The given expression of the values of the function, f(3) - g(2) = 1

A function is a relation that relates each element of one set a unique element of another set.

If f is a function and f (x) = x+2, The  value of  f (x) at x =1 is given as f(1) and substitute 1 in place of x in the formula of f(x)

⇒ f(1) = 1+2 =3

If f(x) = 3x-4 and g(x) = x², find the value  of f(3) - g(2)

Given f(x) = 3x-4

Then value of f at x=3 ⇒ f(3) = 3(3) -4 = 9-4 = 5

And Given g(x) = x²

Then value of g at x=2 ⇒ g(2) = (2)² = 4

The value f(3) - g(2) = 5 - 4 = 1

Therefore, the value of f(3) - g(2)  is 1.

What is radioactive decay?

The process of radioactive decay is how an unstable atomic nucleus loses energy through radiation. A substance that has unstable nuclei is regarded as radioactive.

Here,

The half-life of the reaction is defined as the time required by a substance to reach half its initial concentration. It is represented by t(1/2)

 All radioactive decay processes follow the first-order reaction.

The equation for the half-life for first-order reaction follows:

t(1/2) = 0.693/k....(1)

where,

k = rate constant of a first-order reaction

Given value:

t(1/2) = 5715 years

Put the value of t in equation (1), and we get

k = 0.693/5715

k = 1.21×10⁻⁴yr

The integrated rate law expression for first-order reaction follows:

t = 2.303/k×㏒(a/(a-x))

where,

t = time period

a = initial concentration of the reactant = 58.2 counts per minute

(a-x) = Concentration of reactant left after time t = 38.0 counts per minute

k = rate constant of a first-order reaction

Put the values in the equation and we get

t = 2.303/1.21×10⁻⁴㏒58.2/38

t = 3523.77 years.

Hence, the age of the artifact is 3523.77 years.

First, we need a few things.

The first term = 26

The common difference = 22 - 26 = -4

26 - 4(n - 1) is our equation.

Let's plug 50 into n to find a50

a50 = 26 - 4(50 - 1)

a50 = 26 - 4(49)

a50 = 26 - 196

To write the given system in the form of d/dt [x y] = P(t) [x y] + f(t), we need to express it in matrix form.

Let's rewrite the system of differential equations:

x' = e^(8tx) - 2ty + 6sin(t)

y' = 8tan(t)y + 6x - 8cos(t)

Now, we can rewrite it in matrix form as:

[d/dt [x y]] = [P(t) [x y] + f(t)],

where [x y] represents the vector [x y] and P(t) is the coefficient matrix.

Comparing the coefficients, we have:

P(t) = [[e^(8tx) - 2t, 6], [6, 8tan(t)]]

f(t) = [6sin(t), -8cos(t)]

Therefore, the system can be written in the desired form as:

d/dt [x y] = [[e^(8tx) - 2t, 6], [6, 8tan(t)]] [x y] + [6sin(t), -8cos(t)].

The approximate length of the actual object is 1465 ft, which is closest to option D.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

First, let's convert the length of the model from millimeters to inches:

372.5 mm = 372.5/10 cm = 37.25/2.54 in ≈ 14.65 in

Next, we can use the scale of the model to find the length of the actual object in feet:

0.5 in. = 50 ft.

So, 1 in. = 100 ft.

Therefore, the length of the actual object in feet is:

14.65 in x (100 ft/in) = 1465 ft

Therefore, the closest length is 1467 feet.

a) Median will be an appropriate measure for the distribution. b) Mean will be an approprate measure for the distribution.

Here we already have the data available to us. From the data, we can clearly see that

Mode < Mean < Median

Hence this is a negatively skewed distribution.

Therefore the appropriate measure of central tendency for this distribution will be the median. The median will tell us the point at which the frequency is divided by 50%.

Hence we can say that the median will a more appropriate measure.

Now if the data has another aspect of sex included, then the frequency column would be divided into separate columns with each gender identity taking up its own column.

Since now this will become multivariate data, the best measure of central tendency will be Mean.

The difference in the measure of central tendency will depend upon how skewed the data for every sex will be. For example, if in a country, men preferred to be educated over women, then the mean for men will be a lot higher than that of women. On the other hand, the EDUC for women will be a lot lower.

Answer:

x=3, y=5

Step-by-step explanation:

Using the four-step process,  f'(1) = 10, f'(2) = 12, and f'(3) = 14.

To identify f'(x), the derivative of f(x), using the four-step process, we can follow these steps:

1: Identify the function.
The given function is f(x) = x^2 + 8x - 6.

2: Apply the power rule.
Differentiate each term of the function separately.
The derivative of x^2 is 2x.
The derivative of 8x is 8.
The derivative of -6 is 0 (constant term).

3: Simplify.
Combine the derivatives obtained in step 2.
So, f'(x) = 2x + 8.

4: Evaluate f'(1), f'(2), and f'(3).
Substitute x = 1, 2, and 3 into the derived equation to identify the respective values.
f'(1) = 2(1) + 8 = 10.
f'(2) = 2(2) + 8 = 12.
f'(3) = 2(3) + 8 = 14.

The depth of the scientist below sea level after traveling downward for 102 seconds can be found by multiplying her speed by the time she traveled:

Distance = Speed x Time

Distance = 4.2 feet/second x 102 seconds

Distance = 428.4 feet

Since she traveled straight down, this distance is also her depth below sea level.

Next, we need to find how far she ascended. The distance she traveled upward can be found in the same way:

Distance = Speed x Time

Distance = 1.9 feet/second x 112 seconds

Distance = 212.8 feet

However, since she traveled upward, this distance is subtracted from her previous depth:

Final depth below sea level = Initial depth below sea level - Distance traveled upward

Final depth below sea level = 428.4 feet - 212.8 feet

Final depth below sea level = 215.6 feet

Therefore, the scientist is 215.6 feet below sea level at this point.

Answer: 430,000. /four hundred thirty thousand

Step-by-step explanation:

The value of 4.3 x 10^5 is 430,000.

To understand this, the notation 4.3 x 10^5 represents a number in scientific notation, where 4.3 is the coefficient or significand, and 10^5 is the exponent. The exponent of 10 tells us how many places to move the decimal point to the right. In this case, the exponent 5 means we need to move the decimal point five places to the right.

Starting with 4.3, we move the decimal point five places to the right to get 430,000. So, 4.3 x 10^5 is equivalent to 430,000.

The least square regression line is:

\(\hat y=-7.567857143+0.917857143\cdot x\\\\\approx \\\\\hat y=-7.568+0.918\cdot x\)

Here,

y = estimated sales of makeup

x = number of online makeup tutorial videos

a = -7.568 = intercept

b = 0.918 = slope of the regression line

B.

The coefficient of determination R² specifies the percentage of the variance in the dependent-variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent-variable).

So, the proportion of the variation in makeup sales that can be explained by its linear relationship to makeup tutorial videos is 99.53%.

C.

Consider the LSRL.

The slope of the regression line is positive, i.e. there is a positive relationship between the makeup sales and the online makeup tutorial videos.

So, with one unit increase in the online makeup tutorial videos the makeup sales goes up by 0.918 units.

Thus, it can be said that the increased makeup sales were caused by online makeup tutorial videos.

The relation "r" on the set of all integers, where x = y^2, is not reflexive.

A relation is reflexive if every element in the set is related to itself. In this case, for the relation x = y^2 to be reflexive, every integer "x" should be related to itself, meaning that x = x^2. However, this is not true for all integers.

For example, if we consider x = 2, it is not equal to 2^2 = 4. Similarly, if we consider x = -3, it is not equal to (-3)^2 = 9.

Since there are integers that do not satisfy the condition x = x^2, the relation x = y^2 is not reflexive on the set of all integers.

The length of the major diameter of the ellipse is 4.

The equation of the given ellipse is 12x² + 2x + y² = 1. To determine the length of the major diameter, we need to find the distance between the two farthest points on the ellipse along its major axis.

The general equation of an ellipse is (x-h)²/a² + (y-k)²/b² = 1, where (h, k) represents the center, a represents the length of the semi-major axis, and b represents the length of the semi-minor axis.

Comparing the given equation to the general equation, we can see that the coefficient of x² is 12, indicating that the length of the semi-major axis is 1/√12 = √(1/12) = 1/(2√3) = √3/6.

Since the major diameter is twice the length of the semi-major axis, the length of the major diameter is 2 * (√3/6) = √3/3. Simplifying, we get the final answer: the length of the major diameter of the given ellipse is 4.
