40 = n-.40n
40 =n(1-.4)
40 = n(.6
divide by .6 on each side
40/.6 =n
n=66 2/3
Answer:
- 25 and - 623
Step-by-step explanation:
Using the term to term rule with u₀ = - 3 , then
(a)
u₁ = u₀³ + 2 = (- 3)³ + 2 = - 27 + 2 = - 25
(b)
u₂ = u₁³ + 2 = (- 25)³ + 2 = - 625 + 2 = - 623
Answer:
h = 2 ft
Step-by-step explanation:
V = lwh
144 = (9)*(8)*(h)
144 = (72)*h
h = 144/72
h = 2 ft
