Question
Homework: When a circular plate of metal is beated in an oven its radius increases at rate of 0.01 cm/min. At what rate is the plate's area increasing when its radius is 50 cm. 2. The length () of rectangle is decreasing at the rate of 2 cm/sec while the width (w) is increasing at the rate of 2 cm/sec. When I-12 cm and w-5 cm, lo find the rate of change of: (a) the area (b) the perimeter (c) the length of the diagonal of the rectangle. 3. The commercial jets at 40 000 ft are flying at 520 mph along straight-line courses that cross at right angles. How fast is the distance between the planes closing when plane A is 5 mi from the intersection point and plane B is 12 mi from the intersection point.
