if there is a vertical line that intersects the graph of a relation in more than one point then the relation is a function true or false
Which equation represents a line that passes through (5, 1) and has a slope of ?
y – 5 = 1/2(x –1)
y – 1/2 = 5(x –1)
y – 1 = 1/2(x –5)
y – 1 = 5|x-1/2|
Answer:
ITS C
y -1 = 1/2 ( x -5)
The equation represents a line that passes through (5, 1) and has a slope of 1/2 is given by (A) y - 5 = 1/2 (x-1).
What is Slope?The tangent value of the angle formed between a straight line and positive x-axis is called the Slope of that straight line.
If the slope of a line is m and the line is satisfied by point (a,b) then the equation of the line is given by,
y - b = m (x - a)
Here in the problem it is given that the slope is 1/2 and line passes thorugh (5,1).
So, a = 5, b = 1, m = 1/2
Hence the equation of the straight line is given by,
y - 5 = 1/2 (x - 1)
Hence the correct option is (A)

Classify the following triangle.Check all that apply.
Answer:
Obtuse and Isosceles
:) Apex
The triangle in the image can be classified as follows:
The correct options will be
Right [ F] : One of the angles is 90 degrees.
Isosceles [ D]: Two of the sides are equal (the two shorter sides).
We can see from the triangle that two of the angles measure 41 degrees each and the third angle is 98 degrees. The sum of the angles in a triangle is 180 degrees, and since 41 + 41 + 98 = 180, we know that the triangle is valid.
Right triangles can also be isosceles (in fact, there is a specific type of right triangle called a 45-45-90 triangle). So, this triangle qualifies for both classifications.
The triangle cannot be classified as:
Acute [ B]: Acute triangles have all angles less than 90 degrees.
Obtuse [ A]: Obtuse triangles have one angle greater than 90 degrees.
Equilateral [ E]: Equilateral triangles have all three sides equal.
The complete question is: Classify the following triangle.Check all that apply.

am-n=p (solve for a)
The value of a = (p + n) / m.
To isolate a in the given equation am - n = p, follow these steps:
Start with the original equation: am - n = p.
Add n to both sides of the equation to eliminate n from the left-hand side:
am - n + n = p + n
am = p + n.
Next, divide both sides of the equation by m to solve for a:
(am) / m = (p + n) / m
a = (p + n) / m
Therefore, a = (p + n) / m is the solution to the equation.
Trevor is swimming laps to raise money for the local food bank. He earns $1.85 per lap and has already swum 23 laps.
• Write an inequality to show how many more laps Trevor needs to swim in order to raise more than $100.
Answer: L greater than 31
Step-by-step explanation:
Trevor is swimming laps to raise at over 100 dollars for the local food bank. He earns $1.85 per lap and has already swum 23 laps.
This means that the total amount that he has raised is number of laps that he has swum × the amount he earns per lap. Therefore,
Amount that he has already raised
= 1.85 × 23 = $42.55
100 - 42.55 = 57.45
He still needs to raise an amount greater than $57.45
To raise this amount, he needs to swim more laps. Number of laps that he needs to swim will be
57.45/1.85 = 31.05
Approximately 31 laps
Let the number of laps that he needs to swim be L
The inequality to show how many more laps Trevor needs to swim in order to raise more than $100 will be
L greater than 31
factor x^2 + 3x + 2
infinity/infinity
To factor the quadratic x^2 + 3x + 2, it can be written as (x + 1)(x + 2). The concept of infinity over infinity (∞/∞) is an indeterminate form in limits and usually requires further techniques to evaluate.
To factor x^2 + 3x + 2, you want to find two numbers that both add up to +3 (the coefficient of x) and multiply to +2 (the constant term). These numbers are +1 and +2. Thus, you can express the quadratic equation as a product of two binomials:
x^2 + 3x + 2 = (x + 1)(x + 2).
As for the concept of limits like ∞/∞, it commonly arises when evaluating the behavior of functions as the variable approaches infinity. It represents an indeterminate form which requires further algebraic manipulation or techniques such as L'Hôpital's rule to find a meaningful limit.

What values of c and d make the equation true?
c = 2, d = 2
c = 2, d = 4
c = 6, d = 2
c = 6, d = 4
Answer:
c=6 and d=2 makes the equation true
Step-by-step explanation:
[tex]\sqrt[3]{162x^cy^5} = 3x^2y(\sqrt[3]{6y^d})[/tex]
plug in c=2 and check
[tex]\sqrt[3]{162x^2y^5}[/tex]
We cannot simplify cuberoot (x^2)
So c=2 does not works
Lets try with c=6 and d=2
[tex]\sqrt[3]{162x^6y^5}[/tex]
Cuberoot(x^6) = x^2
cuberoot (y^5)= ycuberoot (y^2)
[tex]\sqrt[3]{162x^6y^5} = 3x^2y(\sqrt[3]{6y^2})[/tex]
So c=6 and d=2 makes the equation true

In isosceles triangle the length of the base is twice shorter than the length of a leg. The perimeter of this triangle is 50cm. Find the lengths of all sides.
To solve this question, we have to:
Understand the concept of an isosceles triangle.Use this concept, along with the perimeter concept, to build the equation to find the length of the sides.Doing this, we get that the length of the base is 10 cm and the length of the legs is 20 cm.
Isosceles triangle:
In an isosceles triangle, two sides have the same measure. An example is given by the picture at the end of this answer.
Perimeter:
The perimeter of a polygon, in this case a triangle, is the sum of all it's sides.
In this question:
Perimeter of 50 cm;Two legs of l;Base is half the leg, so l/2.Then, the equation is:
[tex]l + l + \frac{l}{2} = 50[/tex]
[tex]2l + \frac{l}{2} = 50[/tex]
[tex]\frac{4l + l}{2} = 50[/tex]
[tex]5l = 100[/tex]
[tex]l = \frac{100}{5}[/tex]
[tex]l = 20[/tex]
Thus:
The length of the legs is of 20 cm.The length of the base is of 20/2 = 10 cm.A similar question is found at https://brainly.com/question/20321307
Find p(x = 4) if x has a poisson distribution such that 3p(x = 1) = p(x = 2).
The formula for Poisson distribution is:
P (x) = e^-k * k^x / x!
We know that:
3P(x = 1) = P(x = 2)
Therefore:
3 [e^-k * k^1 / 1!] = e^-k * k^2 / 2!
Simplifying by cancelling similar terms:
3 / 1! = k / 2!
k = 3 * 2! / 1!
k = 6
So at x = 4:
P (x = 4) = e^-6 * 6^4 / 4!
P (x = 4) = 0.1339 or 13.39%

The average yearly snowfall in chillyville is normally distributed with a mean of 55 inches. if the snowfall in chillyville exceeds 60 inches in 15% of the years, what is the standard deviation?
The standard deviation of the snowfall in Chillyville, when the snowfall exceeds 60 inches in 15 percent of the years, is 5 inches.
Explanation:The question is about finding the standard deviation of the normally distributed data for snowfall in Chillyville. From the given problem, we have the mean (μ) as 55 inches and the given probability for snowfall exceeding 60 inches is 15% or 0.15 which happens to correspond to 1 - 0.85 = 0.15 in the standard normal distribution. This places it in the 85th percentile of the standard normal distribution, which corresponds to a Z-score of about 1.
From the Z-score formula Z = (X - μ)/σ, where X is the data point, μ is the mean and σ is the standard deviation, we can substitute the known values: 1 = (60 - 55)/σ . Solving it gives σ = 60 - 55, which implies the standard deviation is 5 inches.
