A right triangle has a hypotenuse of 9 and a leg of 2 to the square root of 6 what is the missing side
The missing side of the right triangle is √57
To find the missing side of the right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two legs is equal to the square of the length of the hypotenuse.
Let's assume the missing side is represented by the variable x.
According to the Pythagorean theorem:
(2√6[tex])^2 + x^2 = 9^2[/tex]
Simplifying, we have:
[tex]4 \times 6 + x^2 = 81\\24 + x^2 = 81\\x^2 = 81 - 24\\x^2 = 57[/tex]
Taking the square root of both sides, we get:
x = √57
Thus, the missing side of the right triangle is √57

The vertical asymptote of the function are x = ±1/2
Given that we need to determine what is value of the vertical asymptote of the function =
(2x + 1) / (4x²-1)
To find the vertical asymptote of the function f(x) = (2x + 1) / (4x² - 1), we need to determine the values of x for which the denominator becomes zero.
This is because division by zero is undefined, and the function may have vertical asymptotes at those points.
The denominator of the function is 4x² - 1.
To find the values of x that make the denominator zero, we can set it equal to zero and solve for x:
4x² - 1 = 0
Adding 1 to both sides:
4x² = 1
Dividing both sides by 4:
x² = 1/4
Taking the square root of both sides:
x = ±√(1/4)
Simplifying further, we get:
x = ±1/2
Therefore, the values of x that make the denominator zero are x = -1/2 and x = 1/2. These are the vertical asymptotes of the function.

NO SPAM OR I WILL REPORT YOU AND BAN YOU IMMEDIATELY
Where the above is given, Area of Δ ACB ≈ 282.62
Why is this so?
The area of a triangle is given as
Area = 1/2 Base x Height
In this case,
Base = AB
Height = CP
Thus, it is correct to state that Area of Δ ACB = 1/2AB * CP.
How is this so?
First we need to find the height and hypotenuse of the triangle.
that is CP and CB.
CB = a/Cos (63)
CB = 26.43227
CP = √(CB²-PB²)
CP = √(26.4322711750232² - 12²)
CP = 23.55133
Area of ΔPCB = (CP x PB)/2
(12 × 23.551326066062)/ 2
= 141.30796
Since ΔPCB = ΔPCA
and ΔACB = ΔPCB + ΔPCA

which quadratic equation has the roots 3 + i and 3 - i
The quadratic equation that has the roots 3 + i and 3 - i is x² - 6x + 10 = 0.
The general form of a quadratic equation is ax² + bx + c = 0, where a, b, and c are constants.
The roots of the quadratic equation are the values of x that make the equation equal to zero.
Therefore, if a quadratic equation has the roots 3 + i and 3 - i, it can be written in the factored form as (x - (3 + i))(x - (3 - i)) = 0. Expanding this product yields x² - (3 + i + 3 - i)x + (3 + i)(3 - i) = 0.

the headlights on a car are set so the light beam drops 2 in. for 26 ft measured horizontally. If the headlights are mounted 24 in. above the ground, how far ahead of the car will they hit the ground?>
Answer:
0.168 ft aprox
Step-by-step explanation:
To solve this problem, we can use similar triangles and proportions. Let's denote the distance ahead of the car where the light beam hits the ground as "x" (in feet).
According to the given information, the light beam drops 2 inches for every 26 feet horizontally. We can set up the following proportion:
2 inches / 26 feet = x inches / x + 26 feet
To solve for x, we can cross-multiply and solve the resulting equation. Let's convert inches to feet to maintain consistent units:
2 inches = 2/12 feet = 1/6 feet
1/6 feet / 26 feet = x feet / x + 26 feet
1/6 * (x + 26) = 26 * x
x/6 + 26/6 = 26x
x + 26 = 156x
156x - x = 26
155x = 26
x = 26 / 155 ≈ 0.168 ft
Therefore, the headlights will hit the ground approximately 0.168 feet (or 2.016 inches) ahead of the car.
A. How many combinations of the 5 white balls and 1 red ball are possible?
The number of combinations of the 5 white balls and 1 red ball are possible is 1.
We are given that;
White balls=5
Red ball=1
Now,
To find the number of combinations of 5 white balls and 1 red ball, we can use the combinations formula12:
[tex]nCr = n! / (r! (n-r)!)[/tex]
where n is the total number of objects, r is the number of objects to be selected, and ! is the factorial operator.
we can plug in these values into the formula:
[tex]6C6 = 6! / (6! (6-6)!) 6C6 = 6! / (6! 0!) 6C6 = 1 / (1 1) 6C6 = 1[/tex]
So, there is only one combination of 5 white balls and 1 red ball. This makes sense because the order of selection does not matter in a combination. No matter how we arrange the balls, we will always have the same group of 5 white balls and 1 red ball.
Therefore, by combinations and permutations the answer will be 1.

Answer:
[tex]\textsf{B)} \quad C=\dfrac{360^{\circ}\:s}{A}[/tex]
Step-by-step explanation:
In a circle, the ratio of an arc length (s) to the circumference (C) is equal to the ratio of the measure of the arc's central angle (A) to 360°.
This is because:
The circumference (C) represents the distance around the entire circle, and so an arc (s) is a fraction of the whole circumference. In a circle, there are 360° in total, and so a central angle (A) is a fraction of 360°.Therefore, this can be expressed as:
[tex]\dfrac{s}{C}=\dfrac{A}{360^{\circ}}[/tex]
Cross multiply:
[tex]360^{\circ} \cdot s=C \cdot A[/tex]
Now, divide both sides by A to isolate C:
[tex]\dfrac{360^{\circ} \cdot s}{A}=C[/tex]
Therefore, the relationship between the circumference (C) of the circle in which the degree measure (A) of a central angle of a circle intercepts an arc length (s) of the arc is:

predict what will happen to the coordinates of a point (x,y) as the point reflects across a line to produce point (x1,y1)
The reflections are described below.
We know that,
There are two types of reflection:
Reflection with respect to X-axis:
The x-coordinates of a point stay constant when it is mirrored across the X-axis. However, the Y-coordinates are changed into their inverse signs.
As a result, the X-axis reflection of the point (x, y) is (x, -y).
Reflection with respect to Y- axis:
The Y-coordinates of a point stay constant when it is mirrored across the Y-axis. However, the X-coordinates are changed into their inverse signs.
As a result, the Y-axis reflection of the point (x, y) is (-x, y).
Now the reflection is as following:
The point (x, y) when reflected across the x-axis becomes (x', y') = (x, -y)
The point (x, y) when reflected across the y-axis becomes (x', y') = (-x, y)
The point (x, y) when reflected across the line y = x becomes (x', y') = (y, x)

Beth and Kelly spent the same total amount of money for dog sitting while on vacation.

Kelly took her dog, Monty, to Pet Palace and was charged $32 per day and a $45.50 cleaning fee. How many days were Beth and Kelly on vacation?
Beth and Kelly were on vacation for 6 days.
Let's assume that Beth and Kelly were on vacation for "x" days.
For Beth:
The cost per day for dog sitting at Rover Sleepover is $24.50.
Beth also paid a fee of $90.50 for food and cleaning.
So the total cost for Beth's dog sitting can be expressed as:
Total cost for Beth = (Cost per day × Number of days) + Cleaning fee
Total cost for Beth = ($24.50 × x) + $90.50
For Kelly:
The cost per day for dog sitting at Pet Palace is $32.
Kelly also paid a fee of $45.50 for cleaning.
So the total cost for Kelly's dog sitting can be expressed as:
Total cost for Kelly = (Cost per day × Number of days) + Cleaning fee
Total cost for Kelly = ($32 × x) + $45.50
Since both Beth and Kelly spent the same total amount of money, we can set up an equation:
($24.50 × x) + $90.50 = ($32 × x) + $45.50
Simplifying the equation, we get:
$24.50x + $90.50 = $32x + $45.50
Moving the variables to one side and constants to the other side:
$32x - $24.50x = $45.50 - $90.50
Combining like terms, we have:
$7.50x = $45
Dividing both sides of the equation by $7.50:
x = $45 / $7.50
x = 6
Therefore, Beth and Kelly were on vacation for 6 days.

Which choice is a solution to this system of equations? -x=y-4 y=4x+9
The solution to the system of equations is x = 5.4 and y = -1.4
How to determine the solution to the system of equations?From the question, we have the following parameters that can be used in our computation:
-x=y-4 y=4x+9
So, we have
-x = y - 4
y = 4x + 9
Rewrite the equation as
x = -y + 4
y = 4x + 9
So, we have
y = 4(-y + 4) + 9
Open the bracket and evaluate
5y = 9 - 16
So, we have
y = -1.4
Recall that
x = -y + 4
So, we have
x = 1.4 + 4
Evaluate
x = 5.4
Hence, the solution is x = 5.4 and y = -1.4

Using a trigonometric relation, we can see that the value of x is 10.39
How to find the value of x?Here we have a right triangle. We can see that we know the measures of the hypotenuse, and the angle opposite to the side x.
Then to get the value of x, we can use the trigonometric relation:
sin(a) = (opposite cathetus)/hypotenuse.
Replacing the values that we know, we will get.
sin(60°) = x/12
solve that for x:
12*sin(60°) = x
10.39 = x
