(a) Explanation Given: Alzheimer’s cases in people with ages 85 or more was 2 million in 2004 and is projected to be 3 million in 2025 and 8 million in 2050 . Consider, x = 0 corresponds to 2000 . Explanation: Consider the quadratic equations: f ( x ) = a x 2 + b x + c . Where, y is the number of Alzheimer’s cases in millions, and x = 0 representing the year 2000 . Substitute the values of f ( x ) from the provided information, Hence, x 4 25 50 y 2 3 8 Therefore, use these information, a ( 4 ) 2 + b ( 4 ) + c = 2 a ( 25 ) 2 + b ( 25 ) + c = 3 a ( 50 ) 2 + b ( 50 ) + c = 8 Therefore, 16 a + 4 b + c = 2 625 a + 25 b + c = 3 2500 a + 50 b + c = 8 Therefore, the system of equation can be written as in the matrix form as: [ 16 4 1 (b) To determine The number of people who are in the age of 85 or older and will have Alzheimer’s disease in 2020 and in 2034 . (c) To determine The number of peoples at your age or older are expected to have Alzheimer’s disease when in the year you turn 85 .

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

R denotes the field of real numbers, Q denotes the field of rationals, and Fp denotes the field of p elements given by integers modulo p. You may refer to general results from lectures. Question 1 For each non-negative integer m, let R[x]m denote the vector space consisting of the polynomials in x with coefficients in R and of degree ≤ m. x²+2, V3 = 5. Prove that (V1, V2, V3) is a linearly independent (a) Let vi = x, V2 = list in R[x] 3. (b) Let V1, V2, V3 be as defined in (a). Find a vector v € R[×]3 such that (V1, V2, V3, V4) is a basis of R[x] 3. [8] [6] (c) Prove that the map ƒ from R[x] 2 to R[x]3 given by f(p(x)) = xp(x) — xp(0) is a linear map. [6] (d) Write down the matrix for the map ƒ defined in (c) with respect to the basis (2,2x + 1, x²) of R[x] 2 and the basis (1, x, x², x³) of R[x] 3. [5]

Question 4 (a) The following matrices represent linear maps on R² with respect to an orthonormal basis: = [1/√5 2/√5 [2/√5 -1/√5] " [1/√5 2/√5] A = B = [2/√5 1/√5] 1 C = D = = = [ 1/3/5 2/35] 1/√5 2/√5 -2/√5 1/√5' For each of the matrices A, B, C, D, state whether it represents a self-adjoint linear map, an orthogonal linear map, both, or neither. (b) For the quadratic form q(x, y, z) = y² + 2xy +2yz over R, write down a linear change of variables to u, v, w such that q in these terms is in canonical form for Sylvester's Law of Inertia.
