The range of the function is {0.16, 0.4, 1, 2.5, 6.25}. With an increase in the value of the domain, the range of the function is increasing.

What is a function?

A function from a set X to a set Y allocates exactly one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain.

The given function is

f(x) = 2.5^x.

Given domain is {-2, -1, 0, 1, 2}.

Now putting x = -2, -1, 0, 1, 2 in the function f(x) = 2.5^x.

When x = -2:

f(-2) = 2.5^(-2)

f(-2) = 0.16.

When x = -1:

f(-1) = 2.5^(-1)

f(-1) = 0.4

When x = 0:

f(0) = 2.5^(0)

f(0) = 1.

When x = 1:

f(1) = 2.5^(1)

f(1) = 2.5

When x = 2:

f(2) = 2.5^(2)

f(2) = 6.25

The range of the function is {0.16, 0.4, 1, 2.5, 6.25}

The values of the range increase with the increase of domain.

Answer:

<PQS = 47

<SQR = 43

Step-by-step explanation:

A right angle equals 90°.

7x + 145 + 6x + 127 = 90  Combine like terms

13x + 272 = 90  Subtract 272 from both sides

13x = 90 - 272

13x = -182  Divide both sides by 13

x = -14

Substitute -14 for x

<PQS

7x + 145

7(-14) + 145

-98 + 145

47

<SQR

6x + 127

6(-14) + 127

43

43 + 47 = 90

The function f(x) = x² - 2x - 3 / x² + 3x + 2 have holes at coordinate (-1, -4)

Function holes are areas of a function that are not defined. They can be caused by a lack of data, a lack of understanding of the problem, or a lack of knowledge of the domain. Function holes can lead to errors in the output of a function, as the function will not be able to produce a result for the undefined area. A hole is a location on the graph where the function's value is not known. When a rational function is simplified, its numerator and denominator will cancel if they have a common factor. The cancelled value creates a hole in the graph.

In the given question, we need to plot the function on a graph to determine it's holes.

Answer:

The sample size needed to guarantee a margin of error of at most 0.08 in a 95 percent confidence interval for an unknown population proportion p can be found using the formula:

n = (p(1-p)) / E^2

Where n is the sample size, p is the sample proportion, E is the margin of error, and Z is the Z-score for the desired level of confidence. Since we are using a 95 percent confidence level, the Z-score is approximately 1.96.

To find the smallest sample size that will guarantee a margin of error of at most 0.08, we need to plug in the values for E and Z into the formula and solve for n.

n = (p(1-p)) / (0.08)^2

Since we don't know the population proportion p, we can use a rough estimate of 0.5 to get a rough estimate of the sample size. This is known as the conservative sample size, because it is based on the worst-case scenario (i.e. the proportion is exactly 0.5).

n = (0.5 * (1 - 0.5)) / (0.08)^2

n = (0.25) / (0.0064)

n = 3906.25

So, the smallest sample size that will guarantee a margin of error of at most 0.08 is 3906.25.

It should be rounded up to 3907.

On solving the provided question, we can say that we have the equations as  y = 3x - 7 where x > 0. so let us assume x = 4 = > y = 5

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

The value of x in the given linear equation 4x - 3 - 5x = 24 is:

x = 27

Here we want to find the value of x in the equation:

4x - 3 - 5x = 24

Notice that this is a linear equation that depends on x.

To find the solution, we need to isolate x in one of the sides of the linear equation.

First, we need to group like terms so we get:

4x - 3 - 5x = 24

(4x - 5x) - 3 = 24

-x - 3  = 24

Now we can move the "-3" to the other side to get:

-x = 24 + 3

-x = 27

And now change the sign:

x = -27

The measure of angle RSN is obtained as follows:

m < RSN = 31º.

First we must consider that the sum of the measures of the internal angles of a triangle is of 180º.

The internal angles of triangle RST, along with their measures, are given as follows:

The sum of these three measures is of 180º, hence the value of x is obtained as follows:

3x + 17 + 8x - 32 + 2x = 180

13x = 195

x = 195/13

x = 15.

Then the measure of angle RST is given as follows:

m < RST = 3(15) + 17

m < RST = 62º.

Angle RSN is a bisection of the angle RST, meaning that it has the measure half that of RST, hence:

m < RSN = 0.5 m < RST

m < RSN = 0.5 x 62

m < RSN = 31º.

What is function ?

Function can be defined in which it relates an input the output.

Given functions ,

f(x) = 3x^2 - 4x + 1 and g(x) = x-6

(f+g) (x)  =  3x^2 - 4x + 1 + x-6

(f+g) (x) = 3x^2 - 3x - 5

(f+g)(0) = 3(0) - 3(0) - 5

(f+g)(0) = -5

(f-g) x  = 3x^2 - 4x + 1 -( x-6)

(f-g)x = 3x^2 - 5x +7

(f-g)(0) = 3(0)-5(0) + 7

(f-g) (0) = 7

(fg)(x) = (3x^2 - 4x + 1) *( x-6)

(fg) (x) = 3x^3 - 4x^2 + x -18x^2+24x -6

Using probability, Laila's expected winnings are $126.67.

The study of probability mathematics deals with the topic of a random event. A coin, for instance, could land on its Head or Tail if it were thrown into the air.

Finding the likelihood for each and every conceivable value, and then adding them all together, yields the expected value.

We must determine the likelihood and value of each conceivable outcome.

Laila chances of selecting three consecutive red markers are: (6/10)(5/9)(4/8) = 1/6

Laila's initial marker's likelihood of being red but not picking three straight red markers is 6/10 - 1/6 = 13/30.

Any other event has a probability of 1 - 1/6 - 13/30 = 2/5.

We can now write our expected value expression:

Step-by-step explanation:

Answer: The range of a function is the set of all possible output values (y-values) for a given function.

For the function y = 3/x+8, we can find the range by analyzing the domain of the function. The domain of a function is the set of all input values (x-values) for which the function produces a valid output value.

The range of this function is all real numbers, since the denominator x+8 can't be equal to zero.

However, we can't express the range of the function as a specific set of numbers because the range is defined as all real numbers. The answer would be R

It's worth noting that if we change the function for example to y = 3/x-8, the domain would be x≠8 and the range would be y<-8/3

3x - y = 7

= 3x - y - 7 = 0

= 3x - 7 = y — (equation i)

Substitute (equation i) into the second equation:

3x + (3x - 7) = 11

Expand the brackets by applying the Distributive Law and bring all the like terms together:

3x + 3x - 7 = 11

= 6x - 7 = 11

= 6x = 11 + 7

= 6x = 18

= x = [tex]\frac{18}{6}[/tex]

= x = 3

Substitute the calculated value of x into (equation i) to determine the value of y:

3 x - 7 = y

The length of an ellipse's boundary is its perimeter. It is sometimes referred to as the ellipse's circumference (recall that perimeter is also known as the circumference for the curved shapes). The orbits of the planets in our solar system, as well as 2D illustrations of objects like eggs and watermelons, are some instances of ellipses in nature. The collection of all points whose distance from two fixed points (referred to as foci) is always constant is known mathematically as an ellipse.

The circumference of the ellipse can be calculated using one of three approximate formulas. When the ellipse is nearly circular, or when the values of a and b are roughly equal, the first one is employed. When one of the values of "a" and "b" is noticeably larger than the other value, the second (or third) formulas are employed.

We can use either formula 2 or 3 to determine the perimeter when the values of "a" and "b" are not exactly identical. Formula 3 provides a value that is smaller than the actual value, but formula 2 provides a bigger value. By averaging the results from formulas 2 and 3, we can therefore reach a result that is reasonably close.
