The length of the missing leg is √29 units

Given that c=5 km and b=2 km

We have to find the value of a

The length of the missing leg is a which is hypotenuse which we have to find.

c²+b²=a²

5² + 2² =a²

25+4=a²

29=a²

Square root on both sides

a=√29 units

Hence, the length of the missing leg is √29 units

The other two angle of rotation that connect A and B are 3π/4 radians and -13π/4 radians

To rotate point A to point B, we are rotating -5π/4 radians counterclockwise from the positive x-axis. To find two other angles of rotation that take A to B, we can add or subtract multiples of 2π radians, since this will result in a full revolution around the unit circle.

First, to find a negative angle of rotation that takes A to B, we can subtract 2π radians from -5π/4 radians:

-5π/4 - 2π = -13π/4

This tells us that rotating point A -13π/4 radians (or 3π/4 radians clockwise) will take it to point B.

Next, to find a positive angle of rotation that takes A to B, we can add 2π radians to -5π/4 radians:

-5π/4 + 2π = 3π/4

This tells us that rotating point A 3π/4 radians counterclockwise will take it to point B.

Therefore, the other two angle of rotation that connect A and B are 3π/4 radians and -13π/4 radians

Consider the function f(x) = (x² - 4)/(x - 2).

For x gives us x = -2 and x = 2 which are the x-intercepts of f(x) and we have f(0) = -4/2 = -2 which is the y-intercept of f(x)

What is meant by function?

A function is a mathematical rule that assigns a unique output value for each input value in a specified domain. It is a relationship between two or more variables that describes how one variable depends on the others.

What is meant by the x-intercept?

The x-intercept of a function is the point where the graph of the function intersects the x-axis. It is the value of the input variable (usually denoted as x) that makes the output of the function equal to zero.

According to the given information

Consider the function f(x) = (x² - 4)/(x - 2). To find the x-intercept, we set f(x) = 0 and solve for x. We get (x² - 4)/(x - 2) = 0 which means that x² - 4 = 0 since division by zero is undefined. Solving for x gives us x = -2 and x = 2 which are the x-intercepts of f(x). To find the y-intercept, we set x = 0 and solve for y. We get f(0) = -4/2 = -2 which is the y-intercept of f(x)

The complete question is:

For this rational function, Use algebra to find the x-intercepts and

The estimated values of a and b are given below:

The probability of Type I error (false positive) is denoted by a.

The probability of Type II error (false negative) is denoted by b.

Data provided:

In 6,500 computer sessions with no intrusions, only 13 resulted in a false alarm.

Hence, the probability of a false alarm is 13/6,500 = 0.002.

Therefore, the estimated value of a = 0.002

Only 500 were detected out of 2,000 intrusions.

Hence, the probability of a missed detection is (2,000 - 500)/2,000 = 0.75.

Answer:

1. Let’s assume that the original garden was a rectangle with width w and length l. After extending it by equal length on two sides, we get a new rectangle with width w+2x and length l+2x. The area of the new rectangle is (w+2x)(l+2x). To find the area of the extended area only, we need to subtract the area of the original garden from the area of the new rectangle. The area of the original garden is wl. Therefore, the polynomial that represents how much square foot of soil you need to cover the extended area only is:

(w+2x)(l+2x) - wl

which can be simplified as:

wl + 2lx + 2wx + 4x^2 - wl

The polynomial can be further simplified as:

4x^2 + 2lx + 2wx

2. If the original garden was extended by 6 ft on each side, then the new garden will be extended by 175% 1.

To calculate this percentage, we can use the formula:

% increase = (new value - old value) / old value * 100%

The original garden has an area of 64 square feet (8 feet x 8 feet). If we extend each side by 6 feet, then the new garden will have an area of 196 square feet (14 feet x 14 feet).

So, using the formula above:

% increase = (196 - 64) / 64 * 100%

% increase = 132 / 64 * 100%

% increase = 206.25%

Therefore, if the original garden was extended by 6 ft on each side, then the new garden will be extended by 206.25% 1.

The only ordered pair that is a solution to the given system of inequalities is (0, -1).

Inequalities are mathematical statements that describe a relationship between two values or expressions that are not necessarily equal. In an inequality, the symbols "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to) are used to indicate the relationship between the expressions.

In the given questions,

To determine if an ordered pair is a solution to a system of inequalities, we must check if the pair satisfies all the inequalities in the system.

For the given system of inequalities:

y < -x² + x

y > x² - 4

Checking each of the given ordered pairs:

(0, -1):

-1 < -0² + 0 is true

-1 > 0² - 4 is true

So, (0, -1) is a solution to the system of inequalities.

(1, 1):

1 < -1² + 1 is false

1 > 1² - 4 is true

So, (1, 1) is not a solution to the system of inequalities.

(2, -3):

-3 < -2² + 2 is true

-3 > 2² - 4 is false

So, (2, -3) is not a solution to the system of inequalities.

(3, -6):

-6 < -3² + 3 is false

-6 > 3² - 4 is false

So, (3, -6) is not a solution to the system of inequalities.

The values of the trigonometry ratios are sin(21) = √(1 -  k²), cos(201) = -k,  cos(42) = 2k² + 1 and cos(51) = k√3/2 - 1/2√(1 -  k²)

Given that cos 21° =k

Next, we calculate the trigonometry ratios as follows

(1) sin 21°

Here, we use

sin²(x) + cos²(x) = 1

So, we have

sin²(21) + cos²(21) = 1

This gives

sin²(21) + k² = 1

By subtraction, we have

sin²(21) = 1 -  k²

Take the square roots

sin(21) = √(1 -  k²)

(2) cos 201⁰

This is calculated using

cos(a + b) = cos(a)cos(b) - sin(a)sin(b)

So, we have

cos(180 + 21) = cos(180)cos(21) - sin(180)sin(21)

Evaluate the ratios

cos(201) = -1 * k - 0 * √(1 -  k²)

So, we have

cos(201) = -k

(3) cos 42°

Here, we have

cos(a + a) = cos²(a) - sin²(a)

So, we have

cos(21 + 21) = cos²(21) - sin²(21)

Evaluate the ratios

cos(42) = k² + 1 +  k²

So, we have

cos(42) = 2k² + 1

(4) cos 51°

This is calculated using

cos(a + b) = cos(a)cos(b) - sin(a)sin(b)

So, we have

cos(30 + 21) = cos(30)cos(21) - sin(30)sin(21)

Evaluate the ratios

cos(51) = √3/2 * k - 1/2 * √(1 -  k²)

So, we have

cos(51) = k√3/2 - 1/2√(1 -  k²)

For this question you can use simultaneous equation, both elimination method or substitution method. In math when you are trying to solve for something but you don't have the answer to it, you can always use x.

soooo
5x + 3y = 27 (equation 1)

7x + 9y = 51 (equation 2)

soo im using substitution method

From equation 1, we can solve for y in terms of x:

y = (27 - 5x) / 3

Substitute this expression for y into equation 2 and solve for x:

7x + 9[(27 - 5x) / 3] = 51

Multiplying both sides by 3 to eliminate the fraction:

21x + 27 - 15x = 153

Simplifying and solving for x:

6x = 126

x = 21

Now, we can substitute this value for x into either equation 1 or equation 2 to solve for y:

5(21) + 3y = 27

105 + 3y = 27

3y = -78

y = -26

The two types of interest computations utilised in finance are simple interest and compound interest.

Simple interest is just computed on the principal, or the initial amount borrowed or invested. For a specific amount of time, the interest rate is applied to the principal sum, and each period's interest earned or charged is the same.

On the other hand, compound interest is calculated using both the original principal and any prior interest payments. The principal is increased by the interest generated in each month, and the new sum serves as the foundation for computing interest in the following period.

The compound interest is given by the formula:

[tex]A = P(1 + r/n)^{(nt)}[/tex]

Isolating the value of P we have:

[tex]P = A/(1 + r/n)^{(nt)}[/tex]

Now, substituting the values A = $40,000, r = 0.06 (6% as a decimal), n = 2 (compounded semi-annually), and t = 18 years:

[tex]P = $40,000/(1 + 0.06/2)^{(2*18)}\\P = $40,000/(1.03)^{36}[/tex]

P = $40,000/2.4271
