My guess is that what is confusing you is not what you have to do, but why it is disguised as g(n)

What you are doing in effect is setting up a table. You are also not certain where the table starts. And that is a problem. I will start it at zero, but it might be 1.

zero

n = 0

g(0) = 34 - 5*0

g(0) = 34

One

n = 1

g(1) = 34 - 5*1

g(1) = 34 - 5

g(1) = 29

Two

g(2) = 34 - 5*2

g(2) = 34 - 10

g(2) = 24

Three

g(3) = 34 - 5*3

g(3) = 34 - 15

g(3) = 19

Four

g(4) = 34 - 5*4

g(4) = 34 - 20

g(4) = 19

The solution for r is given by \(r=\frac{\sqrt[3]{\frac{3}{2} x} }{\pi }\).

To solve the equation

\(x=(\frac{2}{3} )\pi r^3\) for r,

we need to isolate the variable r.

Let's follow the steps:

Multiply both sides of the equation by \((\frac{3}{2} )\) to cancel out the coefficient \((\frac{2}{3} )\) on the right side:

\((\frac{3}{2} )x=\pi r^3\).

Divide both sides of the equation by π to get rid of it on the right side:

\(\frac{\frac{3}{2} x}{\pi } = r^3\).

Take the cube root of both sides to eliminate the exponent:

\(\sqrt[3]{\frac{3}{2} x} = r\).

Therefore, the solution for r is given by \(r = \frac{\sqrt[3]{\frac{3}{2} x} }{\pi }\).

If speed is important and the array is large, the a. Binary search algorithm should be used. This algorithm is designed to efficiently search through sorted arrays by repeatedly dividing the search interval in half.

It has a time complexity of O(log n), which means that as the size of the array increases, the time it takes to search for an item will not increase at the same rate.
On the other hand, ascending bubble sort and other sorting algorithms such as selection sort and insertion sort have a time complexity of O(n^2), which means that as the size of the array increases, the time it takes to sort the array will increase exponentially. Therefore, these algorithms are not efficient for large arrays and should not be used if speed is important.
In summary, when dealing with large arrays and speed is important, binary search is the best algorithm to use for searching, while ascending bubble sort and other sorting algorithms with a time complexity of O(n^2) should be avoided.

Answer:

g(-2)+h(-3) = -9

Step-by-step explanation:

Given

To determine

Determining g(5)

Given the function

g(x) = x + 4

substitute x = 5

g(5) = 5+4

g(5) = 9

Determining h(6)

Given the function

h(x) = 3x-2

substitute x = 6

h(6) = 3(6) - 2

h(6) = 18-2

h(6) = 16

Determining g(-2)+h(-3)

Given the function

g(x) = x + 4

substitute x = -2

g(-2) = -2 + 4

g(-2) = 2

Given the function

h(x) = 3x-2

substitute x = -3

h(-3) = 3(-3)-2

h(-3) = -9-2

h(-3) = -11

so

g(-2)+h(-3) = 2+(-11)

                 = 2-11

                  = -9

Therefore,

g(-2)+h(-3) = -9

Answer:

Step-by-step explanation:

You are given g(x) = x +4  and  h(x) = 3x-2.

To find g(5), replace x in g(x) = x +4 with 5, obtaining g(5) = 5 + 4 = 9 = g(5)

To find h(6), replace x in h(x) = 3x-2 with 6, obtaining h(6) = 3(6) - 2 =

16 = h(6)

Similarly, g(-2) = -2 + 4 = 2 and h(-3) = -9 - 2 = -11

Then g(-2) + h(-3) = 2 - 11 = - 9 = g(-2) + h(-3)

The value of x and y in the similar triangle are as follows:

x = 30

y = 12

Similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other.

Therefore, let's use the similarity ratio to find the x and y in the triangle as follows:

4x + 2x = 180(sum of angles on a straight line)

6x = 180

divide both sides of the equation by 6

x = 180 / 6

x = 30

Therefore, let's find y. Recall the angles of the similar triangles are congruent.

Therefore,

5y = 60

y = 60 / 5

y = 12

ANSWER

5/10 and 4/10

EXPLANATION

We want to enter fractions given as a pair of fractions that have the same denominator.

The fractions given are:

1/2 and 2/5

To do that, we have to first find the lowest common multiple of the two denominators.

The denominators are:

2 and 5

Their lowest common denominator is 10, since it is the smallest number which is divisible by both numbers.

To put the first fraction in terms of a denominator of 10, we have to multiply the numerator and denominator by 5.

That is:

To put the second fraction in terms of a denominator of 10, we multiply the numberator and denominator by 2.

That is:

Therefore, the two fractions in terms of a common denominator are 5/10 and 4/10.

Find k if (x+1) is a factor of 2x³ + kx² + 1

k = 1

The factor of a polynomial F(x) is another polynomial that divides evenly into F(x). For example, x + 3 is a factor of the polynomial x² - 9.

This is because;

i. x² - 9 can be written as (x - 3)(x + 3) which shows that both (x - 3) and (x + 3) are factors.

ii. If x = -3 is substituted into the polynomial x² - 9, the result gives zero. i.e

=> (-3)² - 9

=> (9) - 9 = 0

Therefore, if (x + a) is a factor of a polynomial, substituting x = -a into the polynomial should result to zero. This also means that, if x - a is a factor of a polynomial, substituting x = a into the polynomial should give zero.

From the question

Given polynomial: 2x³ + kx² + 1

Given factor: x + 1.

Since x + 1 is a factor of the polynomial, substituting x = -1 into the polynomial should give zero and from there we can calculate the value of k. i.e

2(-1)³ + k(-1)² + 1 = 0

2(-1) + k(1) + 1 = 0

-2 + k + 1 = 0

k - 1 = 0

k = 1

Therefore the value of k is 1.

The Vickers hardness (HV) test calculates indentation diagonal length (d) when a load is applied to a material.

To determine d when a 0.700 kg load produces a Vickers HV of 650, use the formula: HV = 1.8544 * (F/d^2), where F is the force in Newtons (N) and d is in mm.
First, convert the load to Newtons: F = 0.700 kg * 9.81 m/s^2 ≈ 6.867 N. Next, rearrange the formula for d: d = √(1.8544 * F/HV). Substituting values: d = √(1.8544 * 6.867 N / 650) ≈ 0.044 mm.
So, the indentation diagonal length (d) is approximately 0.044 mm when a 0.700 kg load produces a Vickers HV of 650.

The solution to the initial value problem is:

y(t) = (-3/4) * e^(-4t+4) + (3/8) * e^(2t+8)

To solve a second-order linear homogeneous differential equation the equation is y′′ 2y′-8y = 0.

Given initial conditions: y(102) = 3 and y′(102) = -12.

To solve this differential equation, we can use the characteristic equation: r^2 + 2r - 8 = 0

Factoring this equation, we get: (r + 4)(r - 2) = 0

So the roots of the characteristic equation are r = -4 and r = 2.

The general solution to the differential equation is:

y(t) = c1 * e^-4t + c2 * e^2t

To find the values of c1 and c2, we can use the initial conditions.

We know that y(102) = 3, so we can substitute t = 2 into the general solution:

3 = c1 * e^-8 + c2 * e^4

We also know that y′(102) = -12, so we can take the derivative of the general solution and substitute t = 2:

y′(t) = -4c1 * e^-4t + 2c2 * e^2t

y′(102) = -4c1 * e^-8 + 2c2 * e^4 = -12

Solving for c1, we get:

c1 = (-3/4) * e^4 + (3/4) * e^-8

Solving for c2, we get:

c2 = (3/8) * e^8 - (3/8) * e^-4

Therefore, the solution to the initial value problem is:

y(t) = (-3/4) * e^(-4t+4) + (3/8) * e^(2t+8)

The 90% confidence interval for the average temperature at which this balloon will be in a steady state of equilibrium is approximately 93.47°C to 100.53°C.

What is a confidence interval?

A confidence interval is a statistical range of values within which an unknown population parameter, such as a mean or a proportion, is estimated to fall with a certain level of confidence. It is a measure of the uncertainty associated with estimating a population parameter based on a sample.

According to the given information:

Based on the given information:

n = 56 (number of readings)

xbar = 97°C (mean temperature)

sigma = 17°C (standard deviation)

c-level = 90% (confidence level)

To compute the 90% confidence interval for the average temperature at which this balloon will be in a steady state of equilibrium, we can use the following formula:

Confidence Interval = xbar ± (Zc * (sigma / sqrt(n)))

where:

xbar is the sample mean

Zc is the critical value corresponding to the desired confidence level (c-level)

sigma is the population standard deviation

n is the sample size

First, we need to find the Zc value for a 90% confidence level. The Zc value can be obtained from a standard normal distribution table or using a calculator or software. For a 90% confidence level, Zc is approximately 1.645.

Plugging in the given values:

xbar = 97°C

Zc = 1.645

sigma = 17°C

n = 56

Confidence Interval = 97 ± (1.645 * (17 / sqrt(56)))

Now we can calculate the confidence interval:

Confidence Interval = 97 ± (1.645 * (17 / sqrt(56)))

Confidence Interval = 97 ± (1.645 * 2.1416)

Confidence Interval = 97 ± 3.5321

Rounding to 2 decimals:

Confidence Interval ≈ (93.47, 100.53)

So, the 90% confidence interval for the average temperature at which this balloon will be in a steady state of equilibrium is approximately 93.47°C to 100.53°C.

1. The equation to slope-intercept form is y = -2/3(x) + 490. The slope is -2/3 and the y-intercept is 490.

2. You should start at the y-intercept (0, 490) and move right by 3 units and downward by 2 units, and then connect the points.

3. The equation in function notation is f(x) = -2/3(x) + 490. The graph of the function is the rate of change with respect to the number of sandwich lunch sold.

4. A graph of the function with intercepts is shown below.

5. The graphs of the functions for the two months both have the same slope but different y-intercept and x-intercept.

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

y = mx + b

Where:

Based on the information provided above, a linear equation that models Sal's Sandwich Shop's profit is given by;

2x + 3y = 1,470

By subtracting 2x from both sides of the equation and dividing by 3, we have:

2x + 3y - 2x = 1,470 - 2x

y = -2/3(x) + 490

Therefore, the slope is -2/3 and the y-intercept is 490.

Part 2.

In order to graph the equation by using the slope-intercept method, you would start at the y-intercept (0, 490) and move right by 3 units and down by 2 units, and then connect the points.

Part 3.

Next, we would write the equation in function notation as follows;

f(x) = -2/3(x) + 490

where:

The graph represents the rate of change of the function with respect to the number of sandwich lunch sold.

Part 4.

In this context, we would use an online graphing calculator to plot the linear function as shown in the image attached below.

Part 5.

Assuming Sal's total profit on lunch specials for the next month is $1,593 and the profit amounts remain the same, a system of equations to model this situation is given by:

2x + 3y = 1593; y = -2/3(x) + 531.

2x + 3y = 1,470; y = -2/3(x) + 490.

In conclusion, we can logically deduce that the graphs of the functions for the two months both have the same slope but different y-intercept and x-intercept.

This is an example of a sample survey or a sampling method.

Sampling techniques in a statistical study refer to how participants are chosen from the population to participate in the study. If a sample isn't chosen at random, it will likely be skewed in some way, and the results might not be generalizable.

In the given scenario, you are conducting a sample survey to determine the proportion of each color of Peanut Butter M&Ms. A sample survey is a method used to collect data from a subset of a larger population in order to make inferences about the entire population.

Instead of counting every single Peanut Butter M&M in existence, which would be impractical and time-consuming, you decide to take a smaller representative sample. You purchase 10 packages of Peanut Butter M&Ms, each weighing 1.69 ounces, and count the number of M&Ms of each color in those packages.

By analyzing the data collected from this sample, you can estimate the proportion of each color of Peanut Butter M&Ms in the larger population. This approach is more feasible and provides a reasonable approximation of the overall distribution of colors without having to examine every individual item.
