Express the complex number z = -4+3i in polar form: r(cos⁡(θ)+i sin(θ)).

5( cos(- 0.64)+ sin(-0.64))

Step-by-step explanation:

Given:

z = -4+3i

θ=

Polar form=r(cosθ+ sinθ)=> 5( cos(- 0.64)+ sin(-0.64))

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
