Answer:

y = one-half x minus 1

Step-by-step explanation:

We are to find the inverse of a equation.

The given equation: y = 2x + 2

It is a linear equation: y = mx + b

To find its inverse of the equation, first we would interchange the position of the variables x and y

y = 2x + 2

x = 2y + 2

Then we make y the subject of formula.

x-2 = 2y

2y = x-2

y = (x-2)/2

y = x/2 - 2/2

y = x/2 - 1

Hence, the inverse of y = 2x+2 is

y = x/2 - 1

The inverse of y = 2x + 2 is y = one-half x minus 1

Answer:

y=1/2x-1

Step-by-step explanation:

Since the diagonals of a square are equal, they bisect each other and form 4 right angles.

Therefore, we have two congruent right triangles with legs x/2 and hypotenuse x. Using the Pythagorean theorem, we can solve for x:

(x/2)^2 + (x/2)^2 = x^2

2(x/2)^2 = x^2

x^2/2 = x^2

1/2 = 1

This leads to an absurdity, so there is no solution for x that satisfies the given conditions. Therefore, the answer is 4.0 Units.

Answer:

C

Step-by-step explanation:

The reason it is C is mainly because it is the only line with a negative slope. A negative slope this direct \. It is not A because that is a positive slope (/). It is not B because that line is undefined which means it would look like this x = 2. And D is wrong because that is a zero slope line which looks like this y = 5. So it is C.

First begin with the interest formula.

Interest = Principal x Rate x Time

The $250 is the principal is the amount of money invested.

The rate is 4% which translates to the decimal .04.

The time is 5 years.

So we have I = (250)(.04)(2).

Multiplying, (25)(.04) is 10 and we have 10(2) which is 20.

This means that the interest earned in 2 years is $20.

The Methods used that summarize or organize characteristics of data is descriptive.

Methods used to summarize or organize characteristics of data are referred to as descriptive methods.

Descriptive methods are used to describe the basic features of a set of data, such as its central tendency (mean, median, mode) and dispersion (range, variance, standard deviation). These methods provide a summary of the data, often through the use of graphical representations such as histograms, bar charts, and scatter plots.

The goal of descriptive methods is to understand the underlying structure of the data, identify patterns, and present the data in a clear and meaningful way.

Descriptive methods do not make inferences about a population based on a sample or draw conclusions about causality.

After forty years with interest compounded every twenty years, the total amount will be ₹100,625 and the total interest will be ₹50,625.

In this scenario, the principal amount is ₹50,000, and the rate of interest is 0.5% per annum. The interest is compounded every twenty years, which means that after twenty years, the interest earned is added to the principal, and the new total becomes the principal for the next twenty-year period.

To calculate the total amount after forty years, we need to compound the interest twice. First, we calculate the amount after twenty years:

Principal + Interest = ₹50,000 + (0.5% of ₹50,000) = ₹50,000 + (0.005 * ₹50,000) = ₹50,000 + ₹250 = ₹50,250.

Then, for the next twenty-year period, we compound the interest again:

Principal + Interest = ₹50,250 + (0.5% of ₹50,250) = ₹50,250 + (0.005 * ₹50,250) = ₹50,250 + ₹251.25 = ₹50,501.25.

Therefore, after forty years, the total amount will be ₹50,501.25. The total interest earned can be calculated by subtracting the principal amount from the total amount:

Total Interest = Total Amount - Principal = ₹50,501.25 - ₹50,000 = ₹501.25.

Hence, the total interest earned after forty years will be ₹501.25, and the total amount will be ₹50,501.25.

Step-by-step explanation:

The relation of interest between the sides of the right triangle is ...

  Tan = Opposite/Adjacent

Using the given numbers, that is ...

  tan(32°) = (building height)/(4300 ft)

Multiplying by 4300 ft, we get ...

  building height = (4300 ft)·tan(32°) ≈ 2686.9 ft

This is the height above the observer's eyes, so the height of the building above the ground is ...

  2687 +5 = 2692 . . . . feet

The building is 2692 feet tall.

Step-by-step explanation: The solution to this system of equations will be where the two lines on the graph intersect with each other.

Notice that both of them intersect to the left of the y-axis which means our x - coordinate must be negative.

They also intersect above the x-axis so our y-coordinate must be positive.

So the only option with a negative x-coordinate

Step-by-step explanation:

The farmer will make 14 baskets containing each of 5 apples and 7 peaches.

In mathematics, the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted {\displaystyle \gcd}.

here, we have,

How many baskets can be made which contain both apples and peaches and each basket should contain the same combinations of fruits?

Given:

A farmer harvests 70 apples and 98 peaches.

They want to make baskets that have both apples and peaches to sell at the market.

Each basket should contain the same combinations of fruit.

They want to sell all the apples and peaches and as many baskets as possible.

Find:

How many baskets can the farm make having x apples and y peaches in the baskets?

Solution:

So, for solving this kind of question first we have to find the greatest common factor, we get;

70 = 2*5*7

98 = 2*7*7

the common factor are 2 and 7

the greatest common factor is 2*7=14

70 apples = 14*5

98 peaches = 14*7

So, the farmer will make 14 baskets each of 5 apples and 7 peaches.

Step-by-step explanation:

So, if 3 points were added to every score in the population, the new mean would be the old mean plus 3, and the new standard deviation would be the same as the old standard deviation.

Given,

3 points were added to every score in the population,

Adding a constant value to every score in a population will not change the standard deviation of the population, only the mean will change.

If we add 3 to every score in the population, the new mean will be the old mean plus 3. Let's say the old mean is μ and the old standard deviation is σ. Then the new mean will be μ + 3, and the new standard deviation will still be σ.

So, if 3 points were added to every score in the population, the new mean would be the old mean plus 3, and the new standard deviation would be the same as the old standard deviation.

Answer:

1st:  81.8

2nd:  82

3rd:  Language arts class

Step-by-step explanation:

1st:  We're told that f(x) = 0.4x + 81 represents the avg. test score in your language arts class, where x is the number of the test taken.  We know then that f(x) is the average test score.  Thus, to find the average test score for test 2, we plug in 2 for x into the function:

f(2) = 0.4(2) + 81

f(2) = 0.8 + 81

f(2) = 81.8

2nd:  Although we're not given the formula for g(x), we know that it is linear and have enough information to find the formula.

The general form for a linear formula is y = mx + b, where m is the slope (change in y / change in x) and b is the y-intercept (point for y when x = 0)

We can find the slope using the slope formula, which is:

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

We can use any two consecutive points to find the slope:

*Note that y is synonymous with g(x)

Thus, if we allow (1, 84) to represent x1 and y1 and (2, 82) to represent x2 and y2, our slope is:

\(m=\frac{82-84}{2-1}\\ m=-2\)

Now, we can choose any point like (1, 84) and plug in the point and the slope we've found to find b or our y-intercept:

\(84=-2(1)+b\\84=-2+b\\86=b\)

Thus, the formula for g(x) is g(x) = -2x + 86.

Like we did for f(x), we can simply plug in 2 for x to find the average test score for test 2 in your social studies class:

g(2) = -2(2) + 86

g(2) = -4 + 86

g(2) = 82

Third: To find which class had a higher average after completing test 4, we plug in 4 into each function:

f(4) = 0.4(4) + 81

f(4) = 1.6 + 81

f(4) = 82.6

g(4) = -2(4) + 86

g(4) = -8 + 86

g(4) = 78

Therefore, the language arts class had a higher average score for test 4 than the social studies class.

In sigma notation, the sum is represented as follows: ∑ (k^2 + 1), k = 1 to 2.

The given sum is: 12 + 22 + 32 + 132.

To write this sum using sigma notation, we can observe the pattern in the terms. The first term is 12, the second term is 22 (which is 12 + 1), the third term is 32 (which is 22 + 1), and the fourth term is 132 (which is 32 + 1 + 2).

We can see that each term is obtained by adding the square of the position number (k^2) to the previous term, along with an additional constant value of 1 or 2 depending on the position.

So, let's write the sum using sigma notation:

∑ [(k^2 + c(k-1))], where k starts from 1 and goes up to 4.

In this notation, k represents the position of the term, k^2 represents the square of the position number, and c represents the constant value added to the previous term.

For the given sum, the constant value c changes depending on the position of the term:

For the first term (k = 1), c is 1.

For the second term (k = 2), c is 1.

For the third term (k = 3), c is 1.

For the fourth term (k = 4), c is 2.

So, the corrected sigma notation for the given sum is:

∑ [(k^2 + c(k-1))], k = 1 to 4.

This indicates that we sum the terms (k^2 + c(k-1)) as k takes values from 1 to 4, where c changes based on the position of the term.
