5. stephania lives in broderick, saskatchewan, and plans to buy a truck. she has two options:

option a: she can purchase a new truck, with only basic features, for $22 789.00 plus 5%
gst and 5% pst.

option b: she can buy a 5 year-old truck with approximately 120 000 km on it, but with
many upgraded features, for the same price ($22 789) plus 5% gst (pst is not charged on
used vehicles in saskatchewan)

a) calculate how much stefania would have to pay for each option.

b) give one advantage and one disadvantage for each option.

Could these triangles be congruent? yes, if ab - deyes, if bc = 7yes, if ab - efno, because the hypotenuses must have different lengths

What is (2.5a^8n)^3 · (0.4^7n)^3 can you plz simplify this quickly offering lots of points

Ece 202: problem set 1 due: june 14, 2019 (friday) the first 3 questions of this homework assignment covers some fundamental mathematical concepts that will play a role in this course. the remaining questions are on basic signals and laplace transforms. 1. a review of complex numbers. (a) compute the magnitude and the phase of the complex numbers −4 +j, and write them in polar form (i.e., of the form rejθ). also, plot the complex number in the complex plane. (b) simplify the complex number 1 4 − √ 1 2 − j √ 2 22 and write them in cartesian form. (c) consider the complex number s = z1z2 · · ·zm p1p2 · · · pn , where each zi is a complex number with magnitude |zi | and phase ∠zi , and each pi is a complex number with magnitude |pi | and phase ∠pi . write the magnitude and phase of s in terms of the magnitudes and phases of z1, z2, . . , zm, p1, p2, . . , pn. 2. a review of differentiation. (a) find df dx for the following functions. i. f(x) = (1−4x) 2 √ x . ii. f(x) = √ 1 + tan x. (b) find dy dx for the equation e x sin y + cos2 x cos y − x 3 = 0.
