Answer:
Simple Interest: A = P(1+rt)
Step-by-step explanation:
P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Ex1: If $1000 is invested now with a simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160
To find slope, use the equation:
(y₂ - y₁)/(x₂ - x₁) = slope
Let:
(8,8) = (x₂, y₂)
(5,5) = (x₁, y₁)
Plug numbers into corresponding areas.
(8 - 5)/(8-5) = 3/3
3/3 = 1
The slope of the line is 1, or 1/1 (rise 1, run 1)

Answer:
Officers can be chosen in 5,814 different ways.
Step-by-step explanation:
Given that the bowling team at Lincoln High School must choose a president, vice president, and secretary, to determine, if the team has 19 members, in how many ways could the officers be chosen, the following calculation must be performed:
19 x 18 x 17 = X
342 x 17 = X
5.814 = X
Therefore, officers can be chosen in 5,814 different ways.
