3cis(5pi/4) in polar form
madreJ [45]
Rectangular form:
z = -2.1213203-2.1213203i

Angle notation (phasor):
z = 3 ∠ -135°

Polar form:
z = 3 × (cos (-135°) + i sin (-135°))

Exponential form:
z = 3 × ei (-0.75) = 3 × ei (-3π/4)

Polar coordinates:
r = |z| = 3 ... magnitude (modulus, absolute value)
θ = arg z = -2.3561945 rad = -135° = -0.75π = -3π/4 rad ... angle (argument or phase)

Cartesian coordinates:
Cartesian form of imaginary number: z = -2.1213203-2.1213203i
Real part: x = Re z = -2.121
Imaginary part: y = Im z = -2.12132034

Write L if it is likely to happen and U if unlikely to happen.
maria [59]

Answer:

Probabilities

        Likely to happen (L)      Unlikely to happen (U)

a.      4/5                                 5/8

b.     3/5                                  3/8

c.     4/5                                  4/7

d.    0.3                                  0.09

e.    5/6 and 4/5                   2/3

Step-by-step explanation:

Probabilities in Percentages:

a. The probability of 4/5 = 80% and 5/8 = 62.5%

b. The probability of 3/8 = 37.5% and 3/5 = 60%

c. The probability of 4/5 = 80% and 4/7 = 57%

d. The probability of 0.3 = 30% and 0.09 = 9%

e. The probability of 2/3 = 67% and 4/5 = 80% and 5/6 = 83%

b) To determine the relative values of the fractional probabilities, it is best to reduce them to their fractional or percentage terms.  When this is done, the relative sizes become obvious, and then, comparisons can be made.

Susan drove to visit a friend. She drove 345
padilas [110]

Answer:

Average\ Speed = 60 mi/hr

Step-by-step explanation:

Given

Distance = 345\ miles

Time = 5\ hours\ 45\ minutes

Required

Determine the average speed

This is calculated as thus:

Average\ Speed = \frac{Distance}{Time}

Convert time to hour:

Time = 5\ hours\ 45\ minutes

Time = 5\ hours + \frac{45}{60}\ hour

Time = 5\ hours + \frac{3}{4}\ hour

Time = \frac{20 + 3}{4}\ hours

Time = \frac{23}{4}\ hours

Time = 5.75\ hours

Average\ Speed = \frac{Distance}{Time}

Average\ Speed = \frac{345}{5.75}

Average\ Speed = 60 mi/hr
