300,000 is the maximum number of bacteria the petri dish can hold

Given,

In a laboratory, the number of bacteria in a petri dish after t days is modeled by the function b (t) = Start fraction 300,000 over 1 999 e superscript negative 0.5 t baseline End fraction.

Which is equal to B (t) = 300,000/1+999e^-0.5t

We have to find that what does 300,000 represent;

Here,

B = Bacteria

t = Number of days

300,000 = Maximum number of bacteria the petri dish can hold

That is,

300,000 is the maximum number of bacteria the petri dish can hold

The statement is true. Roofs with a span of 40 feet or less and a pitch of ? or greater, as well as roofs with a span of more than 40 feet and a pitch of 1/4 or greater, are considered to be pitched.

In roofing terminology, the pitch refers to the steepness or slope of a roof. A pitched roof has a slope that allows water to drain efficiently. The pitch is typically measured as a ratio of vertical rise to horizontal span.

According to the statement, roofs with a span of 40 feet or less and a pitch of ? (undefined or not specified) or greater are considered to be pitched. This means that as long as the roof has a certain degree of slope or steepness, it is categorized as a pitched roof.

Similarly, roofs with a span of more than 40 feet and a pitch of 1/4 or greater are also considered to be pitched. In this case, the requirement for a minimum pitch of 1/4 (or a steeper slope) applies to roofs with a larger span.

The classification of roofs as pitched or not pitched depends on their span and the minimum pitch requirements specified. Roofs that meet the specified criteria for span and pitch are considered to be pitched roofs.

The subsets B. The 3×3 matrices with all zeros in the third row. C. The diagonal 3×3 matrices, and F. The symmetric 3×3 matrices are subspaces of M3(R).

A subspace of a vector space is a portion of that space that meets the three criteria of closure under addition, closure under scalar multiplication, and the presence of the zero vector. If two vectors from the subspace are added, the resultant vector will still be in the subspace because of closure under addition. If a vector from the subspace is multiplied by any scalar, the resultant vector will still be in the subspace, according to the concept of closure under scalar multiplication.

The conditions of a subspace are: closure under addition, closure under scalar multiplication, and contains the zero vector.

For all the options we have:

A: The 3 x 3 matrices in reduced row-echelon form (A): As this subset is not closed under addition, M3(R), it is not a subspace of M3(R).

B. The 3 x 3 matrices with all zeros in the third row: Due to its closure under addition and scalar multiplication as well as the presence of the zero vector, this subset is a subspace of M3(R).

C. The diagonal 3 x 3 matrices: This subset, which is closed under addition and scalar multiplication and contains the zero vector, is a subspace of M3(R).

D. The invertible 33 matrices: Because this subset is not closed under addition, M3(R), it is not a subspace of M3(R).

E. The 3 x 3 matrices that are not invertible Due to the fact that it is not closed under scalar multiplication, this subset is not a subspace of M3(R).

The equation of the circle graphed in this problem is given as follows:

(x - 4)² + (y - 3)² = 29.

The equation of a circle of center \((x_0, y_0)\) and radius r is given by:

\((x - x_0)^2 + (y - y_0)^2 = r^2\)

The radius of a circle represents the distance between the center of the circle and a point on the circumference of the circle.

The coordinates of the center are given as follows:

(4,3).

Hence:

(x - 4)² + (y - 3)² = r².

Considering the center of (4,3) and the point (-1, 1) on the circumference of the circle, the square of the radius is given as follows:

r² = (-1 - 4)² + (1 - 3)²

r² = 29.

According to the information provided, Jose's medically ideal weight is 250 pounds. Therefore, he would be considered to be obese when and if he weighed 300 pounds or more.

This means that the correct answer to the question is option b) 300.

It is important to note that obesity is typically defined as having a body mass index (BMI) of 30 or higher. BMI is calculated by dividing a person's weight in kilograms by their height in meters squared. A person's medically ideal weight is the weight that is considered healthy for their height and age.

BMI = (weight)/(maters squared)²

So, in summary, Jose would be considered to be obese when and if he weighed 300 pounds or more, as this would likely result in a BMI of 30 or higher, indicating obesity.

The distance between the opposite sides of the trampoline can be found to be 14. 42 yards

To find the distance between the opposite sides of the trampoline, we are essentially finding the diagonal length. We can use the Pythagorean theorem to do this by dividing the trampoline into two right triangles.

The distance between the opposite sides would then be:

c ² = a ² + b ²

c ² = 8 ² + 12 ²

c ² = 64 + 144

c ² = 208

c = √ 208

The ratio of John's money to Peter's money is 5/4. This means if John has a total amount of 5 then Peter will have a total of 4 as his amount.

Let's assume John has 'x' amount of  money, Peter has 'y' amount of money, The money John saved is 'p' and the money Peter saved is 'q'

So,

p = x - 80x/100                (equation 1)

q = y - 75y/100                (equation 2)

According to the given question, the amount John saved is equal to the amount Peter saved. Hence, we can equate equations 1 and 2.

p = q

x- 80x/100 = y - 75y/100

x - 0.8x = y - 0.75y

0.2x = 0.25y

x =  0.25y/0.2

x/y = 0.25/0.2

x/y = 25/20

x/y = 5/4

\(\sqrt[3]{2}+\sqrt[3]{4}\) is the root of the cubic polynomial  \(x^3-6 x-6\) .

A cubic function in mathematics is a function with the formula: f(x)=ax3+bx2+cx+d where the variable x has real values, the coefficients a, b, c, and d are complex integers, and a, a, and 0 are equal to zero. In other words, it is a real function as well as a polynomial function of degree three. The set of real numbers is specifically the domain and the codomain. All odd-degree polynomials have at least one real root, while cubic functions have one to three real roots (which may not be distinct).

A cubic function's graph always has one inflection point. It might have a local minimum and local maximum as its two essential points. A cubic function is monotonic if it is not.

Let  \(r=\sqrt[3]{2}+\sqrt[3]{4}\)

\(\text { Then, since }(a+b)^{\wedge} 3=a^{\wedge} 3+3 a^{\wedge} 2 b+3 a b^{\wedge} 2+b^{\wedge} 3=a^{\wedge} 3+3 a b *(a+b)+b^{\wedge} 3\)
