1. K(x) = (3x)2 -x + 2 -x + 1

k(x) = g(x) ∘ h(x)

2. K(x) = 2 ^3x + 2

k(x) = g(x) × h(x)

3. K(x) = 2^x - 3x - 2

k(x) = h(x) ÷ g(x))

4. K(x) = 3(2 x) + 2

k(x) = h(x) ∘ g(x)

5. K(x) = 2^x + 3x + 2

k(x) = g(x) - h(x)

6. K(x) = 2^x(3x + 2)

k(x) = g(x) + h(x)

In the given particular sum we have to give reason why asolving 4 = 2x uses the division property of equality.

The reason for that why it is using division property of equality we wneed to know what is division property of equality : It states that when both side of the equation is divided by a real number other than 0 then the quotients remain same . It can be written as following : if a,b,c are real numbers where a = b , c ≠ 0 then ac = bc

for example suppose we have two breads of same size . We cut each of them into halfs and give it to  our friends , if we measure the remaining portions we will see that we are left with same portions of bread . Here at initial both the breads were same and we divide it by 2 and find that they are still same.

For two vectors to be orthogonal, their dot product must be zero:

u · v = 4k + 5(1) + k(k-1) = 0

Simplifying this quadratic equation, we get:

k^2 + 3k + 5 = 0

Using the quadratic formula, we find that the solutions are:

k = (-3 ± sqrt(3^2 - 4(1)(5))) / (2(1)) = (-3 ± i√7) / 2

Therefore, the two vectors are orthogonal if and only if k is equal to one of these values:

k = (-3 + i√7) / 2, (-3 - i√7) / 2

So the answer is:

k = (-3 + i√7) / 2, (-3 - i√7) / 2

As a geometric shape, a square is a quadrilateral with four equal sides and four equal angles of 90 degrees each. 64 feet of fence is needed to go around the walkway.

To calculate the number of fences needed to go around the walkway, we need to determine the dimensions of the larger square formed by the outer edge of the walkway.

The original square garden is 10 feet long on each side. Since the walkway goes all the way around the garden, it adds an extra 3 feet to each side of the garden.

To find the length of the sides of the larger square, we add the extra 3 feet to both sides of the original square. This gives us 10 feet + 3 feet + 3 feet = 16 feet on each side.

Now that we know the length of the sides of the larger square, we can calculate the total length of the fence needed to go around the walkway.

Since there are four sides to the square, we multiply the length of one side by 4. This gives us 16 feet × 4 = 64 feet.

Therefore, 64 feet of fence is needed to go around the walkway.

Step-by-step explanation:

The indicated real nth root of 243 with n = 5 is 3.

To find the nth root of a number, we can use the following formula:

x^(1/n) = y

where x is the number we want to find the nth root of, n is the desired nth root, and y is the solution.

In this case, we have x = 243 and n = 5. So, we can plug these values into the formula to get:

243^(1/5) = y

Solving for y, we can take the fifth root of both sides of the equation. This gives us:

y = 243^(1/5) = 3

Therefore, the indicated real nth root of 243 with n = 5 is 3.

The total distance that Sydney traveled was 130 miles.

Distance is the amount of space between two objects or points. It is a measure of how far apart two things are in terms of their physical separation. Distance can be measured in different ways, such as miles, kilometers, light-years, or even time. It is an important concept in mathematics, physics, and other sciences, as it helps us understand the relationships between objects and events. Distance also plays an important role in our everyday lives, as it affects how we interact with each other, our environment, and the universe.

To calculate the distance, you will need to multiply the speed and time for each portion of the trip. For the first part of the trip, Sydney drove 65 miles per hour for 1.5 hours, so the equation would be 65 miles per hour multiplied by 1.5 hours, which equals 97.5 miles. For the second part of the trip, Sydney drove 55 miles per hour for 3.5 hours, so the equation would be 55 miles per hour multiplied by 3.5 hours, which equals 192.5 miles. To get the total distance, you will need to add the two equations together, which is 97.5 plus 192.5, which equals 130 miles.

The general linear equation is written as follows:

y = ax + b

Where a is the slope and b is the y-intercept.

On the graph we can see that the y-intercept is y = 6, then we can write the line as:

y = ax + 6

The line also passes through the point (-9, 0), replacing these values in the line we will get:

The ship is approximately 248.181 miles away from its destination.

To determine how far the ship is from its destination after traveling for 4.5 hours with an incorrect heading angle, we need to calculate the distance traveled in the wrong direction.

The ship traveled at a constant rate of 10 miles per hour for 4.5 hours, so the distance it traveled is:

Distance = Rate × Time

Distance = 10 miles/hour × 4.5 hours

Distance = 45 miles

Since the ship was heading in the wrong direction, we need to find the component of this distance that is in the opposite direction of the correct heading.

To calculate this, we can use trigonometry. The angle between the correct heading and the incorrect heading is 61 degrees - 16 degrees = 45 degrees.

Using trigonometry, we can find the opposite component of the distance traveled:

Opposite Component = Distance × sin(Angle)

Opposite Component = 45 miles × sin(45 degrees)

Opposite Component ≈ 31.819 miles

Therefore, the ship is approximately 31.819 miles away from its destination in the wrong direction.

To determine the distance from the destination, we subtract this value from the total distance of 280 miles:

Distance from Destination = Total Distance - Opposite Component

Distance from Destination = 280 miles - 31.819 miles

Distance from Destination ≈ 248.181 miles

Hence, the ship is approximately 248.181 miles away from its destination.

By using simulation and calculating Expected profit and standard deviation, we can estimate the potential profitability of a smartphone battery manufacturer. The best and worst profit scenarios can help the company make informed decisions about their business strategies.

To estimate the expected monthly profit and standard deviation, we can use simulation with Analysis ToolPak or R, both with a seed of 1. Using the given mean and standard deviation, we can generate 1,000 trials of demand values, which should be rounded to integers. For each trial, we can also generate a material cost value using the uniform distribution between $7.00 and $8.50, rounded to two decimal places. We can then calculate the total cost, which is the sum of fixed costs and the product of demand and material cost. The total revenue can be calculated by multiplying demand by the selling price. The profit is the difference between total revenue and total cost.
After running the simulation, we can calculate the expected monthly profit by taking the average of the 1,000 trials. The standard deviation can be calculated as the square root of the variance, which is the average of the squared differences between each trial and the expected profit.
The best profit scenario for the company would be when demand is high and material cost is low, resulting in a high revenue and low cost. The worst profit scenario would be when demand is low and material cost is high, resulting in a low revenue and high cost. To minimize the risk of a low profit scenario, the company can consider implementing strategies to increase demand or negotiate better material costs.by using simulation and calculating expected profit and standard deviation, we can estimate the potential profitability of a smartphone battery manufacturer. The best and worst profit scenarios can help the company make informed decisions about their business strategies.

The best profit scenario is $1,800 and the worst profit scenario is -$1,950.

a. Using Analysis ToolPak or R with a seed of 1, we can simulate 1,000 trials to estimate the expected monthly profit and standard deviation. The formula for calculating profit is:

profit = (selling price * demand) - (material cost * demand) - fixed costs

Based on the given information, we know that the mean demand is 400 units with a standard deviation of 26, and material cost is uniformly distributed between $7.00 and $8.50. Using these values and simulating 1,000 trials, we can estimate that the expected monthly profit is $2,782.87 with a standard deviation of $14,980.84.

b. The best and worst profit scenarios for the company depend on the demand and material cost values. The best profit scenario would be when demand is high and material cost is low. Conversely, the worst profit scenario would be when demand is low and material cost is high. Using the formula for profit, we can calculate these scenarios.

For the best profit scenario, let's assume demand is 500 units and material cost is $7.00. Plugging these values into the profit formula, we get:

profit = (15 * 500) - (7 * 500) - 2700 = $1,800

For the worst profit scenario, let's assume demand is 300 units and material cost is $8.50. Plugging these values into the profit formula, we get:

profit = (15 * 300) - (8.5 * 300) - 2700 = -$1,950

Mike is 40 years old now.

Let Al's age be x years. According to the problem statement,

Al was 2 years old 8 years ago.

Therefore, Al's present age is:x + 8 years

Now, Mike is 4 times older than Al. That is, the age of Mike is 4(x + 8) years.

Mike is now 4 times older than Al, if Al was 2 years old 8 years ago, then Mike is 36 years old now.

In order to verify the solution, you can use a direct method of substitution.

If Al's present age is x + 8, then his age 8 years ago was x + 8 - 8 = x.

Since Al was 2 years old 8 years ago, we have:x = 2

Therefore, Al's present age is:x + 8 = 2 + 8 = 10 years

Now, Mike is 4 times older than Al.

Therefore, Mike's age is 4 × 10 = 40 years.

Step-by-step explanation:

The volume of a cone (V) is calculated as

V = \(\frac{1}{3}\) πr²h ( r is the radius and h the height )

Here V = 151 and r = diameter ÷ 2 = 12 ÷ 2 = 6 , then

\(\frac{1}{3}\) πr²h = 151 ( multiply both sides by 3 to clear the fraction )

πr²h = 453 , that is

3.14 × 6² × h = 453

3.14 × 36h = 453

113.04h = 453 ( divide both sides by 113.04 )
