- cos ( 1/2 x + 1/5 π ) = 0 ( and because if cos α = 0, α= π/2 + k π, k ∈ Z )
1/2 x + π/5 = π/2 + k π, k ∈ Z
1/2 x = π/2 - π/5 + k π / * 2
x = π - 2π/5 + 2 k π
x = 3/5 π + 2 k π = 0.6 π + 2 k π
Answer:
If k = 0: x 1 = 0.6 π = 3π/5
k = 1 : x 2 = 2.6 π = 13π/5

y=(-2/3)x+8
Answer: In 7 years, Ms Acosta will earn $37,734.7
Step-by-step explanation:
From the information given, we find the increase using exponential growth formula
A= P(1+r)^t
Where p= the starting amount on the contract, given as $34000
r = rate, given at 1.5% = 1.5/100 = 0.015
t = time, given as 7years
Plug the values into the formula:
A = 34000(1 + 0.015) ^7
= 34000 (1.015)^7
34000 x 1.1098
A= $37,734.7
In 7 years, Ms Acosta will earn $37,734.7.
