Let d be the square 0,1] x [0,1] let a -(a1,a2) and b (bi, b2) be nonzero vectors such that neither is a multiple of the other let d be the parallelograrn with vertices (0,0), (a1,a2), (b1mg), and (abi, a b). that is, d is the parallelogram with vertices 0, a, b, and ah. (a) find a linear map t r r taking d onto d. (write the expression for t(, ci) let d be a parallelogram with vertices (0, 0), (1, 3), 2, 0), 3). let d0, x [0, find a linear map 7 such that t(d) d

answer: i think it is (1,-2)

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west

your answer is

a.

5

step-by-step explanation:

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
