Accessible descriptiоn: The figure indicаtes оn the y-аxis price аnd cоsts (dollars per unit) and on the x-axis the quantity (per day). Depicted in the figure is a marginal revenue curve, which is equal to $40 per unit for any quantity produced. Also depicted are a marginal cost curve and average total cost curve, which are both u-shaped. Marginal costs decrease through points (20,30) and then increases through the point (30,40). Average total cost decreases through the point (20,30) and then increases. f1q53g1.jpg The figure above shows a perfectly competitive firm. To maximize its profit, the firm will

A 45-yeаr-оld оffice wоrker reports grаduаl onset of right shoulder pain over the past six months. The patient spends long hours at a desk and has noticed increasing stiffness and discomfort in the upper back and neck. During the evaluation, the supervising physical therapist notes a forward head posture (FHP) and rounded shoulders. The patient reports difficulty reaching overhead and occasional tingling in the right arm. Multiple-Choice Questions: 1. Postural Impact on Shoulder Biomechanics: How does forward head posture (FHP) and rounded shoulders affect scapular positioning and GH joint mechanics? A. It promotes scapular retraction, improving GH stability. B. It causes scapular protraction, reducing subacromial space and increasing impingement risk. C. It increases thoracic extension, allowing for greater shoulder mobility. D. It has minimal effect on shoulder function. 2. Risk for Shoulder Pathology: Which of the following shoulder pathologies is this patient most at risk for due to their posture? A. Anterior shoulder instability and SLAP lesion B. Subacromial impingement syndrome and rotator cuff tendinopathy C. Posterior shoulder dislocation and labral tear D. Long head of the biceps rupture and AC joint sprain 3. Therapeutic Interventions: Which of the following exercises would best help improve posture and restore proper shoulder mechanics? A. Upper trapezius strengthening, latissimus dorsi stretching, and pectoralis major stretching B. Pectoralis major strengthening, upper trapezius stretching, and latissimus dorsi strengthening C. Scapular protraction exercises, upper trapezius activation, and anterior deltoid strengthening D. Overhead pressing, push-ups with protraction, and heavy chest pressing 4. Patient Education & Ergonomics: What ergonomic and postural corrections should be recommended for this patient? A. Encourage prolonged sitting with a soft couch for lumbar support and frequent head tilting B. Adjust workstation to position screen at eye level, maintain neutral spine posture, and take breaks every 30-60 minutes C. Use a pillow behind the neck while sitting to maintain a relaxed position D. Focus on lumbar lordosis only, as it is the main contributor to shoulder dysfunction
