Answer:
3 and 12
Step-by-step explanation:
let the 2 numbers be x and y then
x + y = 15 → (1)
xy = 36 → (2)
From (1) : y = 15 - x → (3)
substitute y = 15 - x into (2)
x(15 - x) = 36
15x - x² = 36 ( subtract 36 from both sides )
15x - x² - 36 = 0 ( multiply through by - 1 and arrange in standard form )
x² - 15x + 36 = 0 ← in standard form
(x - 3)(x - 12) = 0 ← in factored form
equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 12 = 0 ⇒ x = 12
substitute these values into (3) for corresponding value of y
x = 3 → y = 15 - 3 = 12
x = 12 → y = 15 - 12 = 3
Hence the 2 numbers are 3 and 12
Answer:
Matrices are a useful way to represent, manipulate and study linear maps between finite-dimensional vector spaces (if you have chosen basis).
Matrices can also represent quadratic forms (it's useful, for example, in analysis to study hessian matrices, which help us to study the behavior of critical points).
W=0, W=1: reason; the question is asking for what w is, so the logical answer is gonna be 0,1 because w is less than 2
