Answer:
, where
is the <u>time (in years) from investment</u>
Or
, where
is the <u>age of James</u>
Step-by-step explanation:
exponential model:
, where
is the time (in years) from investment
when t = 0, y = 750
![\implies 750=ab^0](https://tex.z-dn.net/?f=%5Cimplies%20750%3Dab%5E0)
As ![b^0=1](https://tex.z-dn.net/?f=b%5E0%3D1)
![\implies 750=a](https://tex.z-dn.net/?f=%5Cimplies%20750%3Da)
Therefore, ![y=750b^t](https://tex.z-dn.net/?f=y%3D750b%5Et)
If the savings increase by 5% each year, then b = 105%.
105% = 105/100 = 1.05
Therefore, b = 1.05
So final model:
, where
is the time (in years) from investment
Or, we can write this as
, where
is the age of James

Answer:
61
Step-by-step explanation:
PS is a midsegment of the triangle, so is half the length of the parallel base segment.
2PS = QR
2(x -16) = x +29 . . . . . substitute given expressions
2x -32 = x +29 . . . . . eliminate parentheses
x = 61 . . . . . . . . . . . . add 32-x
