Jaryssa invested $10,000 in a construction fund paying 12% return every year. Jaryssa considered 2 options for her investment: 1) collecting the return every year.
2) re-invest all the returns in the same fund.
John claimed that after 7 years, Jaryssa will end up with the same amount of money from this investment, while Lary strongly disagreed.
a) Calculate how much money would Jarrysa receive from this investment. (Net of her initial $10,000)
b) Write a function to represent the value of Jarrysa’s investment under each option
c) Graph the 2 functions in part b
d) When would the 2 options give her the same return?
e) How long would it take for Jaryssa to have 20,000 under each plan

Step-by-step explanation:

20-year period of time $600 + $80 = $680 Step 3: Divide the total dollar amount of return (Step 2) by the original investment.

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
