Kindly solve for what is asked. Please make it legible as you can. It will be a big help for me to be able to understand. If possible, kindly also include a small explanation of how or what is the process. Thanks a lot!

Assessment 1. Find the particular solution of the differential equation determined by the initial conditions: dx 2 d ikc=4(1+3y)2 ;x=-1 and =-2 when y =1 d)" dy 2. A particle is moving along a line in such a way that if v centimeters per second is the velocity of the particle at t seconds, then v = 9sin(372t), where the positive direction is to the right of the origin. If the particle is at the origin at the start of the motion, find its position at 4.8 seconds. 3. A stone is dropped from the top of the Washington Monument 555 ft high.
