Solve the problem.Wind resistance or atmospheric drag tends to slow down moving objects. Atmospheric drag varies jointly as an object's surface area A and velocity v. If a car traveling at a speed of 40 mph with a surface area of 38 ft2 experiences a drag of 228 N (Newtons), how fast must a car with 37 ft2 of surface area travel in order to experience a drag force of 305.25 N?
A. 52 mph B. 57 mph C. 55 mph D. 60 mph
Complete the square and write the equation in standard form. Then give the center and radius of the circle.x2 + y2 + 6x + 4y = 3
A. (x + 3)2 + (y + 2)2 = 16 (3, 2), r = 16 B. (x + 2)2 + (y + 3)2 = 16 (2, 3), r = 16 C. (x + 3)2 + (y + 2)2 = 16 (-3, -2), r = 4 D. (x + 2)2 + (y + 3)2 = 16 (-2, -3), r = 4
