Answer:
let z=3-i
|z|=square root 10 r=square root 10
Ø=-pi/6
z=sqr 10 × e^i×pi/6
z=sqr 10(cos(-pi/6) +isin(-pi/6))
First, find the amount of time is taken to travel 1 mile :
time taken to travel 1 mile = 20/6 = 3 ⅓ mins
hence, time taken to travel 9 miles = 3 ⅓ x 9 = 30 mins
time taken to travel 10 miles = 3 ⅓ x 10 = 33 ⅓ mins
Answer:
x=y=z=106
Step-by-step explanation:
The upper line is a straight line, so x+74=180, x=106.
y and x are equal in measure as it's a pair of parallel lines and z=y as they are alternate interior angles
The answer to the equation is 8x-1
