📰 Question: A science communicator observes that the number of views $ V(t) $ on a video grows quadratically over time $ t $ (in days). If $ V(1) = 120 $, $ V(2) = 200 $, and $ V(3) = 300 $, find $ V(4) $. 📰 Solution: Assume $ V(t) = at^2 + bt + c $. From $ V(1) = a + b + c = 120 $, $ V(2) = 4a + 2b + c = 200 $, $ V(3) = 9a + 3b + c = 300 $. Subtract first equation from the second: $ 3a + b = 80 $. Subtract second from the third: $ 5a + b = 100 $. Subtract these: $ 2a = 20 $ → $ a = 10 $. Then $ 3(10) + b = 80 $ → $ b = 50 $. From $ a + b + c = 120 $: $ 10 + 50 + c = 120 $ → $ c = 60 $. Thus, $ V(t) = 10t^2 + 50t + 60 $. For $ t = 4 $: $ V(4) = 10(16) + 50(4) + 60 = 160 + 200 + 60 = 420 $. Final answer: $ oxed{420} $. 📰 Question: An underwater robot’s depth $ d(t) $ (in meters) satisfies $ d(t) = pt^3 + qt^2 + rt + s $. Given $ d(1) = 10 $, $ d'(1) = 12 $, $ d(2) = 28 $, and $ d'(2) = 30 $, find $ d(0) $. 📰 Verizon Wireless For Businesses 📰 Rates For Fha Loans 📰 How To Change Nickname On Xbox 9654445 📰 The Rmr Group 📰 Excel Filter Function 📰 Multi Extractor 📰 From First Kick To Big Belly These Maternity Shoots Will Make Your Heart Skip A Beat 378782 📰 Pokmon Violet Dlc You Need This Secret Masterpiece Before It Disappears 3794148 📰 2 Step By Step Guide Unlock Classroomlinks Hidden Power To Boost Team Collaboration 3328363 📰 How Much Can You Contribute To Hsa 📰 From Flappers To Fame The Untold Mae West Tale You Have To See 4551110 📰 Map Of French Quarter New Orleans Louisiana 📰 Sudden Update Wwf Smackdown 2 Gameshark Codes Activators And It S Going Viral 📰 Best Cell Phone Unlimited Plan 📰 What Is An Sdk
