The volume of a sphere with a radius of 7 cm (or diameter of 12 cm) is 904.32 cubic centimeters.

To find the volume of a sphere with a radius of 7 cm, we can use the formula:

V = (4/3) * π * r^3

where V represents the volume and r represents the radius. However, you mentioned that the diameter of the sphere is 12 cm, so we need to adjust the radius accordingly.

The diameter of a sphere is twice the radius, so the radius of this sphere is 12 cm / 2 = 6 cm. Now we can calculate the volume using the formula:

V = (4/3) * π * (6 cm)^3

V = (4/3) * 3.14 * (6 cm)^3

V = (4/3) * 3.14 * 216 cm^3

V = 904.32 cm^3

The missing angle measures in triangle ABC are 35.5° and 54.5°.

We know that,

In the right triangle ABC

∠A +∠B =90°   ( by complementary angles)

We find the measure of angle B.

we know that

\(tanB = \frac{opposite side angle B}{adjacent side angle B}\)

According to the question,

Opposite side angle B= 7 in

Adjacent side angle B = 5in

So, \(tanB = \frac{7}{5}\)

      \(B = arc tan(\frac{7}{5})\)

      B = 54.5°

Then, we find the measure of angle A

A + B = 90°

 A = 90°-B

A = 90° -  54.5° ( using subtraction)

A = 35.5°

The experimental probability of rolling a number less than 3 is 0.11 or 11% when rolling a 12-sided solid numbered from 1 to 12, based on the provided data.

The number of faces that are numbered less than 3 on a 12-sided solid is 2, i.e., 1 and 2. Therefore, the probability of rolling a number less than 3 can be calculated by adding the frequencies of rolls that resulted in 1 and 2, and then dividing the sum by the total number of rolls.

From the table, we can see that the frequency of rolling a 1 is 10 and the frequency of rolling a 2 is 12. Therefore, the total frequency of rolling a number less than 3 is 10 + 12 = 22.

The total number of rolls is 200.

The experimental probability of rolling a number less than 3 is the frequency of rolling a number less than 3 divided by the total number of rolls:

Experimental probability = Frequency of rolling a number less than 3 / Total number of rolls

Experimental probability = 22 / 200

Positive value of a vertically stretches the graph of f when a > 1 or shrinks the graph of f when a < 1. h translates the graph of f to the left when h < 0 or right when h > 0.

Several real-world scenarios use exponential functions, including population increase, compound interest, radioactive decay, and the spread of diseases. For instance, an exponential function may be used to simulate the expansion of a bacterial population, with the rate of increase being proportional to the population size. Similarly, compound interest, which applies the rate of interest to the principal sum across a number of periods, can be represented by an exponential function.

Positive value of a vertically stretches the graph of f when a > 1 or shrinks the graph of f when a < 1. h translates the graph of f to the left when h < 0 or right when h > 0 and k translates the graph of f up when k > 0 and down when k < 0.

The rancher has 5,280 acres left after selling off 5 quarter sections.

There are different ways to approach this problem, but one possible method is to convert all the sections and subsections to acres and then subtract the number of acres sold.

One section is equal to 640 acres (1 mile x 1 mile)

One-half section is equal to 320 acres (1/2 mile x 1 mile)

The one-quarter section is equal to 160 acres (1/2 mile x 1/2 mile)

The rancher owns:

8 full sections x 640 acres/section = 5,120 acres

3 half sections x 320 acres/half section = 960 acres

Total = 6,080 acres

The rancher sells off:

5 quarter sections x 160 acres/quarter section = 800 acres

The number of acres left is:

6,080 acres - 800 acres = 5,280 acres

Therefore, the rancher has 5,280 acres left after selling off 5 quarter sections.

The factor that provides the basis for the grading of newly diagnosed malignant tumours is degree of differentiation.

The level of differentiation impacts an individual's capacity to control their emotions, thoughts, individuality, and connections to others. The degree of any differential equation can be obtained when it is expressed as a polynomial; otherwise, the degree cannot be defined.

The mechanisms by which immature cells develop into mature cells with particular roles are described in biology. This indicates the degree to which tumour tissue resembles the healthy tissue from which it originated in the context of cancer. Compared to poorly or undifferentiated cancer cells, well-differentiated cancer cells resemble normal cells more and grow and spread more slowly.

Answer:

(2, 3) and (-2, 11).

Step-by-step explanation:

To solve this system of equations, we can set both equations equal to each other:

x² -2x + 3 = -2x + 7

Combine like terms:

x² -4 = 0

Factor using difference of squares:

(x - 2)(x + 2) = 0

Therefore, x = 2 and -2. Plug both of these into an equation to solve for the 'y' value:

f(x) = -2(2) + 7

f(x) = -4 + 7

f(x) = 3

------------------

f(x) = -2(-2) + 7

f(x) = 4 + 7

f(x) = 11

Therefore, the two ordered pairs are (2, 3) and (-2, 11).

The time taken by both to mow the lawn is 36 minutes.

This is a question of time and work.

Time taken by girl to mow the loan = 60 minutes.

We have to find the time taken by both of them together to mow the lawn.

LCM(60,90) = 180

Let the total work to be done to mow the lawn be 180 units.

Hence,

Efficiency of boy = 180/90 = 2 units

Step-by-step explanation:

If you were to plot the given points, you would quickly see that this is a vertical line where x = 4 (a visual is always a good place to start).  

Vertical lines have a slope that is undefined and are written in the form of x = .

If you had plugged into the slope formula \(m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }\) , where (\(x_{1}, y_{1}\)) is (4, 8) and (\(x_{2}, y_{2}\)) is (4,6) the result would be as follows:

\(m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }\)

    = \(\frac{6 - 8}{4 - 4}\)

    = \(\frac{-2}{0}\)

Because you can not divide by 0, the slope is in fact undefined.

Matrix-vector multiplication is a linear operation because it satisfies the properties of scalar multiplication and vector addition, which are a(u+v) = au + av and a(cu) = cau, where a is a scalar and u and v are vectors.

Matrix-vector multiplication is a fundamental operation in linear algebra, where a matrix is multiplied by a vector to produce another vector. This operation is considered linear because it adheres to certain properties.

The first property is scalar multiplication, which states that multiplying a vector u by a scalar a and adding it to another vector v (a(u+v)) is equivalent to multiplying u by a (au) and v by a (av) separately and then adding the results (au + av). In other words, the operation distributes over vector addition.

The second property is the distributive property of scalar multiplication, which states that multiplying a vector u by a scalar c and then multiplying the resulting vector (cu) by another scalar a is equivalent to multiplying u by the product of the two scalars (cau). This property allows the scalar multiplication to be distributed over scalar multiplication.

These properties ensure that matrix-vector multiplication preserves the linearity of the underlying vector space. They enable the manipulation and analysis of systems of linear equations, transformations, and other mathematical operations involving matrices and vectors.
