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
Well first you have to get 0.4 and turn that decimal into a fraction which will be 2/5 and that fraction is already at its simplest form and cant be reduced so your answer is both 0.4 and 2/5.

Answer:
12 pounds
Step-by-step explanation:
One quantity is asked for, so it is convenient to let a variable represent that. We can use x to represent pounds of chocolate. Then the total cost of the mix is ...
19.30·x + 3.50·18 = 9.82·(x +18) . . . . cost of chocolate + cost of trail mix
9.48·x = 113.76 . . . . . . simplify, subtract 63+9.82x
113.76/9.48 = x = 12 . . . . . . divide by the coefficient of x
The owner needs to mix 12 pounds of chocolate. (no rounding necessary)
