the vertices of triangle wxy are located at w(-14,20). x(10,4) and y (-2,-4). what is the approximate length of the midsegment parallel to xy?
The approximate length of the midsegment parallel to xy is 6.63
The midsegment of a triangle is a line segment that connects the midpoints of two sides of the triangle and has the same length as each of the two sides.
To find the midpoint of a line segment, we average the x-coordinates and the y-coordinates of its endpoints.
Since the question stated that the midsegment is parallel to xy, we need to find midpoint of xw and yw.
First, let's find the midpoint of side xw:
Midpoint of xw : ((-14+10)/2, (20+4)/2) = (-2, 12)
Midpoint of yw : ((-14-2)/2, (20-4)/2) = (-8, 8 )
The length of a line segment between two points (x1, y1) and (x2, y2) in a two-dimensional coordinate system can be calculated using the distance formula:
d = √((x2 - x1)^2 + (y2 - y1)^2)
Length line of midpoint xw and midpoint yw :
√((-2-(-8))^2 + (12-(8))^2) = √(6^2 + 4^2) = √(36 + 8) = √44
So, the length of the midsegment is parallel to XY, which is approximately equal to √44 = 6.63

The function [tex]f(x)=\sqrt[3]{x+4}[/tex] is transformed to [tex]g(x) = \sqrt[3]{x-1} +3[/tex]
What transformations are performed from function f to function g?
Choose the answers that are correct:
1. Function f is translated up 3 units.
2. Function f is translated to the right 5 units.
3. Function f is translated to the right 3 units.
4. Function f is translated down 1 unit.
Answer:
A) Function f is translated up 3 units.
B) Function f is translated to the right 5 units.
Step-by-step explanation:
Given functions:
[tex]f(x)=\sqrt[3]{x+4}[/tex]
[tex]g(x)=\sqrt[3]{x-1}+3[/tex]
To transform function f to function g, first subtract 5 from the x:
[tex]\begin{aligned}f(x-5)&=\sqrt[3]{x-5+4}\\&=\sqrt[3]{x-1}\end{aligned}[/tex]
Now add 3 to the function:
[tex]f(x-5)+3=\sqrt[3]{x-1}+3[/tex]
When a number "n" is subtracted from the x variable of a function, the function is translated "n" units to the right.
When a number "n" is added to a function, the function is translated "n" units up.
Therefore, the transformations performed from function f to function g are:
Function f is translated to the right 5 units.Function f is translated up 3 units.The volume of a gas halved during an adiabatic compression that increases the pressure by a factor of 2.5 What is the specific heat ratio?
A ratio in mathematics displays how often one number occurs in another and the given situation's specific heat ratio is 1.24.
What is the ratio?In mathematics, a ratio shows how frequently one number appears in another.
For instance, the ratio of oranges to lemons in a fruit plate would be eight to six if there were eight oranges and six lemons.
Oranges make up 8:14 of the total fruit, whereas lemons make up 6:8 of the total fruit.
So, e are informed that the volume is halved, and the pressure increases by a factor of 2.5.
We shall therefore have:
PVγ = 2.5P(0.5V)γ
We'll condense this to:
(1/0.5)γ = 2.5
γ = In2.5/In2
γ = 1.32
The volume temperature relation is written as follows if the volume expands in an adiabatic process:
T1V1∧γ-1 = T2V2∧γ-1
T1V1∧1.32-1 = T2(0.5V1)∧1.32-1
Condensing this results in:
T₁ = 1.24T₂
Therefore, a ratio in mathematics displays how often one number occurs in another and the given situation's specific heat ratio is 1.24.

A z-score is a quantitative measure obtained when a data point from a normal population with mean μ and standard deviation
σ is transformed. It describes the position of the data point representing its distance from the average value of the normal population measured in number of standard deviations. It is given by:
z =(X − μ)/σ
A standard normal table (z-score table) provides the probability to the left of the z-score so obtained.
Number of randomly selected steady smokers is, n=100.
Sample mean is, M=$20.
The population standard deviation is, σ = $5.
To compute the probability that a sample of 100 steady smokers spend between 19 and 21.
Using the definition of a z-score, computing the z-score for X =$19,
z =(X − μ)/σ /[tex]\sqrt{n}[/tex]
[tex]z = \frac{19-20}{5}/\sqrt{100}[/tex]

three consecutive even integers are such that the sum of the smaller two is 52 less than three times the largest. what are the integers?
Three consecutives even integers are 42, 44, and 46.
The three consecutives even integers can be represented as x, x+2, and x+4. We can create an equation to solve for x, using the given information.
3(x+4) = 52 + x + (x+2)
3x + 12 = 54 + 2x
x = 42
Therefore, the three consecutives even integers are 42, 44, and 46. To explain this answer, we can use the equation we created. We know that the sum of the smaller two integers is 52 less than three times the largest. We can represent this as 3(x+4) = 52 + x + (x+2). We can then solve for x by subtracting 2x from both sides and adding 12 to both sides, resulting in x = 42. This means that the three consecutives even integers are 42, 44, and 46.

Dottie went to the movies with her friends. She bought a soda for $2.35, a pack of bubble gum for $1.15, and a chocolate bar for $1.65. How much did Dottie spend in total?
Answer:
Step-by-step explanation:
The candy bar cost, in dollars, is $1.05
Say the price of a piece of bubble gum is x.
This means that we can represent our scenario with the equation (x+1)+x=1.10, with (x+1) representing the price of a candy bar.
We can then solve from there.
We have given that,
(x+1)+x=1.10
Simplify above expression
2x+1=1.10
2x=0.10 - Subtract From Both Sides
x=0.05 - Divide From Both Sides
So now we have the price of the piece of bubble gum, but we want the cost of the candy bar.
What is the cost?
Cost is the value of money that a company had to spend to produce its goods or services.
Fortunately, we know it costs one dollar more than the piece of bubble gum, so just do 0.05 + 1. This means our candy bar costs $1.05.

suppose that a single die with 6 sides (numbered 1, 2, 3, ... , 6) is rolled twice. what is the probability that the sum of the two rolls equals 4 ?
The probability that the sum of the two rolls equals 4 is 1/12.
Given in the question that a single die with 6 sides is rolled twice, we have to calculate the probability that the sum of the two rolls equals 4.
the set of possible outcomes when we roll a die are {1,2,3,4,5,6}
So when we roll two dice there are 6 × 6 = 36 possibilities
The number of possible combinations that will result in a sum of 4 is (1, 3), (2, 2), and (3, 1). Since there are 6 possible outcomes for each die, the probability of rolling a specific combination is 1/36. There are 3 combinations that will result in a sum of 4, so the probability of rolling a sum of 4 is 3/36 or 1/12.

3.35x + 115 = 3.25x + 125
For the given expression 3.35x + 115 = 3.25x + 125 the value of x is 100.
What is an equation?A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.
A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7. Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero.
The given expression is:
3.35x + 115 = 3.25x + 125
Regroup all the terms with variable x on one side of the equation:
3.35x - 3.25x = 125 - 115
0.1x = 10
x = 100
Hence, for the given expression 3.35x + 115 = 3.25x + 125 the value of x is 100.

the distance from the ground of a person riding on a ferris wheel can be modeled by the equation d equals 20 times the sine of the quantity pi over 30 times t end quantity plus 10 comma where d represents the distance, in feet, of the person above the ground after t seconds. how long will it take for the ferris wheel to make one revolution?
It takes approximately 26.56 seconds for the ferris wheel to make one revolution.
The ferris wheel makes one complete revolution when the distance of the person above the ground returns to the original value after completing a full circle.
This occurs when the sine function returns to its maximum value, which is 1.
Thus, we have the following equation:
20 * sin(π/30 * t) + 10 = 20
Solving for t,
we will get:
sin(π/30 * t) = 0.5
Taking the inverse sine of both sides:
(π/30 * t) = sin^-1(0.5)
Multiplying both sides by 30/π,
we will get the following:
t = (30/π) * sin^-1(0.5)
Now solving the value of t
We will get it as: t ≈ 26.56 seconds.

a six foot person walks from the base of a streetlight directly toward the tip of the shadow cast by the streetlight. when a person is 16 feet from the streetlight and 5 feet from the tip of the streetlight's shadow, the person's shadow starts to appear beyond the streetlight's shadow. what is the height of the streetlight?
The height of the streetlight is 30 feet.
Let's call the height of the streetlight "h".
When the person is 16 feet from the streetlight, the length of their shadow will be 16 feet * (6 feet / h) = 96 feet / h.
When the person is 5 feet from the tip of the streetlight's shadow, the length of the streetlight's shadow will be h * (16 feet / 5 feet) = 3.2 * h.
Since the length of the person's shadow starts to appear beyond the streetlight's shadow when they are 5 feet from the tip of the streetlight's shadow, we know that 96 / h > 3.2 * h.
Solving for h, we get:
96 / h > 3.2 * h
96 > 3.2h
30 > h
So, the height of the streetlight is less than 30 feet.
To determine the exact height of the streetlight, we can use the equation:
96 / h = 3.2 * h
96 = 3.2h
30 = h
