Consider the equation y" - y' – 2y = 8t2. Which of the following is FALSE? 7- In order to find the general solution, we need to find a particular solution to the equation and add to the complementary solution ce 2t O t'is a solution to the equation. -4t2 + 4t – 6 is a particular solution. 2020e-t + 2021e2t-4t2 + 4t – 6 is a solution. If Y, Y2 are two solutions to the equation, then Y1- Y2 = cje+ c2e" for some constants c1, C2. 4e2t – 4t2 +4t- 6 is a solution. y" – y' - 2y = 0 is called the associated homogeneous equation.

-5V12x +17 b. 621x - 14 + 8 = 5 a. 2. Show how to solve the equation. Remember to check for extraneous solutions x - 5 = V10 - 2x

If a projectile is launched vertically upward from the ground with an initial velocity of 90 ft per sec, neglecting air resistance, its height s (in feet) above the ground t seconds after projection is given by s= - 161" + 90t. Which equation should be used to determine the time ai which the height of the projectile reaches 20 ft? Choose the correct answer below. O A. s= - 16(20) + 90 O B. 20= - 16t +90t O C. 20= -16t Click to select wour answer 10:36 AM 2/19/202
