous interval

Using given quotient

\(\dfrac{12+\sqrt{x}}{\sqrt{12+x}}\)

The continuous interval of numerator and  denominator are (0, ∞) and (-12, ∞).

Hence, The common continuous interval will be (0,∞).

Answer:

x = 8, y = 1

Step-by-step explanation:

11x - 20y = 28 ...(1)
3x + 4y = 36
or 15x + 20y = 180 ...(2)
Adding (1) and (2),
26x = 208
Or x = 8
Now, 3x + 4y = 36
3(8) + 4y = 36
4y = 36 - 32 = 4
so y = 1

To find the total number of scoops of ice cream served, we need to add the number of scoops of each flavor:

6 ¼ + 5 ¾ + 2 ¾

We can convert the mixed numbers to improper fractions to make the addition easier:

6 ¼ = 25/4

5 ¾ = 23/4

2 ¾ = 11/4

Now we can add:

25/4 + 23/4 + 11/4 = 59/4

So the ice cream parlor served 59/4 scoops of ice cream in total. We can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 1:

59/4 = 14 3/4

Therefore, the parlor served 14 3/4 scoops of ice cream in total.

As per the question statement, we are provided with a reference attachment, attached thereby,

And we are required to solve for "x", as per question no. 5 of the attachment.

To solve this question, first we need to know about the similarity of triangles.

Here, as per the similarity of triangles theorem, we can relate the question mentioned sides in the following equation:

[2(8x - 23) = (10x + 44)]

And solving the equation, we will be able to obtain the value of "x" which will be our desired answer, i.e.,

[2(8x - 23) = (10x + 44)]

Or, [(16x - 46) = (10x + 44)]

The first four terms of the sequence are:

a1 = 2

a2 = 2 - 3 = -1

a3 = -1 - 3 = -4

a4 = -4 - 3 = -7

The sequence defined by the rule an = 2, if n = 1; an-1-3, if n > 1, starts with the first term being 2. For all subsequent terms, the value of the previous term is subtracted by 3. Therefore, the second term of the sequence is -1 (2-3), the third term is -4 (-1-3) and fourth term is -7 (-4-3). This pattern of subtracting 3 from the previous term will continue for all subsequent terms in the sequence. The sequence can be represented by the function an = 2 - 3(n-1) for any natural number n.

When developing the Object Relational Model in the models.py file for a Django project, data types for each attribute must be specified is true statement.

The statement "When developing the Object Relational Model in the models.py file for a Django project, data types for each attribute must be specified" is true.

In Django, the models.py file defines the Object Relational Model (ORM) that maps the database tables to Python classes. Each attribute in the model represents a column in the corresponding database table. In order to define the attribute, you must specify the data type for the corresponding column.

Django supports several built-in data types for attributes, such as CharField, IntegerField, DateField, BooleanField, etc. You can also define custom data types by creating your own model fields.

By specifying the data type for each attribute, Django can ensure that the values entered into the database are of the correct type and can perform appropriate data validation. This is essential for maintaining data integrity and avoiding data-related errors.
