The slope-intercept equation of the line that includes the points (1, 1) and (2, 8) is y = 7x - 6.
What is the point-slope form?In Mathematics, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.Next, we would determine the linear equation representing the line which passes through the points (1, 1) and (2, 8) by using the point-slope form as follows:
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 1 = (8 - 1)/(2 - 1)(x - 1)
y - 1 = 7(x - 1)
y = 7x - 7 + 1
y = 7x - 6

What are similar triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are identical, their respective sides are equal in number and their corresponding angles are congruent.
Given that, the height of the person is 1.25 meters, the length of the tree's shadow is 24.65 meters, and the distance between the person and the tree is 20.1 meters.
Let the height of the tree be x.
Note that the scenario makes two similar triangles.
Since the ratio of the side lengths of similar triangles is proportional, it follows:
(24.65 - 20.1)/1.25 = 24.65/x
3.64 = 24.65/x
x = 24.65 / 3.64
x = 6.77
Hence, the height of the tree is 6.77 meters.

Create a rational function that has the
given lines as asymptotes.
1. y = 0, x = −3, x = 0, and x = 2
2. y = 3/2, x = -1, and x= 1/2
The rational functions with the given asymptotes are presented as follows:
1. y = 1/(x³ + x² - 6x).
2. y = 1.5x²/(x² + 0.5x - 0.5).
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.
The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.
For item 1, due to the vertical asymptotes, the denominator is given as follows:
x(x + 3)(x - 2) = x(x² + x - 6) = x³ + x² - 6x.
As the horizontal asymptote is of zero, the numerator has a lower degree than the denominator, hence it can be constant, and the function is given as follows:
y = 1/(x³ + x² - 6x).
For item 2, the denominator is given as follows:
(x + 1)(x - 0.5) = x² + 0.5x - 0.5.
Due to the horizontal asymptote of 3/2, the degree of the numerator must be the same as the denomiator, with a coefficient 3/2 that of the denominator, hence the numerator is given as follows:
3x²/2 = 1.5x².
Meaning that the function is:
y = 1.5x²/(x² + 0.5x - 0.5).

Toula calculates the cost of cementing the bottom and sides of a circular pond. When all costs are considered, the job will cost $175.85 per square metre of finished area. if the pond has a radius of 3 feet and a depth of 2 feet, how much will she charge for the job?
Step-by-step explanation:
First, we need to calculate the area of the pond by using the formula for the area of a circle: πr^2, where r is the radius. In this case, the radius is 3 feet.
3^2 = 9
π * 9 = 28.27 square feet
Now, we need to find the volume of the pond to find the finished area by using the formula for the volume of a cylinder: πr^2h, where r is the radius, h is the height/depth.
28.27 * 2 = 56.54 cubic feet
Finally, we need to convert the square feet to square meters and multiply it by the cost per square meter.
56.54 square feet * 0.092903 square meters/square foot = 5.24 square meters
5.24 square meters * $175.85/square meter = $924.99.
So, the cost of cementing the bottom and sides of the circular pond would be $924.99
Macy's starting balance in her checking account was $654.98. She wrote one check in the amount of $321.45 and made a

amount of the deposit.
$119.25
$114.38
$121.56
$116.74
Answer:
$119.25.
Step-by-step explanation:
Let's call the deposit amount "D".
Starting balance: $654.98
Check amount: -$321.45
Deposit: +D
Ending balance: $452.78
So, we can set up an equation:
$654.98 - $321.45 + D = $452.78
Solving for D:
$654.98 - $321.45 + D = $452.78
$333.53 + D = $452.78
D = $119.25
So the deposit amount was $119.25.
suppose that one customer who participated in the study is chosen at random. what is the probability that the customer had a high level of satisfaction and used the company more than five times per month?
The probability of an event is given by the number of favorable outcomes divided by the total number of possible outcomes.
In this case, the favorable outcome is that the customer had a high level of satisfaction and used the company more than five times per month. The total number of possible outcomes is the total number of customers in the study, which is 700.
Therefore, the desired probability can be calculated as:
P(High satisfaction and more than 5 times per month) = 70 / 700
And the answer is P(High satisfaction and more than 5 times per month) = 70 / 700 = 1/10.

Step-by-step explanation:
Given the following probabilities, compute all joint probabilities.
P(A) = .9
P(B | A) = .4
P(AC) = .1
P(B | AC) = .7
The joint probabilities are: P(A and B) = 0.36, P(A and C) = 0.1, P(AC and B) = 0.07.
What do you mean by Probability?Probability is a measure of the likelihood of an event occurring, expressed as a number between 0 and 1. An event with probability 0 cannot occur, and an event with probability 1 is certain to occur. The probability of an event A is usually written as P(A) and is calculated as the number of favorable outcomes divided by the total number of possible outcomes in the sample space. For example, if a fair six-sided die is rolled, the sample space is the set of all possible outcomes (1, 2, 3, 4, 5, 6), and the probability of rolling a 4 is 1/6. Probability is used in many fields to make predictions, draw inferences, and make decisions under uncertainty.
We can use the formula for conditional probability to calculate the joint probabilities:
P(A and B) = P(B | A) * P(A) = .4 * .9 = .36
P(A and C) = P(A) * P(C | A) = .9 * P(C) / P(A) = .9 * .1 / .9 = .1
P(AC and B) = P(B | AC) * P(AC) = .7 * .1 = .07
So, the joint probabilities are:
P(A and B) = .36
P(A and C) = .1

how to develop the shape of the hole in the cone when it intersects with a cylinder
The generatrix of a cylinder is intersected by a plane parallel to its axis to determine the shape of the hole in the cylinder, while the generatrix of a cone is intersected by a plane via its vertex.
We select cutting planes that intersect both surfaces along their generatrixes in order to construct the intersection points of a cone and a cylinder. A cylinder's generatrix is intersected by a plane parallel to its axis, and a cone's generatrix is intersected by a plane via its vertex.
Since the line passing through the cone's vertex is parallel to the axis of the cylinder, the system of planes that intersect both surfaces in their generatrixes is a pencil-shaped arrangement of planes.
The cone and the cylinder are both intersected by every plane of that pencil in two different generatrixes.
In contrast to the vertices of the surfaces, the junction curve has four points that are intersections of these four lines.

If a pair of linear equation in two variable have no solution then the pair of lines are
If a pair of linear equations in two variables have no solution then the pair of lines are inconsistent or parallel lines.
Solutions of a pair of linear equations:
Depending on the number of variables and type of equations there are 3 types of solutions to an equation.
1. Unique Solution (One solution):
When there is only one variable then the linear equation will have a Unique Solution or One solution. In the case of pair of linear equations, the linear equation will have a unique solution when the straight lines are intersected at a single point.
2. No solution:
When the given pair of linear equations is inconsistent equations the linear equation will have no solutions in common or we can say that the given lines are non-intersected lines. Usually, a pair of parallel lines will have no solutions.
3. Infinite Solutions (Many solutions):
When the given lines are overlapped on each other or coincident with each other the given lines will have Infinite Solutions. These intersected lines.
Therefore,
If a pair of linear equations in two variables have no solution then the pair of lines are inconsistent or parallel lines.

One of the questions asks you to measure the expected acceleration given: Expected acceleration = (5/7)gsin(θ) where g=9.8 m/s2.
The expected acceleration of an object is based on the acceleration due to gravity, which is a constant value of 9.8 m/s2. To calculate the expected acceleration, we use the equation: Expected acceleration = (5/7)gsin(θ), where θ is the angle at which the object is moving.
This equation takes into account the angle of the object and uses the acceleration due to gravity to calculate the expected acceleration. In this equation, the acceleration due to gravity is multiplied by a fraction, which is determined by the angle at which the object is moving. Therefore, the higher the angle at which the object is moving, the greater the expected acceleration.
