Answer: Its A and D

Step-by-step explanation:

Answer:

1) The volume of the frustum is 27·(√3)·h

2) The surface area the frustum is 24·h + 54·√3

Step-by-step explanation:

1) A frustum of the regular triangular prism is a portion of the triangular prism

The length of the edge of the triangle prism = 12

The area of the triangular face, A = (√3/4)·a²

∴ A = (√3/4)·12² = 36·√3

When

The volume of the triangular prism, V = A·h = (36·√3)·h

By triangle proportionality theorem, the cross sectional area of the top half of the triangular prism =  (√3/4)·6² = 9·(√3)

The volume of the top half, V₂ = 9·(√3)·h

The volume of the frustum = V - V₂ = (36·√3)·h - 9·(√3)·h = 27·(√3)·h

The volume of the frustum = 27·(√3)·h

2) The surface area of the triangular side of the frustum is given as follows;

A = 36·√3- 9·(√3) = 27·(√3)

The surface area the frustum, \(F_A\) = 2×27·(√3) + 2 ×6 ×h + 12×h = 24·h + 54·√3

The surface area the frustum = 24·h + 54·√3

Step-by-step explanation:

Adding 10 to both sides of the original equation gets us q = 6(r + 1) + 10. Since q is equal to h(r), we get h(r) = 6(r + 1) + 10 = 6r + 16.

Your sister is using the "shadow and similar triangles" method to approximate the height of the rock wall. By setting up a proportion between the vertical and horizontal distances, she can find the height of the wall. Her approximation in this case is 66 inches.

Your sister is using a method called "shadow and similar triangles" to approximate the height of the rock wall. This method involves using the ratios of corresponding sides of similar triangles to find unknown measurements.

Let's break down the problem step by step:

Convert the measurements to a consistent unit:

The horizontal distance from your sister to the rock wall is 13 feet 5 inches. Convert this to inches: 13 feet × 12 inches/foot + 5 inches = 157 inches.

The vertical distance from the ground to her eyes is 5 feet 6 inches. Convert this to inches: 5 feet × 12 inches/foot + 6 inches = 66 inches.

Set up the proportion using the similar triangles:

Let h represent the height of the rock wall.

We can set up the proportion: (height of the wall)/(vertical distance) = (horizontal distance)/(distance to the wall)

h/66 = 157/157

h/66 = 1

Solve for the height of the rock wall:

Cross-multiply the proportion: h = 66 × 1

The values of function being changed according to the recursive formulae  a) f(1) = -6, f(2) = 12, f(3) = -24, f(4) = 48, and f(5) = -96, b)  f(1) = 16, f(2) = 55, f(3) = 172, f(4) = 523, and f(5) = 1576, c) f(1) = 1, f(2) = -3, f(3) = 13, f(4) = 141, and f(5) = 19597.

Let's find the values of f(1), f(2), f(3), f(4), and f(5) for each of the given recursive definitions:

(a) f(n+1) = -2f(n)

Using this recursive formula, we can calculate the values as follows:

f(1) = -2f(0) = -2(3) = -6

f(2) = -2f(1) = -2(-6) = 12

f(3) = -2f(2) = -2(12) = -24

f(4) = -2f(3) = -2(-24) = 48

f(5) = -2f(4) = -2(48) = -96

Therefore, f(1) = -6, f(2) = 12, f(3) = -24, f(4) = 48, and f(5) = -96.

(b) f(n+1) = 3f(n) + 7

Using this recursive formula, we can calculate the values as follows:

f(1) = 3f(0) + 7 = 3(3) + 7 = 9 + 7 = 16

f(2) = 3f(1) + 7 = 3(16) + 7 = 48 + 7 = 55

f(3) = 3f(2) + 7 = 3(55) + 7 = 165 + 7 = 172

f(4) = 3f(3) + 7 = 3(172) + 7 = 516 + 7 = 523

f(5) = 3f(4) + 7 = 3(523) + 7 = 1569 + 7 = 1576

Therefore, f(1) = 16, f(2) = 55, f(3) = 172, f(4) = 523, and f(5) = 1576.

(c) f(n+1) = f(n)² – 2f(n) – 2

Using this recursive formula, we can calculate the values as follows:

f(1) = f(0)²  - 2f(0) - 2 = 3²  - 2(3) - 2 = 9 - 6 - 2 = 1

f(2) = f(1)²  - 2f(1) - 2 = 1²  - 2(1) - 2 = 1 - 2 - 2 = -3

f(3) = f(2)²  - 2f(2) - 2 = (-3)²  - 2(-3) - 2 = 9 + 6 - 2 = 13

f(4) = f(3)²  - 2f(3) - 2 = 13²  - 2(13) - 2 = 169 - 26 - 2 = 141

f(5) = f(4)²  - 2f(4) - 2 = 141²  - 2(141) - 2 = 19881 - 282 - 2 = 19597

Therefore, f(1) = 1, f(2) = -3, f(3) = 13, f(4) = 141, and f(5) = 19597.

Therefore, The values of function being changed according to thr recursive formulae a) f(1) = -6, f(2) = 12, f(3) = -24, f(4) = 48, and f(5) = -96, b)  f(1) = 16, f(2) = 55, f(3) = 172, f(4) = 523, and f(5) = 1576, c) f(1) = 1, f(2) = -3, f(3) = 13, f(4) = 141, and f(5) = 19597.

when you are interrogating the external validity of a sample, option(b). how was the sample collected? is the most important question to ask.

What is External validity?

The concept of external validity is related to the concept of generalization. It's imperative to keep that in mind. It is important to remember that validity refers to the approximate truth of a proposition, an inference, or a conclusion. In other words, external validity refers to the relative truth of generalizations based on generalizations. The external validity of your study is the degree to which the conclusions are applicable to other people, places, and times.

An external validity threat is an explanation of how a generalization could be flawed. A study you conducted in a particular place, with certain types of people, at a particular time, can be generalized to another context (for instance, another place, with slightly different people, at a slightly different time). External validity can be compromised in three ways: people, places, and times.

The ordered pair (1, 2) is a solution to the system of inequalities

x + y > 2 and

3x + 2y ≤ 6.

To find an ordered pair that is a solution to the system of inequalities:

Start with the first inequality:

x + y > 2.

Choose a value for x and y that satisfies this inequality. For example, let's choose

x = 1 and

y = 2.

Substituting these values into the inequality:

1 + 2 > 2, which is true.

Now, let's move to the second inequality:

3x + 2y ≤ 6.

Substitute the same values, x = 1 and

y = 2, into this inequality:

3(1) + 2(2) ≤ 6.

Simplifying, we have:

3 + 4 ≤ 6, which is true.

Therefore, the ordered pair (1, 2) is a solution to the given system of inequalities.

True. In 2016, the percentage of the ageing population (55 years or older) in state prisons surpassed the percentage of people aged 18-24 for the first time.

This trend reflects the overall growth of the ageing population within the United States and is a result of various factors such as longer life expectancy, harsher sentencing laws, and an increase in older individuals being convicted of crimes.
As the ageing population in state prisons continues to grow, it poses several challenges for the correctional system. These challenges include providing appropriate healthcare and accommodations for older inmates and addressing the specific needs of this population, such as mobility assistance and specialized medical care.
In conclusion, the shift in the age demographics of state prisons has significant implications for the management and administration of correctional facilities. It is crucial to address the unique needs of the ageing population within these institutions and adapt policies and practices accordingly to ensure the well-being and fair treatment of all inmates, regardless of their age.

Arthur and George are travelling in the same direction, but George was already 12 kilometers ahead of Arthur.

This is because George's speed is slower than Arthur's. Arthur's speed is 4 km/h, and George's speed is 3 km/h. Therefore, Arthur is able to catch up with George.Arthur would have to cover the distance George had already covered, plus the 12 kilometers between them.

The distance Arthur has to cover to catch up with George is given by:

Distance = 12 km + distance George covered Arthur's speed = 4 km/hGeorge's speed = 3 km/hTime taken to catch up is given by:Time = Distance / Speed = (12 km + distance George covered) / (4 km/h - 3 km/h) = (12 km + distance George covered) / 1 km/h

Answer:

10/3 and mixed fraction is 3 1/3

Step-by-step explanation:

If the total degrees of freedom (dftotal) in an analysis of variance comparing three treatment conditions is 32, the group size for each condition needs to be determined.



To determine the number of individuals in each group, we need to divide the total number of individuals (dftotal) by the number of treatment conditions (groups).

Given that dftotal = 32 and there are three treatment conditions (groups), we can divide dftotal by the number of treatment conditions to find the number of individuals in each group.

Number of individuals in each group = dftotal / number of treatment conditions

Number of individuals in each group = 32 / 3

Number of individuals in each group ≈ 10.67

Since the groups must have the same size, we need to round the result to the nearest whole number. Therefore, there are approximately 11 individuals in each group.

Farmer Ed has 3,000 meters of fencing and wants to enclose a rectangular plot that borders on a river.The largest area that can be enclosed is 750,000 square meters.

To get the largest area that can be enclosed, we have to find the dimensions of the rectangular plot. Let's assume that the width of the rectangle is x meters.The length of the rectangle can be found by subtracting the width from the total length of fencing available:L = 3000 - x. The area of the rectangle can be found by multiplying the length and width:Area = L × W = (3000 - x) × x = 3000x - x²To find the maximum value of the area, we can differentiate the area equation with respect to x and set it equal to zero.

Then we can solve for x: dA/dx = 3000 - 2x = 0x = 1500. This means that the width of the rectangle is 1500 meters and the length is 3000 - 1500 = 1500 meters.The area of the rectangle is therefore: Area = L × W = (3000 - 1500) × 1500 = 750,000 square meters. So the largest area that can be enclosed is 750,000 square meters.
