Answer:
Number of year = 17 year 4 month (Approx.)
Step-by-step explanation:
Given:
Current amount = $500
Future amount = 2 x 500 = $1,000
Rate of interest = 4%
Find:
Number of year
Computation:
Rate [Monthly] = 4% / 12 = 0.00333
Total time = 12 x n = 12n
A = P[1+r]¹²ⁿ
1000 = 500[1+0.003333]¹²ⁿ
2 = [1+0.003333]¹²ⁿ
2 = [1.003333]¹²ⁿ
Number of year = 17.358
Number of year = 17 year 4 month (Approx.)
8.5+8.6=73.1÷2=36.55
formula for midpont a+b divide 2
Answer:
B. y = [x] + 7
Step-by-step explanation:
If you are going left on the x-axis your sign would be positive
We can divide 15 by 4. This gives us 3.75. This means that each pizza costs $3.75. I can now multiply 3.75 by 5.
3.75(5) = 18.75
5 pizzas cost $18.75.
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
