Answer:
(a) 12∠0.1
(b) 3∠-0.1
(c) (1/3)∠-0.1
Step-by-step explanation:
In this answer, we will use the notation r∠φ to identify the "r-part" and the "φ-part" of your polar-form complex numbers.
Given: z = 3∠0.1
(a) 4z = 12∠0.1 . . . . . the r-part is multiplied by the scalar
(b) z* = 3∠-0.1 . . . . . the conjugate is formed by negating the angle
(c) 1/z = (1/3)∠-0.1 . . . . the reciprocal inverts the magnitude and negates the angle.
I got the number

Answer:
A) is 1/25
Step-by-step explanation:
Slope is rise over sun, hence... 2/50 (rise/run or length)
Then you simplify... 1/25
Answer:
12/23
Step-by-step explanation:
Keith and his Dog moved 23miles around the park
They jogged for 12miles
Fraction of distance jogged by Keith and his dog = distance jogged / total distance moved around the park
That’s 12/23
Answer:
145 each because the total 'area' of a circle is 360 like a square. 35+35 is 70. 360-70=290/2
