Let's say that h(x) = x+3. To find the inverse switch h(x) and x and call h(x) by its inverse name
. so f(x) = x - 3.
so h(f(x)) = (x - 3) + 3 = x what we did is plug f(x) in for x which is the inverse of h(x). The answer is h(f(x)) =x.
Answer:
There are 406 students in the school
Step-by-step explanation:
Let the number of students in the school be x
The total ratio is 11 + 3 = 14
The ratio that buys lunch is represented by 3
So, we have it that;
3/14 * x = 87
3x = (14 * 87)
x = (14 * 87)/3
x = 406
$394.51 is future value of money after 2 years.
What future value means?
- A current asset's future value (FV), which is based on an estimated rate of growth, is its value at a later time.
- Investors and financial planners use the future value to project how much an investment made now will be worth in the future.
The method that results in more money after 2 years is Peggy's investment.
Which method results in more money in 2 years?
The formula for calculating the future value of an investment:
FV = P (1 + r)^nm
FV = Future value
P = Present value
R = interest rate
m = number of compounding
N = number of years
Future value of Larry's investment: $350 x [1 + (0.04/4)]^(4 x 2) = $379
Future value of Peggy's investment: $350 x [1 + (0.06/12)]^(12 x 2) = $394.51
