Answer:8 over 4

Step-by-step explanation:

Rise over run

the derivative of function g(x) = \(3(x^3-6)^2(x^2 + 4x - 6)^{10} is:g'(x) = 3 * [2(x^3-6)(3x^2)(x^2 + 4x - 6)^{10} + (x^3-6)^2 * 10(x^2 + 4x - 6)^9(2x+4)]\)

To differentiate the function\(g(x) = 3(x^3-6)^2(x^2 + 4x - 6)^{10}\), we can use the chain rule and the power rule for differentiation.

Let's break it down step by step:

1. Start by differentiating the outermost function with respect to x. The outermost function is\((x^3-6)^2(x^2 + 4x - 6)^{10}\), which we'll call f(x). Let's denote it as \(f(x) = (x^3-6)^2(x^2 + 4x - 6)^{10}.\)

2. Differentiate f(x) using the product rule. Let's call the first factor (x^3-6)^2 and the second factor \((x^2 + 4x - 6)^{10}\). The derivative of f(x) is given by:

\(f'(x) = (2(x^3-6)(3x^2)) * (x^2 + 4x - 6)^{10} + (x^3-6)^2 * (10(x^2 + 4x - 6)^9(2x+4))\)

3. Simplify the expression:

\(f'(x) = 2(x^3-6)(3x^2)(x^2 + 4x - 6)^{10} + (x^3-6)^2 * 10(x^2 + 4x - 6)^9(2x+4)\)

4. Finally, substitute f(x) back into the expression to obtain the derivative of g(x):

g'(x) = f'(x) * 3

Question: In a sale, the price of a book is reduced by 25%. The price of the book in the sale is £12. Work out the original price of the book

Answer: £16

Step-by-step explanation:

To determine the original price of the book, we can use the fact that the sale price is 75% (100% - 25%) of the original price. Let's denote the original price as x.

75% of x = £12

To solve for x, we can set up the equation:

0.75x = £12

To isolate x, we divide both sides of the equation by 0.75:

x = £12 / 0.75

x = £16

Therefore, the original price of the book was £16.

The volume of the solid is approximately 807.08 cubic units.

To determine the volume of the solid, we can use the method of cylindrical shells.

Imagine taking a slice of the solid parallel to the base, with the cross-sectional area being a square of side length x (where x is a function of the height). The volume of this slice is the product of the square area and the height. The height of the slice is equal to the difference in the radii of two consecutive circular cross sections.

The radius of the larger circular cross-section can be found using the Pythagorean theorem, which states that the square of the hypotenuse (the radius) is equal to the sum of the squares of the other two sides (the height and half the side length of the square). Thus, we have:

r² = x² + (15-x)²

Solving for x, we get:

x = 15 * √(1 - (r/15)²)

The volume of the slice is then given by:

V = x² * (15 - x)

To find the total volume of the solid, we integrate this expression with respect to r from 0 to 15. The result is approximately 807.08 cubic units.

There are 29 data values in this data set. The minimum value in the last class is 60.

To determine the number of data values in the data set, we need to count the values represented in the stem-and-leaf plot. By examining the plot, we can count the values in each class and sum them up. In this case, there are a total of 29 data values in the data set.

To find the minimum value in the last class, we look at the rightmost leaf of the last stem in the stem-and-leaf plot. The last class is represented by the stem "6" and contains the values 60 and 69. Therefore, the minimum value in the last class is 60.

To determine the frequency of the modal class, we need to identify the class with the highest frequency. The mode represents the most frequently occurring value or class in the data set. In this case, the class with the highest frequency is the one with the stem "4" and the leaves "4, 4, 4, 6, 7, 8, 9, 9". The frequency of this class is 8, so the modal class has a frequency of 8.

To find the number of original values that are greater than 50, we examine the stem-and-leaf plot. We can see that all the values with stems greater than "5" are greater than 50. From the plot, we observe that there are 8 values in the "6#" class and 2 values in the "7#" class, totaling 10 values. Therefore, there are 10 original values in the data set that are greater than 50.

The thickness of the clay layer, which drains only from the upper surface, can be determined based on the consolidation settlement observations. With 50% of consolidation settlement occurring in 1 hour for a 25 mm thick specimen, and a total primary consolidation settlement of 35 mm occurring over many years, the thickness of the clay layer is approximately 87.5 mm.

The consolidation settlement of a clay specimen can be used to estimate the thickness of a clay layer that drains only from the upper surface. In this case, the observed settlement data provides valuable information.

Firstly, we know that 50% of the consolidation settlement occurs in 1 hour for a 25 mm thick clay specimen. This is an important parameter for calculating the coefficient of consolidation (Cv) using Terzaghi's theory. From the Cv value, we can estimate the time required for full consolidation settlement.

Secondly, we are given that the same clay settles 10 mm over 10 years and eventually settles a total of 35 mm over a longer period. This long-term settlement is known as the total primary consolidation settlement. By comparing this settlement value with the settlement data from the oedometer test, we can determine the thickness of the clay layer.

To calculate the thickness, we can use the concept of the consolidation settlement ratio. The ratio of the total primary consolidation settlement to the consolidation settlement at 50% completion is equal to the ratio of the total thickness to the thickness at 50% completion. Applying this ratio, we can determine that the thickness of the clay layer, which drains only from the upper surface, is approximately 87.5 mm.

Step-by-step explanation:

The probability that the sample mean exceeds 135.4 millimeters is approximately 0.1446.  

You can use the central limit theorem to approximate the sample distribution of the sample mean.

The mean of the sample distribution is a rise to the population mean (135 mm)

 the standard deviation of the test distribution is a rise to the population standard deviation isolated by the square root of the test measure, which is \(5/√42\) ≈ 0.7689 mm.

To find the probability that the sample mean is greater than 135.4 millimeters, use the sample distribution to standardize the sample mean and use the standard normal distribution. That is,

\(z = (x - μ) / (σ / √n) = (135.4 - 135) / (5 / √42) ≒ 1.0607\)

where x = sample mean, μ = population mean, σ =population standard deviation, n=sample size, and z =standard value.

The probability that the sample mean exceeds 135.4 millimeters can be found by using a standard normal distribution table or calculator,

to find the area to the right of the Z value of 1.0607. This range is approximately 0.1446 or 14.46%.

Therefore, the probability that the sample mean exceeds 135.4 millimeters is approximately 0.1446.

The top of the ladder touches a height of 8 feet on the wall. To determine how high on the wall the top of the ladder touches, we can use the Pythagorean theorem.

In this case, the ladder forms the hypotenuse of a right triangle, and the base of the wall and the height on the wall form the other two sides.

Let's denote the height on the wall as 'h'. According to the problem, one end of the ladder is 6 feet from the base of the wall, so the base of the triangle is 6 feet.

We can set up the equation using the Pythagorean theorem:

\((6)^2 + (h)^2 = (10)^2\)

Simplifying the equation:

36 + \(h^2\) = 100

\(h^2\) = 100 - 36

\(h^2\)= 64

Taking the square root of both sides:

h = √64

Cars with exactly two options = Total cars - Cars with none or one option - Cars with all three options. 8 cars had exactly two of the given options during the month of July.

To determine the number of cars that had exactly two of the given options (air conditioning, automatic transmission, and power steering), we can follow these steps:

1. Find the total number of cars sold in July.
2. Subtract the number of cars with none, one, or all three options to get the number of cars with exactly two options.

Step 1: Find the total number of cars sold in July
- 24 cars had none of the extras
- 24 cars had only air conditioning
- 64 cars had only automatic transmission
- 35 cars had only power steering
- 8 cars had all three extras
Total cars = 24 + 24 + 64 + 35 + 8 = 155 cars

Step 2: Subtract the number of cars with one or all three options
- 87 cars had air conditioning
- 99 cars had an automatic transmission
- 73 cars had power steering
- 8 cars had all three extras

Total cars with at least one option = 87 + 99 + 73 - 8 = 251 cars

Now, subtract the number of cars with none or one option from the total number of cars to find the number of cars with exactly two options:

Cars with exactly two options = Total cars - Cars with none or one option - Cars with all three options
Cars with exactly two options = 155 - (24 + 24 + 64 + 35) - 8 = 155 - 147 = 8 cars

The curve is concave upward on this interval. In interval notation, the answer is:(0, pi/2)

To find dy/dx, we use the chain rule:

dy/dt = -sin(t)

dx/dt = -sin(2t)

Using the chain rule,

dy/dx = dy/dt / dx/dt = -sin(t) / sin(2t)

To find d2y/dx2, we can use the quotient rule:

d2y/dx2 = [(sin(2t) * cos(t)) - (-sin(t) * cos(2t))] / (sin(2t))^2

= [sin(t)cos(2t) - cos(t)sin(2t)] / (sin(2t))^2

= sin(t-2t) / (sin(2t))^2

= -sin(t) / (sin(2t))^2

To determine where the curve is concave upward, we need to find where d2y/dx2 > 0. Since sin(2t) is positive on the interval (0, pi), we can simplify the condition to:

d2y/dx2 = -sin(t) / (sin(2t))^2 > 0

Multiplying both sides by (sin(2t))^2 (which is positive), we get:

-sin(t) < 0

sin(t) > 0

This is true on the interval (0, pi/2). Therefore, the curve is concave upward on this interval.

Position of 103 = 25th term

Step-by-step explanation:

a)

According to the given information:

\( a_3 + 20 = a_8\)

\( a+ (3-1)d + 20 = a+ (8-1)d\)

\( \cancel a+ 2d + 20 = \cancel a + 7d\)

\( 2d + 20 = 7d\)

\( 20 = 7d-2d\)

\( 20 = 5d\)

\( d = \frac{20}{5}\)

\( \purple {\bold {d = 4}} \)

Common difference = 4

b)

\( \because a_3 = 15....(given) \)

\( \therefore a + (3-1)d = 15\)

\( \therefore a + 2d = 15\)

\( \therefore a + 2\times 4= 15\)

\( \therefore a + 8= 15\)

\( \therefore a = 15-8\)

\( \red{\bold {\therefore a = 7}} \)

\( \because a_n = a + (n - 1) d\)

\( \therefore 103 = 7 + (n - 1)4 \)

\( \therefore 103 - 7 = (n - 1)4 \)

\( \therefore 96 = (n - 1)4 \)

\( \therefore \frac{96}{4}= n - 1\)

\( \therefore 24= n - 1\)

\( \therefore 24+1= n\)

\(\blue{\bold {\therefore n = 25}} \)

So, the position of 103 in this sequence is 25th term.

The vector in exact component form is (-6√3, -6).

The given angle is 240° and the magnitude is 12. We will be using the following formula to find out the vector component form. Here are the steps to find the vector component form:
Converting degrees to radians:
We know that 180° is equivalent to π radians.
Therefore,

1° = π/180 radians.
Thus,

240°

= 240 × π/180 radians

= 4π/3 radians.

Identifying the x and y components:
cos θ = x / mag
\(sin θ = y / ma\)
Substituting the given values in the above formulae, we get:
\(cos 240° \\= x / 12sin 240° \\= y / 12x \\= 12 cos 240°\)
\(y = 12 sin 240°\)

Writing the vector in component form:

To find the equation of a line, we need to use the point-slope form, which is given by y - y₁ = m(x - x₁), where (x₁, y₁) represents a point on the line, and m is the slope. In this case, the given point is (-2, 2), and the slope is 2.

Substituting these values into the point-slope form, we get y - 2 = 2(x - (-2)), which simplifies to y - 2 = 2(x + 2). Distributing the 2 on the right side, we have y - 2 = 2x + 4.

To obtain the slope-intercept form of the equation, which is y = mx + b, we isolate y on the left side of the equation. Adding 2 to both sides, we get y = 2x + 6. Therefore, the equation of line L that passes through the point (-2, 2) with a slope of 2 is y = 2x + 6.
