📰 Question: If $ \mathbf{a}, \mathbf{b}, \mathbf{c} $ are unit vectors with $ \mathbf{a} \cdot \mathbf{b} = \frac{1}{2} $, $ \mathbf{b} \cdot \mathbf{c} = \frac{\sqrt{3}}{2} $, find the maximum value of $ \mathbf{a} \cdot \mathbf{c} $. 📰 Solution: Let $ \theta $ be the angle between $ \mathbf{a} $ and $ \mathbf{b} $, so $ \cos\theta = \frac{1}{2} \Rightarrow \theta = 60^\circ $. Let $ \phi $ be the angle between $ \mathbf{b} $ and $ \mathbf{c} $, so $ \cos\phi = \frac{\sqrt{3}}{2} \Rightarrow \phi = 30^\circ $. To maximize $ \mathbf{a} \cdot \mathbf{c} = \cos(\alpha) $, where $ \alpha $ is the angle between $ \mathbf{a} $ and $ \mathbf{c} $, arrange $ \mathbf{a}, \mathbf{b}, \mathbf{c} $ in a plane. The maximum occurs when $ \mathbf{a} $ and $ \mathbf{c} $ are aligned, but constrained by their angles relative to $ \mathbf{b} $. The minimum angle between $ \mathbf{a} $ and $ \mathbf{c} $ is $ 60^\circ - 30^\circ = 30^\circ $, so $ \cos(30^\circ) = \frac{\sqrt{3}}{2} $. However, if they are aligned, $ \alpha = 0^\circ $, but this requires $ \theta = \phi = 0^\circ $, which contradicts the given dot products. Instead, use the cosine law for angles: $ \cos\alpha \leq \cos(60^\circ - 30^\circ) = \cos(30^\circ) = \frac{\sqrt{3}}{2} $. Thus, the maximum is $ \boxed{\frac{\sqrt{3}}{2}} $. 📰 Question: Find the vector $ \mathbf{v} $ such that $ \mathbf{v} \times \begin{pmatrix} 1 \\ 0 \\ 2 \end{pmatrix} = \begin{pmatrix} -4 \\ 6 \\ 2 \end{pmatrix} $. 📰 This Simple Blue Sage Grille Change Dug Dominates Front Yard Trend Spotlight 1904720 📰 Glasf Stock Is Set To Explodeheres Why Experts Are Talking Rally Points 1476718 📰 The Forgotten Wisdom Of Sevensage Tracks You To Total Awakening 1207429 📰 5 Unbelievable Facts That Prove Spacewave Crazy Games Are Game Changers Watch Now 5876050 📰 At Fates End 7821553 📰 Fruit Cups Finally Revealed The Hidden Hidden Gems Youve Been Missing 4972097 📰 Think Usd Drop The Usd To Thb Rate Is Shocking New Highswatch Now 7977815 📰 Chilis Happy Hour Hours 5618823 📰 Southwest Rapid Rewards Priority Credit Card 5557928 📰 Celeste Rivas Hernandez 2069346 📰 Think Walmarts Stocks Are Stuck Think Againyahoo Tells The Surprising Truth 2353088 📰 Lilo And Stitch Review Is This The Cute Classic Everyones Been Hitting Backwards About 6332426 📰 Chromakopia Tour 7252874 📰 Samurai Warriors The Unbreakable Secrets Behind Japans Greatest Warriors You Wont Believe 2642678 📰 14131 A Car Travels At A Speed Of 60 Miles Per Hour For The First Half Of A 300 Mile Trip And At 40 Miles Per Hour For The Second Half How Long Did The Entire Trip Take 9558357
