Question 6: What are the vertex and range of y = |x - 2 + 1? *

Answer:

W when c = 4 is 0.128.

Step-by-step explanation:

The relationship between A, C and W can be represented by the following equations:

A = k√c

W = m/a^3

Where k and m are constant of proportionality.

Since A is directly proportional to the square root of c, we can write k = A/√c. Substituting the values of A and C when c = 49, we have:

k = 35/√49 = 35/7

Since W is inversely proportional to a^3, we can write m = W * a^3. Substituting the values of W and A when a = 2, we have:

m = 16 * 2^3 = 128

Now we have both k and m, we can find the value of W when c = 4.

A = k * √c = 35/7 * √4 = 10

W = m/a^3 = 128/10^3 = 0.128

So, the value of W when c = 4 is 0.128.

There 144 four digit numbers are made up of four consecutive numbers from 1 to 9

We can approach this problem by counting the number of ways we can choose four consecutive numbers from 1-9 and then arranging them in a four-digit number.

Here we have to use combination

There are 6 possible sets of four consecutive numbers in the range 1-9

= {1,2,3,4}, {2,3,4,5}, {3,4,5,6}, {4,5,6,7}, {5,6,7,8}, and {6,7,8,9}.

For each set, there are 4! = 24 ways to arrange the four numbers into a four-digit number.

So the total number of four-digit numbers made up of four consecutive numbers from 1-9 is:

6 sets × 24 arrangements per set = 144

Therefore, there are 144 such four-digit numbers.

a.) The equation for g(x) is g(x) = 6((x+5)/2)³and output is 384.

b.) The inverse machine, g¹(a), we need to undo each of the four steps in reverse order is g¹(a) = [tex]((a/6)^{(1/3)})*[/tex]2 - 5

c.) To verify that g¹(a) correctly "undoes" the output of g(x), we can plug in the output of g(3) (384) into g¹(a) and see if we get 3 as the result is  3.

What is Function?

A function is a mathematical rule that takes one or more inputs (also called independent variables or arguments) and produces a single output (also called a dependent variable or function value). In other words, a function is a relationship between the inputs and the output, where each input produces a unique output.

Functions can take many different forms and can be used to describe a wide variety of mathematical and real-world phenomena.

a. The equation for g(x) is:

g(x) = 6((x+5)/2)³

When 3 is put in for x, the output is:

g(3) = 6((3+5)/2)³= 6(4)³ = 384

b. To find the inverse machine, g¹(a), we need to undo each of the four steps in reverse order:

Putting this in equation form, we get:

g¹(a) = [tex]((a/6)^{(1/3)})[/tex]*2 - 5

c. To verify that g¹(a) correctly "undoes" the output of g(x), we can plug in the output of g(3) (384) into g¹(a) and see if we get 3 as the result:

g¹(384) =[tex]((384/6)^{(1/3)})[/tex]*2 - 5 =[tex](64^{(1/3)})[/tex]2 - 5 = 42 - 5 = 3

Since the output of g¹(a) is 3 when we input the output of g(x), we can conclude that g¹(a) correctly undoes the output of g(x).

Answer: 37

Step-by-step explanation:

let x be the number of students who pass "fante". Then the number of students who passed "Ga" will be x + 6.

with the added information that 8 students passed both we can say:

(x + x + 6) - 8 = 60

2x + 6 = 68

2x = 62

x = 31

.: x + 6 = "only Ga pass" = 37

The question does not make it clear if it is asking for students who *only* passed Ga, or students who passed Ga + those who passed both. I'll assume the former though. Otherwise the answer would be 37 + 8 = 45 students

A quadratic equation with -1 and 5 as its roots is x^2 - 4x - 5 = 0 by multiplying the terms.

The roots of a quadratic equation are the values of the variable that satisfy the equation. They are also known as the "solutions" or "zeros" of the quadratic equation.

Derive factor from the roots

x = -1    and    x = 5

x + 1 = 0  and  x - 5 = 0

Now, (x+1)(x-5) = 0

 x(x - 5) + 1(x - 5) = 0

No, f(x, y) = 3x - 3y^2 is not a harmonic function.

A harmonic function is a twice continuously differentiable function f(x, y) that satisfies the Laplace equation:
                                                                            ∂²f/∂x² + ∂²f/∂y² = 0.

Let's check if f(x, y) = 3x - 3y^2 satisfies the Laplace equation:
∂²f/∂x² = ∂/∂x(3) = 0
∂²f/∂y² = ∂/∂y(-6y) = -6
∂²f/∂x² + ∂²f/∂y² = 0 + (-6) = -6 ≠ 0

Since the Laplace equation is not satisfied, f(x, y) = 3x - 3y^2 is not a harmonic function.

As for finding a corresponding analytic function, an analytic function is a function that is locally given by a convergent power series. Since f(x, y) is not a harmonic function, there is no corresponding analytic function.

An appropriate scale for the y-axis would be to have each unit represent 5 minutes of time.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Since the data represents the average time employees spent online, the y-axis of the bar graph should represent time in minutes.

To choose an appropriate scale for the y-axis.

we need to consider the range of values in the data set.

The lowest value is 15 minutes

and the highest value is 60 minutes

Range of values is 60 - 15 = 45 minutes.

It's best to choose a scale that divides the range of values into equal intervals.

One possible option is to use a scale where each unit represents 5 minutes of time. This would allow us to represent the data accurately without making the bars too small or too large.

Anyways,

The height of the nth bounce can be calculated using the formula:

h_n = h_1 * 0.68^(n-1)

Where h_1 is the height of the first bounce, h_n is the height of the nth bounce, and 0.68 is the percentage of the height lost with each successive bounce.

Substituting the given values, we have:

h_9 = 5 * 0.68^(9-1)

h_9 = 5 * 0.68^8

h_9 = 5 * 0.265

h_9 = 1.325

So the height of the 9th bounce would be approximately 1.3 feet, rounded to the nearest tenth.

These are the four points that are exactly 5 units away from point W. To find points that are 5 units from point W, which is located at (-5, -3).

To find points that are 5 units from point W, which is located at (-5, -3), we need to find all points that are a distance of 5 units away from (-5, -3) using the Pythagorean theorem.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the distance between two points) is equal to the sum of the squares of the lengths of the other two sides

Given a point (x, y), the distance between that point and point W can be found using the formula:

distance = sqrt((x + 5)^2 + (y + 3)^2)

Setting this distance equal to 5 and solving for x and y, we get the following points:

The total cost of the cement rings for the water well is RS. 70,000. This cost is only for the cement rings and does not include the cost of labour for digging the well.

The cost of each cement ring is given as RS. 2500. Since there are 28 cement rings used in the water well, the total cost of the cement rings can be calculated as follows:

Total cost of cement rings = Cost of each cement ring x Number of cement rings used

Total cost of cement rings = 28 x 2500 = RS. 70,000

Volume of the well = [tex]\mathrm{ \pi r^2h = \pi (0.7)^2(5.6) = 9.768m^3 }[/tex]

Cost of digging out the well = 500 x 9.798 = RS. 4,899

Total cost of the well = RS. 74,899

Total cost of cement rings = 2500 x 28 = RS. 70,000

The cheapest option for Jane is to buy from Suttons Shop, as the total cost is £12, whereas, at Greens Garden Shop, the total cost is £9.98.

To determine the cheapest option, we need to calculate the cost of purchasing 140 liters of compost from each shop.

First, we'll calculate the cost at Suttons Shop:

Jane needs 140 liters of compost, so she needs 140 / 20 = 7 bags of compost.

If she buys 1 bag of compost, it will cost her £2.25.

If she buys 2 bags of compost, it will cost her £3.25.

Since she needs 7 bags of compost, she can buy 3 sets of 2 bags (6 bags) and 1 bag.

So the cost of 6 bags will be 3.25 x 3 = £9.75, and the cost of 1 bag will be 2.25.

The total cost of 7 bags at Suttons Shop will be 9.75 + 2.25 = £12.

Next, we'll calculate the cost at Greens Garden Shop:

Jane needs 140 liters of compost, so she needs 140 / 70 = 2 bags of compost.

Each bag at Greens Garden Shop costs £4.99.

So the total cost of 2 bags at Greens Garden Shop will be 4.99 x 2 = £9.98.
