The Ford Model A, built from 1928 to $1931,$ had a single windshield wiper on the driver's side. The total arm and blade was 10 in. long and rotated back and forth through an angle of $95^{\circ} .$ The shaded region in the figure is the portion of the windshield cleaned by the 7 -in. wiper blade. Find the area of the region cleaned to the nearest tenth.

Phosphorus (P) is an important nutrient for plant growth. In an experiment, Arabidopsis thaliana plants grown under phosphorus-sufficient and phosphorus-starved conditions for six weeks were observed. At the end of six weeks, it was found that the plants grown under phosphorus-starved conditions were much smaller overall. Which of the following is the most likely reason for this observation? A. The phosphorus-starved plant was unable to synthesize both the required proteins and nucleic acids, limiting growth. B. The phosphorus-starved plant was unable to synthesize both the required nucleic acids and lipids, limiting growth. C. The phosphorus-starved plant was unable to synthesize both the required proteins and lipids, limiting growth. D. The phosphorus-starved plant was unable to synthesize both the required proteins and carbohydrates, limiting growth.
