Answer:
119
Step-by-step explanation:
m - 1/m = 3
(
An=a1+d(n-1)
a13=1.9
1.9=a1+3.7(13-1)
1.9=a1+3.7(12)
1.9=a1+44.4
minus 44.4 both sides
-42.5=a1
an=-42.5+3.7(n-1)
S_24, so sum all theway up to a24
S_n=(n(a1+an))/2
a1=-42.5
a24=-42.5+3.7(24-1)=42.6
S_n=(24(-42.5+42.6))/2
S_n=(24(0.1))/2
S_n=(2.4)/2
S_n=1.2
D
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
