Solve the problem. Water is discharged from a pipeline at a velocity v given by v = 1.096p(1/2), where p is the pressure (in psi). If the water pressure is changing at a rate of 0.251 psi/second, find the acceleration (dv/dt) of the water when p=32 ps O 778.09 ft/s² O 24.32 ft/s² O 96.87 ft/s2 O 31 ft/s² Question 3 Solve the problem. In the formula A(t) = Agek, A(t) is the amount of radioactive material remaining from an initial amount A, at a given time t and k is a negative constant determined by the nature of the material. A certain radioactive isotope has a half-life of approximately 1.950 years. How many years would be required for a given amount of this isotope to decay to 75% of that amount? 3.900 yr 809 yr 734 vr 487.9 Vr
