Step-by-step explanation:

correct on edge

The method that describes an experiment is B) Method B is an experiment because the students are randomly assigned a font.

This refers to the scientific procedure that is undertaken in order to make a discovery or prove a theorem.

Hence, there are two methods available for use for students who are randomly assigned fonts Method A has to do with the intentional selection, and Method B has to do with random selection.

As a result of this, we can state that Method B is an experiment because the students are randomly assigned a font.

Step-by-step explanation:

As ratio is not given, we cannot prove that they are scaled copy.

Corresponding portions, or parts that are at the same location in relation to the remainder of each figure, exist in both the original figure and its scaled copy. These components could be angles, points, or segments. Polygon 2, for instance, is a scaled-down version of Polygon 1. There is a point in Polygon 2 for each point in Polygon 1.

Given,

Polygon ZSCH is a Scaled copy of Polygon XJYN.

We simply calculate the ratio of the lengths of the two corresponding sides of two polygons to determine the scale factor. The scaling factor is known as such and the polygons are similar if the ratio is the same for all matching sides.

As ratio is not given, we cannot prove that they are scaled copy.

All tables that represent proportional relationship between x and y are:

B. table B.

E. table E.

In Mathematics and Geometry, a proportional relationship is a type of relationship that produces equivalent ratios and it can be modeled or represented by the following mathematical equation:

y = kx

Where:

Next, we would determine the constant of proportionality (k) by using various data points as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = (20 - 15)/(10 - 5) = (5 - 4)/(1 - 0)

Constant of proportionality, k = 1.

Therefore, the required linear equation is given by;

y = kx

y = x

The length of the image of the line, after being dilated by the scale factor, would be B. 12 units.

To find the length of the image of the line after dilation, we need to calculate the distance between the two points on the dilated line.

The dilated line's points will be (3, 4 x 3) and (3, 8 x 3), which simplify to (3, 12) and (3, 24).

Then find the distance using the distance formula :

= √((x2 - x1) ² + (y2 - y1) ²)

= √((3 - 3) ² + (24 - 12) ²)

= √ (0 + 144)

Corresponding angles are those that are located on the same side of the transversal and in identical relative positions to the parallel lines. Angles that correspond to one another have the same measure.

Alternate interior angles are those that are located on the transverse and within the area between the parallel lines, respectively. Congruent alternate interior angles exist.

Alternate external angles are those that are outside of the space between the parallel lines and on the opposing sides of the transversal. Congruent external angles exist between the two.

In this case, the rate of change is constant as each new pair of values in the table increases by double the previous pair of values.

A) All x- and y-intercepts include the following:

x-intercepts: none.

B) The equation for vertical asymptote is x = 4 and the equation for horizontal asymptote is y = 0.

C) The domain and range of f are:

Domain = [-∞, 4) U [4, ∞]

Range = [0, ∞]

In Mathematics, the x-intercept is the point at which the graph of a function crosses or touches the x-coordinate and the y-value or value of "y" is equal to zero (0).

Part A.

Based on the graph of this rational function, the x-intercept and y-intercept include the following:

x-intercept: none.

y-intercept: 1.

Part B.

An equation that represents the vertical asymptote is x = 4 while the equation represents the horizontal asymptote is y = 0 because the line does not cross those points.

Part C.

By critically observing the graph of this rational function, we can logically deduce the following domain and range:

Domain = [-∞, 4) U [4, ∞] or {x|x ≠ 4}.

Range = [0, ∞] or {y|y ≥ 0}.

Considering the continuity concept, f(x) is discontinuous at x = -4.

A function f(x) is continuous at x = a if it is defined at x = a, and the lateral limits are equal, that is:

\(\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)\)

At x = -4, we have that:

As the lateral limits are different, the limit is not defined, and thus f(x) is discontinuous at x = -4.

the perimeter is the sum of the 3 sides.

subtract the sum of the 2 given sides from the perimeter for missing side, that is

10x - 6 - (x + 1 + 3x - 2)

= 10x - 6 - (4x - 1 ) ← distribute parenthesis by - 1

The original price of the play station is $620.

Given that, the cost of the play station=$558 and discount=10%.

We need to find the original price of the play station.

The definition of discount is reduced prices or something being sold at a price lower than that item is normally sold for.

Let the original price be x.

Now, x-10% of x=558

⇒x-0.1x=558

⇒0.9x=558

⇒x=$620

Therefore, the original price of the play station is $620.

Step-by-step explanation:

It would take them approximately 6.24 hours (or 6 hours and 14 minutes) to complete the order if they work together.

To solve this problem, we can use the formula:

Time = Work ÷ Rate

Time is the time it takes to complete the job, Work is the amount of work to be done, and Rate is the rate of work.

Let's assume that the amount of work to be done is 1 (it doesn't matter what unit we use as long as we are consistent).

Then, Maria's rate of work is 1/12 (she can do 1 job in 12 hours) and the new clerk's rate of work is 1/13 (he can do 1 job in 13 hours).

If they work together, their combined rate of work is the sum of their individual rates:

Rate = Maria's rate + New clerk's rate

Rate = 1/12 + 1/13

Rate = (13 + 12) / (12 x 13)

Rate = 25 / 156

So, their combined rate of work is 25/156 jobs per hour.

Now, we can use the formula to find the time it takes for them to complete the job together:

Time = Work ÷ Rate

Time = 1 ÷ (25/156)

Time = 156/25

Answer:

452.16 mm squared is a correct answer.

Sure!

;):);):):):):):):):)

Answer:

Step-by-step explanation:

Given function is,

f(x) = \(x\sqrt{x}\)

We can rewrite this function as,

f(x) = \(x^{\frac{3}{2}}\)

a). Domain of the function is [0, ∞)

Derivative of the function in this domain,

f'(x) = \(\frac{3}{2}x^{(\frac{3}{2}-1)}\)

     = \(\frac{3}{2}x^{\frac{1}{2}}\)

Since, f'(x) > 0 in the interval [0, ∞)

Function is increasing in the interval [0, ∞)

b). For local maxima and local minima,

  Second derivative of the function,

  f"(x) = \(\frac{3}{2}(\frac{1}{2})x^{\frac{1}{2}-1}\)

         = \(\frac{3}{4}x^{-\frac{1}{2}}\)  > 0

   So the function should have a local minima.

   But the function is continuous in the interval x ≥ 0,

   There is no local minima (only absolute minima).

c). Since, second derivative is undefined at x = 0,

   There are no inflection points.

d). Since, f"(x) > 0 in the interval [0, ∞)

   Concavity of the curve is UPWARDS.
