🎓 בגרות 472 חורף 2026 שאלה 3-גידול ודעיכה.

📌What's in the video: In this video, we will solve question 3 from Questionnaire 472 (4 units) Winter 2026, which deals with growth and decay problems. We will analyze the cooling process of strawberry jam and plum jam in the refrigerator, and learn how to infer decay rates from a qualitative comparison. We will calculate the decay bases (q) for each jam, find the time required to reach a certain temperature using logarithms (ln), and calculate the initial temperature of one of the jams. Finally, we will solve a complex exponential equation to find the exact point in time at which the temperatures of the two jams become identical. 📌 Link to the question in the video: https://kibinimatika.org/472H2026 📌For all the solutions to this matriculation exam on the Kibinimatika website: https://kibinimatika.org/4722026PITARON 💬 Join our community on Discord - for questions, answers and guidance: 🔗   / discord   🌐 Our website:https://kibinimatika.org 🔗 For all our study groups and community: https://kibinimatika.org/%d7%94%d7%a7... 📚Our groups on Telegram:https://t.me/ovadgroups 🔥Oved Lev's update channel Ari: https://whatsapp.com/channel/0029VbAD... 🧮Link to playlist:    • 🎓 פתרוןבגרות 472 חורף 2026 שאלה 2-וקטורים.   Like, comment and subscribe to the channel help the content reach more students!
