CD/ ED = DG / DF
48 / (5x - 2) = 40 / (2x + 7)
48 (2x + 7) = 40 (5x - 2)
96x + 336 = 200x - 80
200x - 96x = 336 + 80
104x = 416
x = 4
16.
ST / PL = TU / LM
(x + 1) / 72 = (2x - 3) / 99
99 (x + 1) = 72 (2x - 3)
99x + 99 = 144x - 216
144x - 99x = 99 + 216

what is distributional hypothesis in the context of distributional semantics? give a short explanation with some examples. g
Distributional semantics develops methods for measuring and classifying semantic similarity between language elements.
To quantify and classify semantic relatedness among linguistic items based on their distributional qualities in large samples of language data, distributional semantics is a field of study. The distributional hypothesis captures the fundamental principle of distributional semantics.
The semantic theory of language usage, states that terms used and occurring in comparable situations tend to have similar meanings is the basis for the distributional hypothesis in linguistics. For instance, the words "fire" and "dog" have very different meanings and aren't typically used together in a sentence. However, the terms "dog" and "cat" are occasionally used interchangeably, suggesting that they may have a similar connotation.

What is an equation?Identifying which variables values result in equality is part of solving a variable equation. The variables for which the equation must be solved are known as unknowns, whereas the unknown values that fulfill the equality are known as equation solutions. A mathematical expression with two equal sides separated by an equal sign is known as an equation. 4 + 6 = 10. We can see 4 + 6 on the left and 10 on the right side of the equal symbol.
We already have,
1) You often purchase a grande cafe latte from Starbucks, which costs $3.65.
This formula is:
Number of days = x
Total cost after x days = 3.65x
2) You spend $300 on an espresso machine and ingredients for lattes, which cost an extra $1.35 per day.

Answer:
[tex]\textsf{1)\quad 48\;inches}[/tex]
[tex]\textsf{2)\quad$2\sqrt[3]{3}$\; inches}[/tex]
Step-by-step explanation:
Question 1Define the variables:
Let x be the length of the string.Let y be the rate of vibration of a string under constant tension.The rate of vibration of a string under constant tension varies inversely with the length of the string:
[tex]\boxed{y \propto \dfrac{1}{x} \implies y=\dfrac{k}{x}\quad\text{for a constant $k$}}[/tex]
Given values:
x = 24 inchesy = 128 times per secondSubstitute the given values of x and y into the formula and solve for k:
[tex]\implies 128=\dfrac{k}{24}[/tex]
[tex]\implies k=128 \cdot 24[/tex]
[tex]\implies k=3072[/tex]
Therefore, the equation is:
[tex]y=\dfrac{3072}{x}[/tex]
To find the length of a string that vibrates 64 times per second, substitute y = 64 into the equation and solve for x:
[tex]\implies 64=\dfrac{3072}{x}[/tex]
[tex]\implies x=\dfrac{3072}{64}[/tex]
[tex]\implies x=48[/tex]
Therefore, the length of a string that vibrates 64 times per second is 48 inches.

Question 2Define the variables:
Let y be the horsepower (hp) that a shaft can safely transmit.Let v be the speed of the shaft (in rpm).Let d be the diameter of the shaft (in inches).The horsepower that a shaft can safely transmit varies jointly with its speed and the cube of the diameter:
[tex]\boxed{y \propto vd^3 \implies y=kvd^3\quad\text{for a constant $k$}}[/tex]
Given values:
y = 45 hpv = 100 rpmd = 3 inchesSubstitute the given values of y, v and d into the formula and solve for k:
[tex]\implies 45=k \cdot 100 \cdot 3^3[/tex]
[tex]\implies 45=k \cdot 100 \cdot 27[/tex]
[tex]\implies 45=2700k[/tex]
[tex]\implies k=\dfrac{45}{2700}=\dfrac{1}{60}[/tex]
Therefore, the equation is:
[tex]y=\dfrac{vd^3}{60}[/tex]
To find the diameter of the shaft in order to transmit 60 hp at 150 rpm, substitute y = 60 and v = 150 into the equation and solve for d:
[tex]\implies 60=\dfrac{150d^3}{60}[/tex]
[tex]\implies 3600=150d^3[/tex]
[tex]\implies d^3=\dfrac{3600}{150}[/tex]
[tex]\implies d^3=24[/tex]
[tex]\implies d=\sqrt[3]{24}[/tex]
[tex]\implies d=\sqrt[3]{8 \cdot 3}[/tex]
[tex]\implies d=\sqrt[3]{8} \sqrt[3]{3}[/tex]
[tex]\implies d=\sqrt[3]{2^3} \cdot \sqrt[3]{3}[/tex]
[tex]\implies d=2\sqrt[3]{3}[/tex]
Therefore, the diameter of a shaft that transmits 60 hp at 150 rpm is 2³√3 inches.

2. loran is a long range hyperbolic navigation system. suppose two loran transmitters are located at the coordinates and , where unit distance on the coordinate plane is measured in miles a receiver is located somewhere in the first quadrant. the receiver computes that the difference in the distances from the receiver to these transmitters is 180 miles. what is the standard form of the hyperbola that the receiver sits on if the transmitters behave as foci of the hyperbola?
The path LORAN followed is hyperbolic.
The equation of the hyperbola is x²/8100 + y²/1900 = 1
Given,
These are the coordinates:
(x, y) = (-100, 0) (100, 0)
The hyperbola's center; (h, k) = (0, 0)
The following is the distance between the center and the focal points:
c = 100
Square both sides;
c² = 10000
The following is the distance between the transmitters and the receiver:
2a = 180
Divide 2 from both sides.
a = 90
Square both sides;
a² = 8100
We possess;
b² = c² - a²
This results in;
b² = 10000 - 8100
b² = 1900
A hyperbola's equation is as follows:
(x - h)²/a² + (y - k)²/b² = 1
We thus have:
(x - 0)²/8100 + (y - 0)²/1900 = 1
x²/8100 + y²/1900 = 1
As a result, the hyperbola's equation is: x²/8100 + y²/1900 = 1
