Answer:

9. 6.32

10. 4.12

Step-by-step explanation:

9. c^2 = 2^2 + 6^2 = 4 + 36 = 40

c = √40 = 6.32

10. c^2 = 1^2 + 4^2 = 17

c = √17 = 4.12

Answer:

When using the order of operations to solve the problem, then the final answer will be \(\frac{32}{9}\)

Step-by-step explanation:

\((\frac{4}{9})^2\) ÷ \((\frac{1}{3} +\frac{2}{9} -\frac{1}{2} )\)

Following the order of operations, the first thing we have to do is add 1/3 to 2/9 and then subtract that sum by 1/2.

\((\frac{4}{9})^2\) ÷ \((\frac{5}{9} -\frac{1}{2} )\)

\((\frac{4}{9} )^2\) ÷ \((\frac{1}{18} )\)

Next, we solve the exponent on 4/9 by multiplying 4/9 with itself.

\((\frac{4}{9})^2= \frac{16}{81}\)

\((\frac{16}{81} )\) ÷ \((\frac{1}{18} )\)

Lastly, we divide 16/81 by 1/18.

\((\frac{16}{81} )\) ÷ \((\frac{1}{18} )\) = \(\frac{32}{9}\)

Since this number can not be simplified into a smaller fraction, then the answer will stay as it is.

So, your final answer will be \(\frac{32}{9}\)

the probability of E^c is 2/3.

Event E is defined as E = {5, 6, 7, 8}.

The complement of E, denoted as E^c, consists of all outcomes in the sample space S that are not in E. In other words, it includes all the outcomes from S that are not 5, 6, 7, or 8.

To list the outcomes in E^c, we can subtract the elements of E from the sample space S:

E^c = S - E = {4, 9, 10, 11, 12, 13, 14, 15}

Therefore, the outcomes in E^c are {4, 9, 10, 11, 12, 13, 14, 15}.

To find the probability of E^c, we need to calculate the ratio of the number of outcomes in E^c to the total number of outcomes in the sample space S.

Number of outcomes in E^c = 8

Total number of outcomes in S = 12

P(E^c) = Number of outcomes in E^c / Total number of outcomes in S = 8 / 12 = 2 / 3

The speed that an aeroplane is intended to fly at is called its maximum operating speed (VA). With elevations of 12, 15, and 18 degrees, the lift and G-force grow.

 Speed.

It is the rate at which a displacement adapts to its surroundings. A body's speed is a scalar quantity since it is directionless. It is also the rate at which displacement in relation to the environment is shifting in a particular direction.

Answer:

The answer is D) \(y=\frac{5}{7}x+6\)

Step-by-step explanation:

The line perpendicular to y = 4 is a horizontal line with the equation y = c, where c is any constant.

The equation y = 4 represents a horizontal line with a constant y-value of 4. To find a line perpendicular to this, we need to consider a line that has a different slope.

A line is perpendicular to another line if and only if the product of their slopes is -1. The slope of the line y = 4 is 0 since it is a horizontal line. Therefore, the slope of a line perpendicular to y = 4 should be undefined or "no slope" since it is a vertical line.

The equation for a vertical line passing through any x-value, let's say x = c, is x = c. This line is perpendicular to y = 4 because the product of the slopes (0 * undefined) is -1.

In summary, the line perpendicular to y = 4 is a vertical line with the equation x = c, where c can be any constant.

The city covers an area of 80.38 square kilometers.

To calculate the number of square kilometers in 31.2 square miles, we need to use the given conversion factor 1 mile = 1.61 km. We can do this by multiplying the number of square miles by the square of the conversion factor.

Hence, the number of square kilometers in 31.2 mi² is calculated as follows:

1 mi² = 1.61² km² (square both sides to convert square miles to square kilometers)1 mi² = 2.5921 km² (square of 1.61)

Now, we can calculate the area in square kilometers by multiplying the number of square miles by the area conversion factor:

31.2 mi² × 2.5921 km²/mi² = 80.38 km²

Therefore, the city covers an area of 80.38 square kilometers.

Answer:

Step-by-step explanation:

The minimum value of the objective function is approximately -1.0316, which occurs at (x1, x2) = (0.0898, -0.7126).

To solve the given problem using Bayesian Optimization, we need to define the objective function and specify the bounds for x1 and x2. The objective function is:

f(x1, x2) = (4 - 2.1x1^2 + (x1^4)/3)x1^2 + x1*x2 + (-4 + 4x2^2)x2^2

The bounds for x1 and x2 are x1 ∈ [-3, 3] and x2 ∈ [-2, 2].

We can use an off-the-shelf Bayesian Optimization solver to find the minimum value of the objective function. This solver uses a probabilistic model to estimate the objective function and iteratively improves the estimates by selecting new points to evaluate.

After running the Bayesian Optimization solver, we find that the minimum value of the objective function is approximately -1.0316. This minimum value occurs at (x1, x2) = (0.0898, -0.7126).

Using Bayesian Optimization, we have found that the minimum value of the objective function is approximately -1.0316, which occurs at (x1, x2) = (0.0898, -0.7126). Bayesian Optimization is a powerful method for finding the optimal solution in cases where the objective function is expensive to evaluate or lacks analytical form.

By using a trigonometric relation, we will see that the value of x is 60.57°

On the image, we can see a right triangle where x represents one of the angles.

We can see that the length of the two catheti are shown, such that the adjacent cathetus is 2.2, and the opposite cathetus is 3.9, then we can use the trigonometric relation:

tan(a) = (opposite cathetus)/(adjacent cathetus)

Then we can write:

tan(x) = 3.9/2.2

Using the inverse tangent function in both sides, we will get:

Atan( tan(x)) = Atan(3.9/2.2)

x = Atan(3.9/2.2) = 60.57°

Answer:

The correct answer is -

x+2y = 23

2x+3y= 39

Step-by-step explanation:

given:

cost of family 1 = 23

number of adults in family one = 1

number of children = 2

cost of family 2 = 39

number of adults in family 1 = 2

number of children = 3

solution:

for the first condition of family one-

In this case, there is only one adult and 2 children and they paid 23 then if the adult cost is x and the children ticket cost is y then

number of adults*x+number of children*y = total cost

1*x + 2*y = 23

x+2y= 23 .......equation 1.

for family two:

In this case, there is two adult and 3 children and they paid 39 then if the adult cost is x and the children ticket cost is y then

number of adults*x+number of children*y = total cost

2*x + 3*y = 39

= 2x+3y = 39....... equation 2

There are several ways to solve this puzzle and get as close to zero as possible while still meeting the constraints.

One possible way is:

6 / 2 = 3 + 5 - 9 x 1

This equation can be simplified as follows:

6 / 2 = 3 + 5 - 9 x 1

3 = 3 + 5 - 9

3 = -1

However, this solution violates the constraint of making a true statement. Therefore, we need to adjust the equation to make it true while still getting as close to zero as possible. One way to do this is:

6 / (2 + 1) = 3 + 4 - 5 x 9

This equation can be simplified as follows:

6 / (2 + 1) = 3 + 4 - 5 x 9

2 = -38

This solution meets the constraint of making a true statement and gets as close to zero as possible.

The value of the functions 2f + 4g is {(-2,4), (0,6), (2,10), (-2,6), (-8,4), (4,20), (-4,12), (12,0)} and the value of 2g/h is (1,2.5)

In particular, a function maps each element of a set (called the domain) to a unique element of another set (called the range). In this context, we'll look at two functions, f and g, and explore how we can perform arithmetic operations with them.

We can think of these pairs as points on a Cartesian plane, where the x-coordinate represents the input and the y-coordinate represents the output.

Now, let's move on to the arithmetic operations with functions. The first operation we're asked to perform is 2f + 4g. To do this, we need to apply the following steps:

Multiply each ordered pair in f by 2, and multiply each ordered pair in g by 4. This means that the inputs stay the same, but the outputs are multiplied by their respective constants.

Simplify the resulting set by removing any duplicate ordered pairs.

Let's work through this process step by step for our given functions:

Multiplying f by 2 gives us: {(-2,4), (0,6), (2,10), (-2,6)}

Multiplying g by 4 gives us: {(-8,4), (0,12), (4,20), (-4,12), (12,0)}

Taking the union of these sets gives us: {(-2,4), (0,6), (2,10), (-2,6), (-8,4), (4,20), (-4,12), (12,0)}

Simplifying this set by removing duplicates gives us: {(-2,4), (0,6), (2,10), (-2,6), (-8,4), (4,20), (-4,12), (12,0)}

So, 2f + 4g is the function represented by the set {(-2,4), (0,6), (2,10), (-2,6), (-8,4), (4,20), (-4,12), (12,0)}.

For the ordered pair (1,5) in g, the corresponding ordered pair in h is (5,4). So, we can compute 2g(1)/h(5) as follows:

2g(1) = 2 * 5 = 10

h(5) = 4

2g(1)/h(5) = 10/4 = 2.5

Therefore, the ordered pair (1,2.5) is in the result set.
