Convert the equation to the standard form for a hyperbola 4x^2-25y^2-8x+50y-121=0
Answers
4x²-25y²-8x+50y-121=0
Group terms that contain the same variable, and move the constant to the opposite side of the equation
(4x²-8x)+(-25y²+50y)=121
Factor the leading coefficient of each expression
4(x²-2x)-25(y²-2y)=121
Complete the square twice. Remember to balance the equation by adding the same constants to each side.
4(x²-2x+1)²-25(y²-2y+1)²=121+4-25
Rewrite as perfect squares
4(x-1)²-25(y-1)²=100
Divide both sides by the constant term to place the equation in standard form
(4/100)(x-1)²-(25/100)(y-1)²=100/100
(1/25)(x-1)²-(1/4)(y-1)²=1
[(x-1)²]/25-[(y-1)²]/4=1
the answer is
[(x-1)²]/25-[(y-1)²]/4=1

A nontoxic furniture polish can be made by combining vinegar and olive oil. the amount of oil should be five times the amount of vinegar. how much of each ingredient is needed in order to make 39 oz of furniture polish?
Answers
Let V be the amount of vinegar and L be the amount of oil.
Since the amount of oil is 5 times the amount of vinegar, L = 5V. We know that together they form 39 oz; therefore
V + 5V = 39
6V = 39
Divide both sides by 6:
6V/6 = 39/6
V = 6.5
L = 5V = 5(6.5) = 32.5
Final answer:
To make 39 oz of non-toxic furniture polish with the ratio of olive oil being five times the amount of vinegar, 6.5 oz of vinegar and 32.5 oz of olive oil are needed.
Explanation:
We know the oil to vinegar ratio is 5:1.
Let x be the amount of vinegar: We can use any variable to represent the unknown amount.
Set up the equation: Since the total volume is 39 oz and the ratio is 5:1, we have the equation: x (vinegar) + 5x (olive oil) = 39 oz.
Combine like terms: 6x = 39 oz.
Solve for x (vinegar): x = 39 oz / 6 = 6.50 oz.
Calculate the olive oil amount: Olive oil = 5 × vinegar = 5 × 6.50 oz = 32.50 oz.
Therefore, you'll need 6.50 oz of vinegar and 32.50 oz of olive oil to make 39 oz of furniture polish.
Remember to always test the polish on a small inconspicuous area of the furniture before applying it to the entire surface. And, for best results, use a clean, soft cloth to apply the polish and buff it to a shine.

Now the area of the circular fountain:
Area of the Circular Fountain = [tex] \pi r^2[/tex]
Since, r=6x
Therefore,
Area of the Circular Fountain = [tex] \pi (6x)^2 = 36 \pi x^2[/tex]
Now the final Area of the yard would be:
Final area of the Yard = Total Area of the Yard - Area of the Circular Fountain
Final area of the Yard = [tex]266x^2[/tex] - [tex]36 \pi x^2[/tex]
=> Final area of the Yard = [tex]2x^2(133 - 18 \pi)[/tex] (Option D)

Now the area of the stadium:
Area of the stadium = 1x * 4x = [tex]4x^2[/tex]
Now the final Area of the lot would be:
Final area of the lot= Total Area of the lot - Area of the stadium
Final area of the lot= [tex]60x^2[/tex] - [tex]4x^2[/tex]
=> Final area of the lot = [tex]56x^2[/tex] (Option A)

The chance of each given event happening is 1/6 because there are 6 different number on the dice and only 1 number is chose.
Therefore to find the combined probability, we have to multiply all the individual probabilities.

Or
(1/6)^3
The answer is about 0.46%,
Probability of getting first die rolled is a 1, second die rolled is a 2 and third die rolled is a 3 is equals to 0.46% (nearest tenth).
What is probability?
" Probability is a mathematical expression which represents the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Possible outcomes on each die = { 1, 2, 3, 4, 5, 6}
Substitute the value in the formula as per the given condition we get,
Probability that the first die rolled is a 1 = ( 1 / 6)
Probability that the second die rolled is a 2 = ( 1 / 6)
Probability that the third die rolled is a 3 = ( 1 / 6)
Required Probability = (1 / 6) × (1 / 6) ×(1 / 6)
= ( 1 / 216)
= 0.0046
= 0.46% (nearest tenth)
Hence, required probability (nearest tenth) = 0.46%

We want to find (f-g) (x), we can simply obtain the result by subtracting g (x) from f (x) as follows:
(f-g) (x) = f (x) - g (x)
(f-g) (x) = 3x + 1 - (x²-6)
(f-g) (x) = 3x + 1 - x² + 6

[tex]f(x) = 3x +1[/tex] and[tex]g(x) = x^2-6[/tex]
then , (f - g)(x) = f(x) - g(x)
Substitute, we have,
[tex]f(x) - g(x)=3x+1-(x^2-6)[/tex]
Applying plus - minus rule[tex]-(-a)=a[/tex], we have,
[tex]f(x)-g(x)=3x+1-x^2+6[/tex]

To find the missing side, you have to write a proportion because the sides are proportional.
When an angle is bisected like this, you can write:
28/x = 12/(30 - x)
Cross multiplying will give you:
12x = 840 - 28x
40x = 840
x = 21
You could plug the 21 back in and you will see that the sides are proportional.

y = mx + b Which variable represents the slope?
Answers
The variable 'm' represent the slope.
What is slope?The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.
Given:
y= mx + b
The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line.
The net change in y coordinate is Δy, while the net change in the x coordinate is Δx.
So the change in y coordinate with respect to the change in x coordinate can be written as,
m = Δy/Δx
where, m is the slope
The slope of a line can be calculated from the equation of the line. The general slope of a line formula is given as,
y = mx + b
where,
m is the slope, such that m = tan θ = Δy/Δx
θ is the angle made by the line with the positive x-axis
Δy is the net change in y-axis
Δx is the net change in x-axis

The doubly-shaded area is the solution set. The dashed line is not included.
Answer:
Graph B is the answer.
Step-by-step explanation:
We know that both functions are inequalities, however,
The second one (red on the graph) has 'less or equal sign, ≤' meaning that, the line of the function is included as shown on graph B with a continuous line.
The first one has a 'greater than, >' meaning that the line of the function is not included, therefore the line is a dotted line, as shown on graph B.
The shaded area must be between the two inequalities because that where the X's can be met.
Therefore, the answer is graph B.
a. The figure at the right shows a long rectangular strip of paper, one corner of which has been folded over to meet the opposite edge, thereby creating a 30-degree angle. Given the width of the strip is 12 inches, find the length of the crease.
b. Instead of a 30-degree angle, suppose that the angle has an unspecified size t. Use trigonometry to find the length of the crease, expressed in terms of t.
c. Find the approximate value of t that makes the crease as short as it can be. Restrict your attention to values of t that are less than 45 degrees. Explain your method.

m∠CDF = m∠CAE = 2t
Putting these relationships together, we have
.. DF/CD = cos(2t) = (12-x*sin(t))/(x*sin(t))
Solving for x, we get
.. x*sin(t)*cos(2t) = 12 -x*sin(t)
.. x*sin(t)*(1 +cos(2t)) = 12
.. x = 12/(sin(t)*(1 +cos(2t))
.. x = 6/(sin(t)*cos(t)^2)
For t = 30°, x = 6/(3/8) = 16
For a 30° angle, the length of the crease in 16 inches.
B. From above,
.. crease length = (6 inches)/(sin(t)*cos(t)^2)
C. Using a graphing calculator, we can find the angle that makes the crease length a minimum. See the second figure. It is about 35.264°.
