Answer:
x<168
Step-by-step explanation:
Answer:
a) -4
b) +343
Step-by-step explanation:
a) 10 shares - loss $40
1 share --- ?
? = 40 / 10 = 4 decrease
b) each week 7 members increase for 49 weeks
so total increase = 7 * 49 = 343
Exponential growth function is given by f(t) = A(1 + k%)^t; where A is the initial value, k is the growth rate and t is the time period.
Therefore, the required function is
f(t) = 120,000(1 + 0.012)^t = 120,000(1.012)^t
After 15 years, the new population is 120,000(1.012)^15 = 120,000 x 1.1959 = 143,512
Answer:
k(3n) = 9n² + 9n
General Formulas and Concepts:
Order of Operations: BPEMDAS
- Substitution and evaluation
Step-by-step explanation:
<u>Step 1: Define</u>
k(n) = n² + 3n
k(3n) is n = 3n
<u>Step 2: Solve</u>
- Substitute: k(3n) = (3n)² + 3(3n)
- Exponents: k(3n) = 9n² + 3(3n)
- Multiply: k(3n) = 9n² + 9n
If you're finding the future value: P=35,000(1-.1/1)^1. this is assuming you want to know the value of it after one year. if you want it to be more years, like two : P=35,000(1-.1/2)^2. When entered into the calculator enter it like so : 35,000(1-(.1/1))^1. when that's done you end up with $31,500. that's the machine's worth. it lost 3,500. 35,000-31500.
