Carbon 14 has a half-life of 5,600 years, which means that after 5,600 years, half of the initial amount of Carbon 14 will decay. Therefore, we can use the following formula to find the amount of Carbon 14 that was present 11,200 years ago:

A = A0 * (1/2)^(t/T)

where:

A0 = initial amount of Carbon 14

A = amount of Carbon 14 remaining after time t

t = time elapsed since the initial amount was present

T = half-life of Carbon 14

We know that the fossil contains 3 g of Carbon 14, which is the amount remaining after 11,200 years. We want to find the initial amount, A0.

Let's plug in the values we have into the formula and solve for A0:

3 g = A0 * (1/2)^(11,200/5,600)

3 g = A0 * (1/2)^2

3 g = A0 * 1/4

A0 = 4 * 3 g

The mean of the data in the dot plot is approximately 5.33.

By dividing the sum of the numbers by the total number of numbers, the mean, or average, of the given numbers is determined. Mean is equal to (Sum of all Observations / Total Observations).

We must sum up all the values and divide by the total number of values to determine the mean of the data in the dot plot.

The first step is to count the dots for each value:

3 has 3 dots

4 has 5 dots

5 has 6 dots

6 has 8 dots

7 has 5 dots

8 has 3 dots

Then, multiplying each value by the quantity of dots associated with it, we must total up all the products:

(3 x 3) + (4 x 5) + (5 x 6) + (6 x 8) + (7 x 5) + (8 x 3) = 3 + 20 + 30 + 48 + 35 + 24 = 160

Last but not least, we must divide the entire number of values—i.e., dots—by the sum:

Answer:

Let's start by using algebra to represent the given information.

Let the son's current age be "s" and the mother's current age be "m". We know from the problem that:

m = 3s (the mother is 3 times as old as her son is now)

and

m - 14 = 10(s - 14) (fourteen years ago, the mother was 10 times as old as her son was then)

Now we can solve for the son's age:

m - 14 = 10s - 140 (distribute the 10)

m = 10s - 126 (add 14 to both sides)

3s = 10s - 126 (substitute m = 3s)

7s = 126

s = 18

Therefore, the son is currently 18 years old. To check this answer, we can use the first equation to find the mother's current age:

m = 3s = 3(18) = 54

So the mother is currently 54 years old, and 14 years ago the son was 4 years old and the mother was 40 years old, which is 10 times as old as the son.

The answer of the given question based on the function is ,  the turning point of the function f(x+4)+5 is at the point (-4, -5).

In mathematics, a function is a rule that assigns each input value (or argument) in a set to a unique output value in another set. In other words, it is a relationship between two sets of numbers, where each input value produces exactly one output value. Functions are usually represented using function notation, where the name of the function is followed by the input value in parentheses.

To find the turning point of the function f(x+4)+5, we need to first rewrite the function in vertex form, which is given by:

f(x) = a(x-h)² + k

where (h, k) is vertex of parabola.

To do this, we can start by completing the square:

f(x+4) + 5 = a(x+4-h)² + k

f(x+4) = a(x+4-h)² + k - 5

To complete the square, we need to add and subtract (4-h)²/4a inside the parentheses:

f(x+4) = a(x+4-h)² + k - 5 + (4-h)²/4a - (4-h)²/4a

f(x+4) = a(x+4-h)² + (4-h)²/4a + (4a*k-20a)/4a

Now the function is in vertex form:

f(x+4) = a(x+4-h)² + (4-h)²/4a + (4a*k-20a)/4a

The vertex of the parabola is at (h, k), so in this case, the vertex is at (-4, -5).

Therefore, the turning point of the function f(x+4)+5 is at the point (-4, -5).

The probability that a randomly selected bicyclist who tests positive for steroids actually uses steroids is 0.763 (rounded to three decimal places).

We can use Bayes' theorem to calculate the probability that a randomly selected bicyclist who tests positive for steroids actually uses steroids. Let A be the event that a randomly selected bicyclist uses steroids, and B be the event that a randomly selected bicyclist tests positive for steroids. Then, we want to find P(A|B), the probability that a bicyclist uses steroids given that they test positive for steroids:

P(A|B) = P(B|A) * P(A) / P(B)

where P(B|A) is the probability of testing positive given that the bicyclist uses steroids, P(A) is the prior probability of a bicyclist using steroids, and P(B) is the probability of testing positive for steroids.

We are given that P(A) = 0.08, P(B|A) = 0.94, and P(B|not A) = 0.09. We can calculate P(B) using the law of total probability:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

= 0.94 * 0.08 + 0.09 * 0.92

= 0.0976

where P(not A) = 1 - P(A) = 0.92.

Substituting the values we have:

P(A|B) = 0.94 * 0.08 / 0.0976

= 0.763

Therefore, the probability that a randomly selected bicyclist who tests positive for steroids actually uses steroids is 0.763 (rounded to three decimal places).

The following are the correct vertical translation and you can use this information to fill the table in the picture:

A vertical translation refers to a type of transformation that moves a function or graph vertically up or down without changing its shape. Specifically, a vertical translation of distance c is given by the function:

f(x) + c

where f(x) is the original function and c is a constant that determines the amount and direction of the translation. If c is positive, the graph of the function is shifted upwards; if c is negative, the graph is shifted downwards.

For example, the function f(x) = x^2 has a graph that is a parabola opening upwards. If we apply a vertical translation of 2 units, the resulting function is:

f(x) + 2 = x^2 + 2

The graph of this function is also a parabola, but it has been shifted vertically upwards by 2 units. Similarly, a vertical translation of -3 units would give us the function f(x) - 3 = x^2 - 3, which is the same parabola shifted downwards by 3 units.

Answer:

-8.5 and 7.5

Step-by-step explanation:

Let's call the two numbers x and y. We know that their difference is 16, so we can write:

x - y = 16 or x = y + 16

We want to find the values of x and y that minimize the expression:

x + y + xy

Substituting x = y + 16, we get:

(y + 16) + y + (y + 16)y

Simplifying and expanding, we get:

y^2 + 17y + 16

To minimize this expression, we can take its derivative with respect to y and set it equal to 0:

d/dy (y^2 + 17y + 16) = 2y + 17 = 0

Solving for y, we get:

y = -8.5

Substituting y = -8.5 into x = y + 16, we get:

x = 7.5

Therefore, the two numbers with a difference of 16 such that the result of adding their sum and their product is a minimum are -8.5 and 7.5.

The equation of the line that passes through the point (16, -14) with slope 1 is y = x - 30.

What is meant by equation?

An equation is a mathematical statement that shows that two expressions are equal. It contains an equals sign and can include variables, constants, and mathematical operations. Equations are used to represent relationships between quantities and to solve problems in mathematics and science.

What is meant by slope?

Slope refers to the measure of the steepness of a line. It is calculated by dividing the change in the y-coordinate (vertical distance) by the change in the x-coordinate (horizontal distance) between two points on the line.

According to the given information

The point-slope form of the equation of a line is given by:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line and m is the slope of the line.

In this case, the line passes through the point (16, -14) and has a slope of 1. Plugging these values into the point-slope form, we get:

y - (-14) = 1(x - 16) y + 14 = x - 16 y = x - 30

So, the equation of the line that passes through the point (16, -14) with slope 1 is y = x - 30.

The solutions to the system of equations f(x) = x² + x - 6 and g(x) = -2x² - 2x + 12 are (-3, 0) and (2, 0). So, correct option is 1.

To graph the functions f(x) and g(x) using a calculator, we can enter the equations into the calculator's graphing function and choose an appropriate window to display the graph. Once the graphs are displayed, we can look for the points of intersection to find the solution to the system of equations.

Using a graphing calculator, we can see that the graphs of f(x) and g(x) intersect at two points: (-3, 0) and (2, 0). These points represent the x-coordinates of the solutions to the system of equations.

To verify that these points are indeed the solutions, we can substitute each of them into both equations and check that they satisfy both equations simultaneously.

For point (-3, 0):

f(-3) = (-3)² + (-3) - 6 = 0

g(-3) = -2(-3)² - 2(-3) + 12 = 0

Therefore, (-3, 0) is a solution to the system of equations.

For point (2, 0):

f(2) = 2² + 2 - 6 = 0

g(2) = -2(2)² - 2(2) + 12 = 0

Therefore, (2, 0) is also a solution to the system of equations.

The point (0, -6) and (0, 12) are not the points of intersection and (-6, 12) is not a solution to the system of equations.
