An initial investment of $60.00 increases in value by 15% each year. which of the following statements are true? select all that apply. round your answers to the nearest dollar.

Given:initial investment = $60.increase in value by 15% each year
The function that best represents the above problem is: f(x) = 60 * (1.15)^x
f(4) = 60 * (1.15)⁴ = 60 * 1.75 = 105.00f(6) = 60 * (1.15)⁶ = 60 * 2.31 = 138.60f(7.86) = 60 * (1.15)⁷.⁸⁶ = 60 * 3 = 180After 7.86 years the value of the investment will be 3 times the initial valuef(8) = 60 * (1.15)⁸ = 60 * 3.06 = 183.60 After 8 years the value of the investment will be $184.00 

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
