Find all eigenvalues of a without using a calculator. show your work. b. (6 points) for each eigenvalue, find a basis for the corresponding eigenspace. c. (4 points) find matrices p and d such that a= pdp.

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.
