Deet r 2/3 12= -2/3 2/3 0-1 1/3 12/31 1/3 , a) let b={0,,uz? and letw-span b. verify that b is an or thonormal basis for wo b) let u= [0, uz]. compute out c) compute prosu g. d) compute outs.

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

the answer is c.

step-by-step explanation:

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
