What is the range of the function gx x 12 2?

Answers

Answer 1

The function is given by g(x)= | x-12| -2 then , range is given by

{y| y> -2 } that is  the range would be the all y values greater than or equal to -2

It is an absolute value function which has a v- shaped graph.

The vertex form of an absolute function is given by y = a|x-h| +k, where (h,k) is the vertex.

Comparing the given equation with this, we have

h = 12

Answers

The age of the decaying sample according to the decay formula is 42,009 years.

The rate of radioactive carbon-14 decay depends on the function

\(A(t) = A_{0} e^{-0.0001216t}\)

where \(A_{0}\) is the quantity found in living plants and animals, t is in years, and is the age.

60% of the carbon-14 of a current-day sample was present in a sample taken from a refuse deposit close to the Strait of Magellan. We need to evaluate the age of the sample,

A = 60 % of \(A_{0}\) = (3/5)\(A_{0}\)

Putting this in the decay equation, we have,

\(\frac{3}{5} A_{0} = A_{0} e^{-0.0001216t}\\\\ 0.6= e^{-0.0001216t}\\ \\ln0.6 = -0.00001216t\\\\-0.51082 = -0.00001216t\\\\t = 42,008.68\)

Digit thinks that the graphs of exponential and logarithmic functions are more alike than they are different.

What do you think he means by that?

Be sure to express your thoughts clearly and use correct mathematical language in your explanation.

Answers

Answer:

Definitions

At the most basic level, an exponential function is a function in which the variable appears in the exponent. The most basic exponential function is a function of the form y=bx where b is a positive number.

When b>1 the function grows in a manner that is proportional to its original value. This is called exponential growth.

When 0>b>1 the function decays in a manner that is proportional to its original value. This is called exponential decay.

Graphing an Exponential Function

Example 1

Let us consider the function y=2x when b>1. One way to graph this function is to choose values for x and substitute these into the equation to generate values for y. Doing so we may obtain the following points:

(−2,14), (−1,12), (0,1), (1,2) and (2,4)

As you connect the points, you will notice a smooth curve that crosses the y-axis at the point (0,1) and is increasing as x takes on larger and larger values. That is, the curve approaches infinity as x approaches infinity. As x takes on smaller and smaller values the curve gets closer and closer to the x-axis. That is, the curve approaches zero as x approaches negative infinity making the x-axis is a horizontal asymptote of the function. The point (1,b) is on the graph. This is true of the graph of all exponential functions of the form y=bx for x>1.

solve the following recurrence relations:
a) an=an-1+3(n-1), a0=1
b) an=an-1+n(n-1), a0=3
c) an=an-1+3n^2, a0=10

Answers

a) To solve the recurrence relation an = an-1 + 3(n-1), a0 = 1, we can expand the recurrence relation iteratively.

a1 = a0 + 3(1-1) = 1 + 0 = 1

a2 = a1 + 3(2-1) = 1 + 3 = 4

a3 = a2 + 3(3-1) = 4 + 6 = 10

a4 = a3 + 3(4-1) = 10 + 9 = 19

...

We can observe a pattern from the values:

a0 = 1

a1 = 1

a2 = 4

a3 = 10

a4 = 19

We can notice that an = \(n^2 + 1.\) We can prove this by induction, but in this case, we can also recognize that the given recurrence relation generates the triangular numbers (1, 3, 6, 10, 15, ...), which are defined by the formula Tn = n(n+1)/2.

Thus, the solution to the recurrence relation is an = \(n^2 + 1.\)

b) For the recurrence relation an = an-1 + n(n-1), a0 = 3, we can again expand it iteratively:

a1 = a0 + 1(1-1) = 3 + 0 = 3

a2 = a1 + 2(2-1) = 3 + 2 = 5

a3 = a2 + 3(3-1) = 5 + 6 = 11

a4 = a3 + 4(4-1) = 11 + 12 = 23

...

Observing the values, we can notice that an =\(n(n^2 + 1).\)

Thus, the solution to the recurrence relation is an = \(n(n^2 + 1).\)

c) For the recurrence relation an = an-1 +\(3n^2\), a0 = 10, we expand it iteratively:

a1 = a0 + \(3(1^2)\) = 10 + 3 = 13

a2 = a1 + \(3(2^2) =\) 13 + 12 = 25

a3 = a2 + \(3(3^2)\)= 25 + 27 = 52

a4 = a3 + \(3(4^2)\)= 52 + 48 = 100

...

We can notice that an = \(n^3 + 10.\)

Thus, the solution to the recurrence relation is an = \(n^3 + 10.\)

two equal-size vectors at right angles to each other have a resultant that is

Answers

Two equal-size vectors at right angles to each other have a resultant that is equal to \(\sqrt{2}\) times the magnitude of each individual vector.

The magnitude of the resultant vector of two equal-size vectors at right angles to each other can be determined using the Pythagorean theorem.

Let's assume the magnitude of each vector is represented by "a".

According to the Pythagorean theorem, the magnitude of the resultant vector, denoted as "R", can be calculated as:

R =\(\sqrt{a^2 + a^2}\)

R = (\(\sqrt{2a^{2} )}\)

R = \(\sqrt{2}\) a

Suppose that an ounce of gold costs 15 U.S. dollar and 14.3028 Italian lira. An ounce of silver costs 0.7302 Italian lira and 0.1605 Swiss francs. How much Swiss franc can a U.S. dollar buy?

a. 0.23
b. 0.30
c. 0.11
d. 0.21

Answers

A U.S. dollar can buy approximately 0.21 Swiss francs (rounded to two decimal places). Thus, the answer is option d) 0.21.

To determine how much Swiss francs a U.S. dollar can buy, we need to use the given exchange rates between different currencies.

Given:

1 ounce of gold costs 15 U.S. dollars and 14.3028 Italian lira.

1 ounce of silver costs 0.7302 Italian lira and 0.1605 Swiss francs.

Let's calculate the exchange rate between the U.S. dollar and the Swiss franc using the given information:

1 ounce of silver = 0.7302 Italian lira

1 ounce of silver = 0.1605 Swiss francs

To find the exchange rate between the Italian lira and the Swiss franc, we can divide the price of 1 ounce of silver in Swiss francs by the price of 1 ounce of silver in Italian lira:

Exchange rate: 0.1605 Swiss francs / 0.7302 Italian lira

Simplifying this, we get:

Exchange rate: 0.2199 Swiss francs / 1 Italian lira

Now, let's find the exchange rate between the U.S. dollar and the Italian lira:

1 ounce of gold = 15 U.S. dollars

1 ounce of gold = 14.3028 Italian lira

To find the exchange rate between the U.S. dollar and the Italian lira, we can divide the price of 1 ounce of gold in Italian lira by the price of 1 ounce of gold in U.S. dollars:

Exchange rate: 14.3028 Italian lira / 15 U.S. dollars

Simplifying this, we get:

Exchange rate: 0.9535 Italian lira / 1 U.S. dollar

Finally, to find how much Swiss francs a U.S. dollar can buy, we multiply the exchange rate between the U.S. dollar and the Italian lira by the exchange rate between the Italian lira and the Swiss franc:

Exchange rate: 0.9535 Italian lira / 1 U.S. dollar * 0.2199 Swiss francs / 1 Italian lira

Simplifying this, we get:

Exchange rate: 0.2099 Swiss francs / 1 U.S. dollar

Therefore, a U.S. dollar can buy approximately 0.21 Swiss francs (rounded to two decimal places). Thus, the answer is option d) 0.21.

Integrated circuits from a certain factory pass quality test with probability ,8,p=,8. The outcomes of tests are mutually independent. Use The CTL to estimate the probability of finding at most of 50 acceptable circuits in a batch of 60 .

Answers

The estimated probability of finding at most 50 acceptable circuits in a batch of 60 is approximately 0.6591.

What is the estimated probability of obtaining no more than 50 acceptable circuits in a batch of 60, given a pass probability of 0.8 and independent outcomes?

To estimate the probability of finding at most 50 acceptable circuits in a batch of 60 from a certain factory, where the probability of passing the quality test is (p = 0.8) and the outcomes of the tests are mutually independent, we can use the Central Limit Theorem (CLT).

The CLT states that for a large enough sample size, the distribution of the sample mean approaches a normal distribution, regardless of the shape of the population distribution.

Let's denote (X) as the number of acceptable circuits in a batch of 60. Since each circuit passes the test with a probability of 0.8, we can model (X) as a binomial random variable with parameters (n = 60) and (p = 0.8).

To estimate the probability of finding at most 50 acceptable circuits, we can calculate the cumulative probability using the normal approximation to the binomial distribution.

Since the sample size is large \((\(n = 60\))\), we can approximate the distribution of (X) as a normal distribution with mean \(\(\mu = np = 60 \times 0.8 = 48\)\) and standard deviation \(\(\sigma = \sqrt{np(1-p)}\) = \(\sqrt{60 \times 0.8 \times 0.2} \approx 4.90\).\)

Now, we want to find the probability of\(\(P(X \leq 50)\)\). We can standardize the value using the z-score:

\(\[P(X \leq 50) = P\left(\frac{X - \mu}{\sigma} \leq \frac{50 - 48}{4.90}\right) = P(Z \leq 0.41)\]\)

Using the standard normal distribution table or calculator, we can find that \(\(P(Z \leq 0.41) \approx 0.6591\).\)

Therefore, the estimated probability of finding at most 50 acceptable circuits in a batch of 60 is approximately 0.6591.

Define the term functions limits and continuity as used in
business calculus and use an example

Answers

In business calculus, the term "functions" refers to mathematical relationships that associate inputs (typically denoted as x) with corresponding outputs (typically denoted as y). Functions can represent various aspects of business operations, such as revenue, cost, profit, demand, and supply.

The concept of "limits" in calculus deals with the behavior of a function as the input approaches a particular value. It determines the value that the function approaches or tends to as the input gets arbitrarily close to a specified value. Limits are essential for analyzing the behavior of functions near certain points, understanding rates of change, and evaluating derivatives and integrals.

"Continuity" of a function refers to its smooth and unbroken nature, without any abrupt jumps, holes, or vertical asymptotes. A function is continuous if its graph can be drawn without lifting the pen from the paper. Continuity ensures that small changes in the input correspond to small changes in the output, which is crucial for reliable analysis and prediction.

For example, consider the function f(x) = 2x + 1. This linear function represents a business scenario where x represents the number of units sold, and f(x) represents the total revenue generated. The limit of f(x) as x approaches 2 is 5, indicating that as the number of units sold approaches 2, the total revenue approaches $5. Since f(x) = 2x + 1 is a linear function, it is continuous across its entire domain.

Answers

Answer:

y = 7x

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (100, 700 ) ← 2 points on the line

m = \(\frac{700-0}{100-0}\) = \(\frac{700}{100}\) = 7

y = 7 x ← equation of line

Determine if there was a percent increase or decrease in the number of trench coats sold, and by how much. (Round your answer to the nearest tenth. ) a. The percentage of trench coats sold decreased by 0. 8%. B. The percentage of trench coats sold increased by 0. 8%. C. The percentage of trench coats sold decreased by 23. 3%. D. The percentage of trench coats sold increased by 23. 3%.

Answers

The percentage of trench coats sold increased by 23. 3%. therefore, option D is correct.

What is the percentage?

A percentage is a minimum number or ratio that is measured by a fraction of 100.

First, we need to subtract the final from the initial, then divide the difference by the initial, then multiply your answer by 100 to get the percentage

the final is 127, and the initial is 103

127 - 103 = 24

24/103 = 0.233

0.233 x 100

= 23.3%

Thus, The percentage of trench coats sold increased by 23. 3%.

The regular price, in dollars, the gym charges can be represented by the equation y=15x+20
B.How much money, in dollars, does justin save the first month by joining the gym at the discounted price rather than at the regular price?

Answers

The amount of money Justin saves in the first month would be 5 times the value of x, where x represents the number of months of gym membership, based on the discounted price provided.

What is the linear equation?

A linear equation is an equation in mathematics that represents a relationship between two variables that is a straight line when graphed on a coordinate plane. It is an equation of the form:

y = mx + b

To calculate the amount of money Justin saves in the first month by joining the gym at the discounted price rather than the regular price, we need to know the discounted price.

The equation given is y = 15x + 20, where y represents the regular price in dollars and x represents the number of months of gym membership. However, we need to know the discounted price, which is not provided in the given information.

Once we have the discounted price, we can substitute it into the equation and calculate the savings. For example, if the discounted price is y = 10x + 20, then we can calculate the savings by subtracting the discounted price from the regular price:

Savings = Regular price - Discounted price

= (15x + 20) - (10x + 20)

= 15x - 10x

= 5x

Hence, the amount of money Justin saves in the first month would be 5 times the value of x, where x represents the number of months of gym membership, based on the discounted price provided.
