The side lengths x and y are √( 50² - y²) and √50² - x² respectively.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

In a right angle triangle, the length of one side can be determined using the Pythagorean theorem:

x² + y² = hypotenuse²

In the given triangle the length of hypotenuse is 50 cm

x² = 50² - y²

x=√( 50² - y²)

y = √50² - x²

Hence, the side lengths x and y are √( 50² - y²) and √50² - x² respectively.

Answer:

[tex]y=4(x-7)^2-196[/tex]

Step-by-step explanation:

Given quadratic equation:

[tex]y=4x^2-56x[/tex]

Factor out the coefficient of the term x²:

[tex]y=4(x^2-14x)[/tex]

Add and subtract the square of half the coefficient of the term in x inside the brackets:

[tex]y=4\left(x^2-14x+\left(-\dfrac{14}{2}\right)^2-\left(-\dfrac{14}{2}\right)^2\right)[/tex]

Simplify:

[tex]y=4\left(x^2-14x+\left(-7\right)^2-\left(-7\right)^2\right)[/tex]

[tex]y=4\left(x^2-14x+49-49\right)[/tex]

Factor the perfect square trinomial created by the first three terms inside the brackets:

[tex]y=4\left((x-7)^2-49\right)[/tex]

Distribute:

[tex]y=4(x-7)^2-196[/tex]

The equation is now in vertex form y = a(x - h)² + k, where (h, k) is the vertex of the parabola (turning point).

Compare the equation with the vertex formula to identify the values of h and k:

Therefore, the coordinates of the turning point (vertex) are (7, -196).

The experimental probability of getting an odd number on the next toss is 51.3%.

Probability is a measure of the likelihood of an event occurring. In the case of the six-sided number cube, the theoretical probability of getting an odd number on any one roll is 3 out of 6, or 1/2, or 50%. However, this is a theoretical value and may not match the actual results obtained from a set of experiments.

The experimental probability of an event is calculated by observing the actual results of a series of trials and comparing it to the number of possible outcomes. In this case, the number cube was tossed 150 times and the results were recorded in the table. The frequency of the odd numbers (1, 3, and 5) was found to be 77.

The experimental probability of getting an odd number on the next toss can be calculated by dividing the frequency of the odd numbers by the total number of tosses, which is 150. 77/150 = 0.513 or 51.3%.

Therefore, the experimental probability of getting an odd number on the next toss of the six-sided number cube is 51.3%.

The answers for the asked probabilities are a) 1/6, b) 5/36, c) 1/36 and d) A and B events are not independent.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given that, Antonia rolls a pair of fair six-sided dice. A is the event that the first die lands on 5 and B is the event that the sum of the two dice is 6.

Probability = possible outcomes / favorable outcomes

Suppose that Antonia rolls a pair of fair six-sided dice.

All possible outcomes are:

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

(36 outcomes in total)

a) A = the first die lands on 5

Favorable outcomes:

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6 outcomes)

Therefore, the probability that the first die lands on 5 = P(A) = 6/36 = 1/6

b) B = the sum of the two dice is 6

Favorable outcomes:

(1, 5), (2, 4), (3, 3), (4, 2), (5, 1) = (5 outcomes)

Therefore, the probability that the sum of the two dice is P(B) = 6 = 5/36

c) A∩B = the first die lands on 5 and the two dice add up to 6

Favorable outcomes:

(5, 1) = 1 outcome

Therefore, the probability that the first die lands on 5 and the two dice add up to6 = P(A∩B) = 1/36

d) Two events are independent when;

P(A∩B) = P(A) · P(B)

Since,

1/36 ≠ 5/36 · 1/36

Therefore, A and B events are not independent.

Hence, the answers for the asked probabilities are a) 1/6, b) 5/36, c) 1/36 and d) A and B events are not independent.

With the value tanθ = 4/3 on the interval (π, 3π/2), using trigonometric identities sin 2θ = 24/25 , cos 2θ = -7/25 , tan 2θ = -8/7.

First, we'll find sin 2θ:

sin 2θ = 2sinθcosθ

We can use the identity tanθ = sinθ/cosθ to find sinθ and cosθ:

sinθ = 4/5 and cosθ = 3/5

So,

sin 2θ = 2(4/5)(3/5) = 24/25

Next, we'll find cos 2θ:

cos 2θ = cos^2θ - sin^2θ = 1 - 2sin^2θ

Using the values of sinθ and cosθ that we found earlier:

cos 2θ = 1 - 2(4/5)^2 = 1 - 32/25 = -7/25

Finally, we'll find tan 2θ:

tan 2θ = (2tanθ)/(1 - tan^2θ)

Using the value of tanθ that we were given:

tan 2θ = (2(4/3))/(1 - (4/3)^2) = (8/3)/(-7/9) = -8/7

So, the values of sin 2θ, cos 2θ, and tan 2θ are:

sin 2θ = 24/25

cos 2θ = -7/25

a. The total of the two sides of the right triangle using Algebraic expression is 3x²+7x-4.

b. The length of the missing side of the triangle is 3x³-4x²-15x+5.

c. If the value of x=2, then the length of the three sides of the triangle is

   a=11, b=11 and c= -17.

d. No, it is not possible to have these side lengths for a right triangle.

Algebra is a discipline of mathematics that studies symbols and the mathematical operations that can be applied to them. These symbols are referred to as variables because they don't have predetermined values. These values are usually represented in algebra by variables, which are symbols like x, y, z, p, or q. These symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations in order to ascertain the values.

a. Let the sides of the right triangle be a, b and c.

Given, one side of the triangle is 2x² + 2x - 1 and

another side is 5x + x² -3.

So, let a = 2x²+2x-1 and b = 5x+x²-3

Now, the total of the two sides= a+b

          a+b

         =2x²+2x-1 + 5x+x²-3

         = 3x²+7x-4

Therefore, the total of the two sides of the right triangle = 3x²+7x-4.

b. Now the perimeter of the triangle is given= 3x³-x²-8x+1.

Given, a+b+c=3x³-x²-8x+1.

We already have a+b, so by simplifying the equation a+b+c=3x³-x²-8x+1

we can find the length of the third side, c.

a+b+c= 3x³-x²-8x+1

⇒3x²+7x-4 +c= 3x³-x²-8x+1

⇒c= 3x³-x²-3x²-8x-7x+1+4

⇒c= 3x³-4x²-15x+5.

Therefore, length of the missing side is 3x³-4x²-15x+5.

c. We have the three sides of the triangle with us which are:

a = 2x²+2x-1

b = 5x+x²-3

c = 3x³-4x²-15x+5

Now putting the value of x as 2 in the equations as follows:

a= 2(2²) +2(2)-1

 = 8+4-1

 =11

b=5(2) +2²-3

 = 10+4-3

 =11

c=3(2³)- 4(2²) -15(2) +5

 =24-16-30+5

 = -17

Therefore, the length of the three sides of the right triangle

are 11, 11 and -17.

d. The sides of the right triangle are.

a = 11

b = 11

c = -17

We know as per the Pythagorean theorem c² = a² + b².

Accordingly, c²= 289 & a² = 121 and b²= 121, a² + b²= 242

which shows that c² is not equal to a² + b².

As, the sides of the triangle does not follow the Pythagorean theorem, so these are not the sides of a right-angle triangle.

A parabola is a plane curve created when a point moves in such a way that the distance it travels from a fixed point to a fixed line.

According to the given problem,

y = (x - 5)(50 - 2x)

⇒ y + (-(x - 5)(50 - 2x) = (x - 5)(50 - 2x) + (-(x - 5)(50 - 2x)

⇒ y - (x - 5)(50 - 2x) = (x - 5)(50 - 2x) - (x - 5)(50 - 2x)

⇒ y - (x - 5)(-2x + 50) = 0

⇒ y - (-x *2x + x*50 + 5*2x -5*50) = 0

⇒ y - ( -2x² + 50x + 10x - 250) = 0

⇒ y - ( - 2x² + 60x - 250 ) = 0

⇒ y + 2x² - 60x + 250 = 0

⇒ 2x² -60x + y + 250 = 0

⇒ ( 2x² - 60x ) + y + 250 = 0

⇒ 2 ( x² - x) + y + 250 = 0

⇒ 2 ( x² - x) + y + 250 = 0

⇒ 2 ( x² - 30x ) + y + 250 = 0

⇒ 2( x² + 2(-15)x + 225 -225 +y + 250 = 0

⇒ 2( x - 15 )² + 2(-225) + y + 250 = 0

⇒ 2( x - 15 )² + y = -2(-225) - 250

⇒ 2( x - 15 )² + y = 450 - 250

⇒ 2( x - 15 )² + y = 200

⇒ y = -2( x - 15 )² + 200

This equation is in the form of y =  a(x - h)² + k where the vertex of the parabola is (h , k).

Therefore the vertex of the parabola is at (15 , 200)

Hence, we can conclude that Sofie will maximum profit of $200 if she sells a scarf at 15$ and will make the least profit if she sells the scarf at $5 or less.

Taxes are a mandatory contribution to the state. So sales must pay taxes, and it is stated that the rate of tax that must be paid is 5.5%

The way to calculate tax from sales is to multiply the tax rate by the income from sales.

the income = $58

the rate of tax = 5.5%

the tax to be paid by sales = the income x the tax

                                             = $58 x 5.5%

Answer:

a. To find the annual net income, subtract the annual expenses from the annual rental income.

The annual rental income = $750 * 12 months = $9,000

So, the annual net income = $9,000 - $6,890 = $2,110

b. To find the annual yield, divide the annual net income by the investment cost (the down payment) and multiply by 100 to get the answer as a percentage.

The annual yield = ($2,110 / $28,500) * 100 = 7.41%

c. To find the monthly rent required to get a yield of 90%, divide the investment cost by the desired yield and divide by 12 to get the monthly rent.

The investment cost = $28,500

The desired yield = 0.90

So, the monthly rent = ($28,500 / 0.90) / 12 = $2,306.25

The measures of the angles X, Y, and Z are 5, 50, and 125 degrees.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given that in ∆XYZ, the measures of angles X, Y, and Z, respectively, are in the ratio 1:10:25.

We have to find the measure of each angle.

Let the measures can be expressed as 1x, 10x, and 25x, respectively, where x is an arbitrary value.

We know that the sum of the angles of a triangle is always 180 degrees, so:

1x + 10x + 25x = 180

36x = 180

Divide both sides by 36

x = 5

It is important to use a device like a random number table in a simulation because Option A Chance plays a part in the process being simulated.

In simulations, a random number table is used to incorporate the element of chance into the process being modeled. The reason this is important is that many real-world processes involve uncertainty and randomness, and to accurately simulate these processes, it is necessary to include these elements.

For example, in simulating the stock market, stock prices can be modeled as random variables, because they are influenced by a variety of unpredictable factors such as changes in interest rates, company earnings, geopolitical events, and investor sentiment. To simulate this process, a random number table can be used to generate random numbers that represent these unpredictable factors.

By using a random number table, the simulation can model the uncertainty and randomness inherent in the real-world process, which makes the simulation more accurate and realistic. This is why it is important to use a device like a random number table in a simulation when chance plays a part in the process being simulated.
