Analyze the graph below to answer the following questions. 4 Velocity (mis) Time (s) -7 -8 Calculate the acceleration of the object during the four different sections of the graph. Section 1, from 0-2 s a = -1.5 x unit m direction: backward/negative Section 2, from 2-4 s a = unit m direction: no direction, its not accelerating - Section 3, from 4-6 s a = unit m direction: backward/negative Section 4, from 6-10s a = unit m direction: no direction, its not accelerating -

Define T: M 'n, n R by T(A) = a 11 + a22 + ... + ann (the trace of A). Prove that T is a linear transformation. + + 1 = = O + ... + Let A and B be to matrices in Mn, n, and let the entries of A, B be denoted ajj and bij, respectively, for 1 si,j sn. By matrix addition, we know that the entries of the matrix A + B are of the form ---Select--- V for 1 si,j s n. By the definition of T and the commutative and associative property of addition, we have which of the following? T(A + B) (a, + b ) + ... + (an + bn) (a1 + ... + an) + (61 + ... + b) T(A) + T(B) T(A + B) (a1.b7) + ... + (an:bn) = (a1 + ... + an) + (61 + bn) T(A) + T(B) T(A + B) (a11 + b11) (a11 + ... + ann) + (611 + ... + bnn) = T(A) + T(B) T(A + B) (211.611) + ... + (ann · bnn) = (a11 + ... + a, ann) (611 + ... + bnn) T(A) + T(B) = + ... + (ann + bnn) O = + + = 1 si, jsn. By the definition of T and the = ca 11 nn = ... + a = ca 11 nn = Now, let c be a scalar. By scalar multiplication, we know that the entries of the matrix CA are of the form ---Select--- distributive property of multiplication, we have which of the following? T(CA) . ca = c(a11 + ann) cТ(А) T(CA) + ... + ca c(a11 + ... + ann) = CT(A) T(CA) can ca + + an) cТ(А) T(CA) = ca 1 can c(a1 + ... + an) = cT(A) = ca 1 + ... + ca ... = = = Therefore, T is a linear transformation.
