3. let a = (-1,3), b =(3, 3), c = { in € n), and d = {-1,0,1,2}. (a) [2 marks) which of the listed sets a, b, c, d are subsets of a? (b) (1 mark] calculate an d. (c) (2 marks] find a - b. express your answer as a union of two intervals. (d) [1 mark] are the sets b and c disjoint? circle: yes no

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
