Explanation Given: The system is d y d t = 2 x − y d y d t = 3 x − 2 y + 4 t . Calculation: Express the linear system d y d t = 2 x − y and d y d t = 3 x − 2 y + 4 t in the matrix form. X ′ = ( 2 − 1 3 − 2 ) X + ( 0 4 ) t ...... ( 1 ) The homogeneous system from the matrix form is X ′ = ( 2 − 1 3 − 2 ) X . The characteristic equation of the coefficient matrix can be expressed as follows: ( A − λ I ) = ( 2 − 1 3 − 2 ) − λ ( 1 0 0 1 ) = ( 2 − 1 3 − 2 ) − ( λ 0 0 λ ) = ( 2 − λ − 1 3 − 2 − λ ) Express the determinant of the coefficient matrix and equate to zero to obtain the Eigen values. | ( A − λ I ) | = | 2 − λ − 1 3 − 2 − λ | ( 2 − λ ) ( − 2 − λ ) + 3 = 0 λ 2 − 1 = 0 λ = ± 1 Hence, from the above results, the two Eigen values are λ 1 = + 1 and λ 2 = − 1 . For λ 1 = 1 , the components of Eigen vector are calculated as follows: | 2 − λ − 1 3 − 2 − λ | = | 2 − 1 − 1 3 − 2 − 1 | ( λ 1 = 1 ) = | 1 − 1 3 − 3 | K 1 − K 2 = 0 3 K 1 − 3 K 2 = 0 where, K 1 , K 2 are the components of the Eigen vector. From the above expression K 2 = K 1 . Therefore, the corresponding Eigen vector is K 1 = ( 1 1 ) . For λ 2 = − 1 , the components of Eigen vector are calculated as follows: | 2 − λ − 1 3 − 2 − λ | = | 2 + 1 − 1 3 − 2 + 1 | ( λ 1 = − 1 ) = | 3 − 1 3 − 1 | 3 K 1 − K 2 = 0 3 K 1 − K 2 = 0 From the above expression K 2 = 3 K 1 . Therefore, the corresponding Eigen vector is K = ( 1 3 ) . Hence, the solution vectors of the given solution are X 1 = ( 1 1 ) e t , X 2 = ( 1 3 ) e − t . The solution vectors in the form of the matrix ϕ ( t ) can be expressed as follows: ϕ ( t ) = ( e t e − t e t 3 e − t ) Express the determinant of the matrix ϕ ( t )

5) You are purchasing a game for $30. You have a 5% off coupon and sales tax is 5%. What will your final price be? Does it matter if you take off the coupon first or add in the tax first? 6) You have ten coupons that allow you to take 10% off the sales price of a jacket, and for some strange reason, the store is going to allow you to use all ten coupons! Does this mean you get the jacket for free? Let's really think about what would happen at the checkout. First, the teller would scan the price tag on the jacket, and the computer would show the price is $100. After the teller scans the first coupon, the computer will take 10% off of $100, and show the price is $90. (Right? Think about why this is.) Then after the teller scans the second coupon, the computer will take 10% off of $90. (a) Continue this reasoning to fill in the table below showing the price of the jacket (y) after you apply x coupons. (b) Make a graph showing the price of the jacket from x = 0 to x = 10 coupons applied.…
