The function to represent the arithmetic sequence is y = 0.17x + 0.71, and an envelop weighing 8 ounces cost $2.07

An equation is an expression that shows the relationship between variables and numbers.

An arithmetic sequence is in the form:

[tex]a_n=a_1+(n-1)d\\\\where\ a_1=first\ term,d=common\ difference[/tex]

Let y represent the price to send an envelop of x ounces. The arithmetic sequence is:

y = a₁ + (x - 1)d

Given that the first ounce is 88 cents($0.88), hence a₁ = 0.88. Eadh additional ounce is 17 cents (0.17), hence d = 0.17. Therefore:

y = 0.88 + (x - 1)(0.17)

y = 0.17x + 0.71

For a cost of $2.07:

2.07 = 0.17x + 0.71

x = 8 ounces

The function to represent the arithmetic sequence is y = 0.17x + 0.71

f(x) = √x   ⇒   f(x) = -√(x -a) +b . . . . . . matches choice B

Function is the relationship between the input or domain and the output. A relation is a function if and only if there exists one value in the range for every domain value. A function is written as f x , where x is the input value. The general form of a function is y = f x

Function transformations

To move the domain from [0, ∞) to [a, ∞) requires the function be translated 'a' units to the right. That transformation is accomplished by replacing x with (x-a) in the function definition.

To move the range from [0, ∞) to [b, ∞) requires the function be translated upward by 'b' units. This is accomplished by adding 'b' to every function value.

Therefore, the range of the function will be (-∞,b] i.e. y ≤ b.

Hence, the required function is  f(x) = √x   ⇒   f(x) = - √(x -a) +b . . . . . . matches choice B

The process of quantity growth over time is called exponential growth. occurs when the rate at which a quantity changes instantaneously with time is proportionate to the quantity itself. A data pattern that shows bigger increases with time is known as exponential growth. Compound interest yields exponential rewards in the world of finance. Savings accounts with compound interest sometimes see exponential growth. characterized by an extremely fast exponential growth rate rise (in size or extent). exponentially.

The base of the exponentiation is the strongest indicator of whether an equation exhibits an exponential growth or decline.

It will be an exponential growth if the base is greater than 1.

It will be an exponential decay if the base is less than 1.

There won't be any exponential growth or decay if the function's exponent is zero.

Therefore: Decay exponential (base less than 1:

The results suggest that the lead concentrations in the medicine samples are relatively low, as all of the values are below 20 mg/g. However, it would be necessary to compare these values to a standard, such as the acceptable limit of lead in medicine set by a regulatory body, in order to determine if the medicine is considered safe.

The decimal values of the listed amounts suggest that the measurements were precise, as they are all reported to one decimal place. It means that the measurement was done with a precision of 0.1. In addition to that, the measurements are consistent and close to each other, which also indicates that the measurements were precise.

It's important to keep in mind that precision and accuracy are different things.

Solving a linear equation we can see that the tank will be filled in 12 minutes.

We know that the fish tank has a volume of 30 gallons, and it already has 24 gallons of wate on it.

Sara is adding more water at a rate of 0.5 gallons per minute, so after x minutes, the volume of water on the tank is modeled by the linear equation:

V(x) = 24gal + 0.5gal*x

The tank will be full when the volume is equal to 30 gallons, then we can solve the equation:

30 gal = 24 gal + 0.5gal*x

30 gal - 24gal = 0.5gal*x

Answer: x3 +y3 20

Step-by-step explanation:

The perimeter of Δ BUG with sides BG = 105, BU = 16 and UG = 30 is 151 units.

What is perimeter?

The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.

It is given that ΔTOP ~ ΔBUG.

The lengths of sides of ΔTOP is - TO = 16, TP = 20, OP = 30.

The length of one side of ΔBUG is BG = 105.

Since ΔTOP is same as ΔBUG, so sides BU and UG will same as sides TO and OP respectively.

So, BU = 16 and UG = 30.

The formula for the perimeter of a triangle is -

P = a + b + c

Where, P is the perimeter and a, b, c are the sides of the triangle.

For ΔBUG -

P = BU + BG + UG

P = 16 + 105 + 30

P = 151

Therefore, the perimeter of ΔBUG = 151 units.

A. The confidence interval estimate of the expected value of y will be wider than the prediction interval is correct.

A confidence interval gives an estimated range of a population parameter based on a sample. It is calculated by taking a sample of the population and using statistical methods to estimate the range in which the true population parameter would fall, with a certain level of confidence.

On the other hand, a prediction interval gives an estimated range of a future observation based on a sample. It is calculated by taking a sample of the population and using statistical methods to estimate the range in which a future observation would fall, with a certain level of confidence.

Since a prediction interval includes the uncertainty of an unobserved future value, it will typically be wider than the confidence interval estimate of the expected value of y which is based on the sample and the estimation of the population parameter.

Therefore Option A is the correct answer.

Answer:

To find the value of the quantity after 46 years, we can use the formula for continuous compound interest:

A = P(1 + r)^t

Where:

A = final amount

P = initial amount (4400)

r = rate of growth (0.5%)

t = number of years (46)

We need to convert the percentage rate to decimal form, so we divide the rate by 100

0.5/100 = 0.005

Now we can substitute the values into the formula:

A = 4400(1 + 0.005)^46

A = 4400(1.005)^46

A = 4400 * 1.294624

A = 5685.89

Therefore, the value of the quantity after 46 years is 5685.89, to the nearest hundredth.

Step-by-step explanation:

Therefore , the solution of the given problem of set A when A= {5, 6, 7, 8, ..., 35}.

In mathematics, a set is a logically arranged group of items that can be represented in either set-builder or roster form. Sets are typically denoted by curly brackets; for instance, A = 1, 2, 3, 4 is a set.

Here,

The set A contains integers between 5 and 35, inclusive. So, the cardinality of set A is the number of integers between 5 and 35, which is 35-5+1 = 31.

b. A when A= {xEZ: -2 ≤ x ≤ 90}.

The set A contains all integers between -2 and 90, inclusive. So, the cardinality of set A is the number of integers between -2 and 90, which is 90-(-2)+1 = 93.

c. An B| when A= {x EN: x ≤ 31} and B = {x EN: x is prime}

The set A contains all the natural numbers less than or equal to 31. The set B contains all the prime numbers less than or equal to 31. There are 15 prime numbers less than or equal to 31: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31. So, the cardinality of set B is 15.

Mathematically, the inverse is; [tex]f^{-1}(x) = \dfrac{2\cdot x + 1}{x - 1}[/tex]

The inverse of a function is another function that undoes the operations of another function, such that when the output of the function is the input of the inverse function, the input of the function is obtained.

The specified function is presented as follows;

f(x) = (x + 1)/(x - 2) and x ≠ 2

The inverse of the above function is found as follows;

Let y represent f(x);

y = (x + 1)/(x - 2)

x·y - 2·y = x + 1

x·y - x = 1 + 2·y

x·(y - 1) = 1 + 2·y

x = (1 + 2·y)/(y - 1) = (2·y + 1)/(y - 1)

Plugging in y = x, and x = f⁻¹(x), we get;
