There is really nothing infinite in real life. But there are several cases where for practical purposes, "infinity" is almost the same as "very large". One example is in optics, where it is not so much the distance from the lens to the object that matters, but the RECIPROCAL of the distance. In this distance, since the reciprocal of a very large number is close to zero, a far-away object (e.g., the Sun) can be approximated as "infinitely far away".
alkenes can be polymerized into polymers (plastics), or used as fuels.
The integration of application is used in real life when applied to the psychology of group dynamics and the effects of bullying to weaker members of a group.
No applications in the real life; francium is only an object of studies in specialized research laboratories.
Matrices can be used to collect data. They can also be used in cryptography--the practice and study of hiding information.
Sonograms, dog whistles, Sonar.
One of the applications is for mooring yachts. You can find cleats on the deck of the boats. A rope is tighten to the cleat.
it was used for conveyor belts
Bismuth is used in a variety of real-life objects, including pharmaceuticals (such as Pepto-Bismol), cosmetics, pigments, and low-melting alloys for fire sprinkler systems. It is also used in some soldering applications.
Proportions are used in real life to determine prices of things.
An infinite-dimensional Hilbert space is a mathematical concept that has properties such as being complete, having an inner product, and being separable. It is commonly used in quantum mechanics and functional analysis to study functions and vectors in an infinite-dimensional space. Applications include quantum mechanics, signal processing, and machine learning.

Ultrasonic sound is used in medical imaging for procedures like ultrasound scans. It is also used in industrial applications for cleaning, welding, and material testing. Additionally, ultrasonic sensors are used in automotive parking assistance systems.
