A) 4 square yards
B) 3 square yards
C) 2 square yards
D) 1 square yards

answer: Kevin received $30,000, and Bob received $70,000.

According to the problem, Bob received $10,000 more than two times what Kevin received. So, Bob received:

2X + $10,000

We also know that the total amount won is $100,000. Therefore, we can write the equation:

X + (2X + $10,000) = $100,000

Simplifying the equation, we get:

3X + $10,000 = $100,000

3X = $90,000

X = $30,000

Therefore, Kevin received $30,000, and Bob received:

2X + $10,000 = 2($30,000) + $10,000 = $70,000

So Bob received $70,000.

The equations of the asymptotes of the graph are x = 1, x = -1 and y = 3x

The equation of the function is given as

f(x)=3x^3-24/x^2-1

Set the denominator to 0

So, we have

x^2 - 1 = 0

Apply the difference of two squares

(x - 1)(x + 1) = 0

Evaluate

x = 1 and x = -1 ---- the vertical asymptotes

Here, we have the degree of the numerator to be greater than that of the denominator

So, we have

Step-by-step explanation:

The probabilities are given as follows:

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.

For a probability tree, the sum of the nodes at each level must be of 1.

Then the value of a is obtained as follows:

0.6 + a = 1

a = 1 - 0.6

a = 0.4.

The value of b is obtained as follows:

0.9 + b = 1

b = 0.1.

The values of c and d are free, as long as the sum of these two values is of 1, hence we can attribute:

Answer:

Step-by-step explanation:

Let the total number of beads in the box be x.

Then, the number of red beads in the box is 20% of x = 0.2x.

After increasing the number of red beads by 5%, the number of red beads becomes 1.05 times the original number of red beads, which is 1.05(0.2x) = 0.21x.

The total number of orange and white beads is (100% - 20%) = 80% of x, which is 0.8x.

After increasing the number of orange and white beads by half, the total number becomes 1.5 times the original number, which is 1.5(0.8x) = 1.2x.

So, we have the equation: 0.21x = 0.2x + 123 - 1.2x

Simplifying this equation, we get:

0.01x = 123

x = 12,300

Therefore, the box originally contained 12,300 beads.

The time until the minimum price is reached is 5 months. After this time, the price will start to increase again.

Price is the amount of money that must be paid to acquire a product or service, usually expressed in currency units such as dollars or euros.

The price of the computer system is given by the formula:

P = 170t² - 1700t + 6400

To find the time until the minimum price is reached, we need to find the value of t that corresponds to the vertex of the parabola described by this formula. The vertex is the point at which the price reaches its minimum value.

The formula for the x-coordinate of the vertex of a parabola in standard form (ax² + bx + c) is:

x = -b/2a

In this case, the formula for the price of the computer system is:

P = 170t² - 1700t + 6400

So we can see that a = 170, b = -1700, and c = 6400. Substituting these values into the formula for the x-coordinate of the vertex, we get:

t = -b/2a = -(-1700)/(2×170) = 5

Answer:

the flare will be in the air for approximately 29.09 seconds before fizzling out at a height of 10 meters above ground.

Step-by-step explanation:

To find out how long the flare will be in the air, we need to find the time it takes for the flare to reach a height of 10 meters.

Setting h(t) to 10 and solving for t:

-0.5t² +16t+22 = 10

-0.5t² +16t+12 = 0

Using the quadratic formula:

t = (-b ± √(b² - 4ac)) / 2a

Where a = -0.5, b = 16, and c = 12:

t = (-16 ± √(16² - 4(-0.5)(12))) / 2(-0.5)

t = (-16 ± √(256 + 24)) / -1

t = (-16 ± √280) / -1

t ≈ -1.09 or t ≈ 29.09

Since time cannot be negative, we can ignore the negative root. Therefore, the flare will be in the air for approximately 29.09 seconds before fizzling out at a height of 10 meters above ground.

As stated in the problem description, matrix A transforms the input vector (x, y, and z) into the output vector (y+z, 2x-z, 0).

The matrix A is: | 0 1 1 |, | 2 0 -1 |, | 0 0 0 |

A matrix, sometimes known as matrices, is a rectangular array or table of letters, numbers, or other symbols organized in rows and columns that are used to represent a mathematical object or a characteristic of one.

In linear algebra, matrices describe linear mappings and enable explicit computations. As a result, a significant portion of linear algebra involves the study of matrices, and the majority of the characteristics and operations of abstract linear algebra may be described in terms of matrices. The composition of linear maps, for instance, is represented by matrix multiplication.

Not every matrix has a connection to linear algebra. This is especially true for incidence matrices and adjacency matrices in graph theory.

The matrix A is:

| 0 1 1 |

| 2 0 -1 |

| 0 0 0 |

Applying the matrix multiplication A x y z to any random vector (x, y, z)   will demonstrate why:

| 0 1 1 | | x | | y + z |

| 2 0 -1 | x | y | = | 2x - z |

| 0 0 0 | | z | | 0 |

Hence, as stated in the problem statement, matrix A transforms the input vector (x, y, and z) into the output vector (y+z, 2x-z, 0).

The equation of the line that is perpendicular to y = 2x + 4 and goes through the point (6, 4) is y = (-1/2)x + 7.

To find the equation of a line that is perpendicular to y = 2x + 4 and goes through the point (6, 4), we first need to determine the slope of the given line.

The equation y = 2x + 4 is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. Therefore, the slope of the given line is 2.

The slope of a line perpendicular to this one will be the negative reciprocal of 2, which is -1/2.

So the equation we are looking for will have a slope of -1/2 and will pass through the point (6, 4). We can use the point-slope form of the equation of a line to find it:

y - y1 = m(x - x1)

where m is the slope, (x1, y1) is the point, and x1 = 6, y1 = 4:

y - 4 = (-1/2)(x - 6)

Simplifying:

y - 4 = (-1/2)x + 3

y = (-1/2)x + 7

What is linear regression ?

Linear regression is a statistical method that is used to establish the relationship between two variables, usually represented as a straight line. It is used to determine the extent to which one variable is dependent on the other variable, and to make predictions based on this relationship.

Using linear regression, we want to find the equation of the line of best fit in the form y = mx + b, where m is the slope and b is the y-intercept.

First, we need to calculate some sums:

∑x = 28

∑y = 45

∑xy = 224

∑x² = 140

∑y²= 275

Using these sums, we can calculate the slope m:

m = (n∑xy - ∑x∑y) / (n∑x² - (∑x)²)

m = (7(224) - (28)(45)) / (7(140) - (28)^2)

m = 1.19

Now we can use the slope to calculate the y-intercept b:

b = (∑y - m∑x) / n

b = (45 - (1.19)(28)) / 7

b = -0.37

Therefore, the equation of the line of best fit is y = 1.19x - 0.37.

The cost of having a car towed 14 miles is $103.

What is function ?

In mathematics, a function is a relation between a set of inputs (called the domain) and a set of possible outputs (called the range) with the property that each input is related to exactly one output. Functions are often represented by a formula or rule that describes how to compute the output value from the input value.

The towing cost, C, can be expressed as a function of miles towed, x, using the given information as follows:

C(x) = 75 + 2x

where x is the number of miles towed.

To find the cost of towing a car 14 miles, we can substitute x = 14 into the function:

C(14) = 75 + 2(14)
