The dye dilution method is used to measure cardiac output with 5 mg of dye. The dye concentrations, in mg/L, are modeled by c(t) = 27te^−0.8t, 0 ≤ t ≤ 10, where t is measured in seconds. Find the cardiac output. (Hint: Integration by parts is required. Round your answer to four decimal places.)

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400

Factor the polynomial 4x4 – 20x2 – 3x2 + 15 by grouping. what is the resulting expression? (4x2 + 3)(x2 – 5) (4x2 – 3)(x2 – 5) (4x2 – 5)(x2 + 3) (4x2 + 5)(x2 – 3)

Ming says that 0.24 > 1/4 because 0.24= 2/4. which best explains mings error
