Answer:

Option B

Increases

Step-by-step explanation:

to solve this problem, let us plug in figures to replace the variables in the equation.

Let y be equals to the rational exponent which represents the cube root of x^m,

The equation is given as y =[tex]\sqrt[3]{x^{m}}[/tex]

let x= 3

and m =, 3, 4, and  5

when m = 3, we have [tex]y =\sqrt[3]{3^{3}} =3[/tex]

when m = 4, we have [tex]y =\sqrt[3]{3^{4}} =4.33[/tex]

when m = 5, we have [tex]y =\sqrt[3]{3^{5}} =6.24[/tex]

As we can see, the values of y are increasing. Hence,  we can say that the value of the rational exponent increases as y increases

Final answer:

As the positive integer m increases in the rational exponent expression for the cube root of [tex]x^m[/tex], the rational exponent itself increases. This is because the base x is being raised to a higher power, exemplified by [tex]x^{2/3[/tex] compared to [tex]x^{3/3[/tex], showing an increase in expression value.

Explanation:

If a rational exponent represents the cube root of [tex]x^m[/tex], where m is a positive integer, the form used to represent this is [tex]x^{m/3[/tex]. As m increases, the value of the expression increases because the base (x) is being raised to a higher power. Therefore, the correct answer to how the rational exponent changes as m increases is it increases.

For example, consider x to equal 8, and compare [tex]x^{2/3[/tex] (the cube root of 8 squared) to [tex]x^{3/3[/tex] (the cube root of 8 cubed).

As m increases from 2 to 3, the exponent changes from 2/3 to 3/3 (or 1), and thus the result of the expression goes from 4 to 8, illustrating that the expression's value increases with m.

Answer:

30 slices

Step-by-step explanation:

Make a proportion

You ate 5 out 20 slices, and x out of 120 slices

5/20=x/120

Multiply both sides by 120 to get x by itself

120(5/20)=(x/120)120

The 120s on the right will cancel out, and we are left with

30=x

So, you would eat 30 slices of pizza out of 120 slices

Answer:

5/18, 0.278, 27.8%

Step-by-step explanation:

In this problem, we basically want to find the probability that Marcus will have a total sum of the 2 dices less than Lucia.

In her throw, Lucia gets a 4 and a 1, so she gets a total sum of 5.

Therefore, we want to find the probability that Marcus will get 5 or less.

The possible combinations that can be obtained when throwing 2 dices are 36 (6 x 6).

Of all these 36 combinations, those that gives a sum of 5 or less are:

1 +1 = 2

1 + 2 = 3

2 + 1 = 3

1 +3 = 4

3 + 1 = 4

1 + 4 = 5

4 + 1 = 5

2 + 2 = 4

2 + 3 = 5

3 + 2 = 5

So, a total of 10 combinations.

Since the probability of an event is:

[tex]p(A)=\frac{s}{n}[/tex]

where

s is the number of successfull outcomes

n is the number of total possible outcomes

Here we have

s = 10

n = 36

Therefore the probability here is

[tex]p=\frac{10}{36}=\frac{5}{18}=0.278 = 27.8\%[/tex]

Given:

Given that the graph of the regression model.

We need to determine the type of the best - fitting regression model.

Model of the graph:

From the graph, it is obvious that the points in the graph does not follows a straight line and thus the graph is not a linear model.

Also, from the graph, we can see that the points in the graph follows a curve pattern.

This curve pattern in the graph indicates that the graph follows an exponential curve.

Therefore, the best - fitting regression model for the given data plot is exponential model.

Hence, Option C is the correct answer.

Hope i could help! :D

Step-by-step explanation:

By the 1993 season, the Miami Dolphins had appeared on Monday Night Football 46 times.

To solve this question, we are given that the San Francisco 49ers had appeared on Monday Night Football 35 times by the 1993 season. We are also informed that the Miami Dolphins had made 11 more appearances than the 49ers. Therefore, to find the total number of times that the Miami Dolphins had appeared, we simply need to add 11 to the 49ers' appearances.

So, 35 (49ers' appearances) + 11 (additional Dolphins' appearances) = 46.

This means that by the 1993 season, the Miami Dolphins had appeared on Monday Night Football a total of 46 times.

Answer:

True

Step-by-step explanation:

Final answer:

The statement is True: the locus of points concept is used in geometry to define shapes based on the equality of distances, such as an equidistant curve from a line, or a circle at a fixed distance from a point.

Explanation:

The statement "The locus of points idea allows you to define geometric objects just by determining whether or not two distances are equal" is True. The locus of points is a concept in geometry that represents a set of points that satisfy certain conditions. For instance, the locus of points at a given distance from a straight line is known as an equidistant curve, and when this distance is from a point, it forms a circle. Euclidean geometry often assumes that distances are consistent and measurable, idealizing the real world where we use rules and compasses to define distances and constructs. Concepts like parallelism and measurement systems, as found in axioms, help to build an understanding of geometric relations on lines. Moreover, the validity of geometric propositions can be questioned in real-world applications as geometry serves as an abstraction of physical space.

Answer:

Step-by-step explanation:

Answer:

w=1

Step-by-step explanation:

QT=(RS+PU)/2

4w+27=(2w+21+w+38)/2

3w+59=2*(4w+27)=8w+54

8w-3w=59-54

5w=5

w=1

Final answer:

After setting up an equation for the average, we calculated that the value of w is 5.

Explanation:

The question involves solving for a variable w in the context of a trapezoid and its midsegment.

We know that a midsegment of a trapezoid is parallel to the bases and its length is the average of the lengths of the two bases.

Given RS=2w+21, QT=4w+27 (midsegment), and PU=w+38, we set up the equation (2w+21 + w+38)/2 = 4w+27, since the length of the midsegment QT is the average of the lengths of the bases RS and PU.

Simplifying this equation:

Therefore, the value of w is 5.

Step-by-step explanation:

That means she type 450/6 minutes. Take 450 and divide it by 6.

450/6 = 75

Answer:

- 1

Step-by-step explanation:

The average rate of change in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [4, 7 ], thus

f(b) = f(7) = 7² - 4(7) - 1 = 49 - 28 - 1 = 20

f(a) = f(- 4) = (- 4)² - 4(- 4) - 1 = 16 + 16 - 1 = 31

average rate of change = [tex]\frac{20-31}{7+4}[/tex] = [tex]\frac{-11}{11}[/tex] = - 1

Answer:

Mean: 4

Median: 3

Mode: 1

Step-by-step explanation: For the mean, you have to add all the numbers and divide it by the amount of numbers there are to find the average (mean). For the median, you have to order the numbers from least to greatest and since there are 9 numbers and 9 is an odd number, you have to see which number is in the middle, 3 was in the middle for this problem. The mode is which number repeats the most, which was 1.  

Answer:

Mean = 4, Median = 3, Mode = 1

Step-by-step explanation:

The mean is also the average. To find it you add all the numbers up and divide that by the # of numbers given.

[tex]\frac{3+5+1+5+1+1+2+3+1+5}{7} =\frac{28}{7}=4[/tex]

Median is the middle number when all the numbers are written out numerically including the doubles

1 1 1 2 3 3 5 5 15

Mode is the number that appears the most

in this case it is 1

2. add 3/7 and -3/8 you get a long decimal so it's irrational

Answer:

= -2

Step-by-step explanation:

F(f^-1(x)) = x   so in the case of yur question the -2 is in the place of the x in  the explanation

The value of [tex]f^{-1}[/tex](-2) is -4 , f(-4) is -2 and f[ [tex]f^{-1}[/tex](-2)] is also -2.

The inverse of a function is basically a reverse function or undo of the function.

For example y = f(x) then inverse will be x = f(y).

It means in the inverse function we need to interchange x and y.

Another example y = 3x² ⇒ x = √(y/3) will be the inverse.

Given the function,

f(x) = 1/2x and  [tex]f^{-1}[/tex](x)= 2x

Now,

[tex]f^{-1}[/tex](-2) = 2(-2) = -4

f(-4) = 1/2 (-4) = -2

Now,

Operation of f is that it will come x variable down,

So,

f[ [tex]f^{-1}[/tex](-2)] = f(-4)

f(-4) = -2

Hence "The value of [tex]f^{-1}[/tex](-2) is -4 , f(-4) is -2 and f[ [tex]f^{-1}[/tex](-2)] is also -2".

Car A consumes 25 gallon and car B consumes 15 gallon.

Step-by-step explanation:

Given,

The fuel efficiency of car A = 20 miles per gallon.

The fuel efficiency of car B = 15 miles per gallon.

In a week, two cars went 725 miles and consumed 40 gallons.

To find the consumption of each car in that week.

Let,

Car A consumed x gallon

Car B consumed y gallon.

According to the problem,

x+y = 40 ----- (1)

20x+15y = 725

or, 4x+3y = 145 -------- (2)

From (1) we get, x = 40-y

Putting the value of x in (2) we get,

4(40-y)+3y = 145

or, 160-4y+3y = 145

or, -y = 145-160

or, y = 15

From (1) we get, x = 40-15 = 25

Hence,

Car A consumes 25 gallon and car B consumes 15 gallon.
