The quadrilateral you're describing is a Kite. A kite is a quadrilateral with two pairs of consecutive congruent sides, and its diagonals meet at a right angle.

Step 1: Pick any two points

The points are represented as (x1,y1), (x2,y2).

where x1= -4, y1= -8, x2= 0, y2= 4

Step 2: Write out the formula of the equation to use

Step 3: Substituting the values and to get the equation

The equation that represents the graph is y= 3x+4.

Option A is the correct answer.

Answer:

\(\displaystyle a = \frac{8}{5}\).

Step-by-step explanation:

Two vectors \((x_1,\, y_1)\) and \((x_2,\, y_2)\) are parallel to one another if and only if the ratio between their corresponding components are equal:

\(\displaystyle \frac{x_1}{x_2} = \frac{y_1}{y_2}\).

Equivalently:

\(\displaystyle \frac{x_1}{y_1} = \frac{x_2}{y_2}\).

For the two vectors in this equation to be parallel to one another:

\(\displaystyle \frac{a}{4} = \frac{2}{5}\).

Solve for \(a\):

\(\displaystyle a = \frac{8}{5}\).

\(\displaystyle \frac{8}{5}\) would be the only valid value of \(a\); no other value would satisfy the \(\displaystyle \frac{x_1}{y_1} = \frac{x_2}{y_2}\) equation.

The cheapest price Sam would pay for 10kg of cake for the party is $5000 from Mega Mart.

To find the cheapest price Sam would pay for 10kg of cake for the party, we need to compare the prices of the available cakes and determine the most cost-effective option.

At Mega Mart, a 5kg cake costs $2500.

Therefore, the price per kilogram for this cake is:

Price per kilogram at Mega Mart = $2500 / 5kg = $500/kg.

At the same time, a 2kg chocolate cake costs $1200.

So, the price per kilogram for this cake is:

Price per kilogram for the chocolate cake = $1200 / 2kg = $600/kg.

Now, let's calculate the total price for 10kg of cake from each option:

Total price at Mega Mart for 10kg = $500/kg \(\times\) 10kg = $5000.

Total price for 10kg of chocolate cake = $600/kg \(\times\) 10kg = $6000.

Comparing the two options, we see that the Mega Mart cake is the more cost-effective choice.

Sam would pay a total of $5000 for 10kg of cake from Mega Mart, whereas the chocolate cake would cost $6000 for the same quantity.

Therefore, the cheapest price Sam would pay for 10kg of cake for the party is $5000 from Mega Mart.

In summary, Sam would pay the cheapest price of $5000 to purchase 10kg of cake for the party from Mega Mart.

Explanation:

Let's solve the second equation for y to get it into slope intercept form.

\(-3x + \frac{1}{2}y = -3\\\\\frac{1}{2}y = 3x-3\\\\y = 2(3x-3)\\\\y = 6x-6\\\\\)

Compare this to \(y = 6x-b\) and we see that b = 6

Therefore, if b = 6, then the first equation will be exactly identical to the second original equation. The two equations would produce infinitely many solutions.

All of the infinitely many solutions would be of the form (x,y) = (x, 6x-6) where x is any real number.

The domain of the composite function f(g(x)) is equal to (x - 2)/(4 + 4x).

A function is composite when the co- domain of the first mapping is the domain of the second mapping

We shall evaluate the domain of the function f(g(x)) as follows:

f(g(x)) = 1 ÷ 12/[(x - 2) + 4]

f(g(x)) = 1 ÷ [12 + 4(x - 2)]/(x - 2) {simplify the denominator to a single fraction}

f(g(x)) = 1 ÷ (12 + 4x - 8)/(x - 2) {open bracket for 4(x - 2)}

f(g(x)) = 1 ÷ (4 + 4x)/(x - 2) {simply like terms}

f(g(x)) = 1 × (x - 2)/(4 + 4x) {changing division to multiplication}

f(g(x)) = (x - 2)/(4 + 4x)

Therefore, the result (x - 2)/(4 + 4x) is the domain of the composite function f(g(x)).

Answer:

x = 3/2 or x = -1

Step-by-step explanation:

2x² - x - 3 = 0

2*(-3) = -6

Factors of -6:

(-1, 6), (1, -6), (-2, 3), (2, -3)

We need to find a pair that adds up to the co-eff of x which is (-1)

Factors :(2,-3)

2 - 3 = -1

so, 2x² - x - 3 = 0 can be written as:

2x² + 2x - 3x - 3 = 0

⇒ 2x(x + 1) -3(x + 1) = 0

⇒ (2x - 3)(x + 1) = 0

⇒ 2x - 3 = 0 or

x + 1 = 0

⇒ 2x = 3 or x = -1

⇒ x = 3/2 or x = -1

The probability that it weighs more than 51 pounds exactly 53 pounds.

Given that, mean weight of 50 pounds and a standard deviation of 0.5 pounds.

We need to find the probability that it weighs more than 51 pounds,

P(X = 53) = 0

z = (51 - 50) / 0.5 = 2.00

P(X > 51) = P(z > 2.00) = 0.0228

z1 = (49 - 50) / 0.5 = -2.00

z2 = (51 - 50) / 0.5 = 2.00

P(49 < X < 51) = P(-2.00 < z < 2.00) = P(z < 2.00) - P(z < -2.00) = 0.9772 - 0.0228 = 0.9544

Hence, the probability that it weighs more than 51 pounds exactly 53 pounds.

The value of length BC is 18.9

Cosine Rule states that the square of the length of any side of a given triangle is equal to the sum of the squares of the length of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.

Therefore,

c² = a² + b² - 2abcosC

To find the length BC we use cosine rule.

c² = 13² + 7² - 2(13)(7)cos140

c² = 218 - 182cos140

c² = 218-(-139.42)

c² = 218+139.2

c² = 357.2

c = √357.2

c = 18.9

The distance between the fire and station B is 10.7miles

The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.

The angle at A = 90- 35

= 55°

The angle at B = 90-49

= 41°

Angle at the fire = 180-(41+55)

= 180-96 = 84°

Using sine rule

sin84/13 = sin55/x

xsin84 = 13sin55

0.995x = 10.65

x = 10.65/0.995

x = 10.7 miles

Interpretation: On average, we lose about 95 cents each time we play the game.

This is not a fair game because the expected value is not 0.

=============================================================

Explanation:

There is only one way to win the game which is to match all the numbers.

This is out of 376,740 different ways to select 6 items from a pool of 28. The steps on how to get this value are shown below

\(_n C _r = \frac{n!}{r!*(n-r)!}\\\\_{28} C _{6} = \frac{28!}{6!*(28-6)!}\\\\_{28} C _{6} = \frac{28!}{6!*22!}\\\\_{28} C _{6} = \frac{28*27*26*25*24*23*22!}{6!*22!}\\\\_{28} C _{6} = \frac{28*27*26*25*24*23}{6!}\\\\_{28} C _{6} = \frac{28*27*26*25*24*23}{6*5*4*3*2*1}\\\\_{28} C _{6} = \frac{271,252,800}{720}\\\\_{28} C _{6} = 376,740\\\\\)

I used the nCr combination formula. n = 28 is the pool size and r = 6 is the sample size.

Therefore, the probability of winning is 1/376740 and the probability of losing is 1-1/(376740) = 376739/376740

Multiply the odds found by each corresponding net winnings

Win: (1/376740)*(20,000) = 0.05308700960874

Lose: (376739/376740)*(-1) = -0.99999734564951

Then add up those results

0.05308700960874 + (-0.99999734564951) = -0.94691033604078

Rounding to the nearest cent, we get -0.95

The expected value is -0.95

We expect to lose, on average, 95 cents every time we play the game. The game is considered not fair because the expected value is not 0. The game is in favor of the lotto company.

The probability of getting a sum of 5 will be 4 /36. The correct option is B.

Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favorable outcomes to all outcomes.

Probability = Number of favorable outcomes / Number of samples

Given that the die is rolled twice has six sides. The probability of getting a sum of 5 will be calculated as:-

Number of favourable outcomes = { 1,4 } { 4,1 } { 2,3}{3,2} = 4

Total outcomes = 36

Probability = Number of favorable outcomes / Number of samples

Probability = 4  /36

The required value of c is 16 which is the correct answer that would be an option (C).

In triangle LMN, m∠L = (4c + 47). If the exterior angle to L measures 69°,

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two interior angles that are not adjacent to it.

In the case of triangle LMN, we can use the given information to write the following equation:

⇒ 180 - 69 =  (4c + 47)

⇒ 111 = 4c + 47

⇒ 4c = 111- 47

⇒ 4c = 64

⇒ c = 64/4

Apply the division operation, and we get

⇒ c = 16
