Answer:the available amount after 28 years is $128000
Step-by-step explanation:
The initial value of the investment is
$8000. The value doubles in every 7 years.
The function that models the growth of this investment is f(x)=8000•2^x
where
x represents the number of doubling periods.
To determine the amount of money that will be available for withdrawal after 28 years, we would determine the number of doubling periods first. Therefore,
x = 28/7 = 4
Therefore, the available amount after 28 years would be
f(x)=8000•2^4 = 8000×16 = $128000

Answer:
42° and 48°
Step-by-step explanation:
Complementary angles sum to 90°, hence
x + 10 + x + 4 = 90
2x + 14 = 90 ( subtract 14 from both sides )
2x = 76 ( divide both sides by 2 )
x = 38
x + 10 = 38 + 10 = 48° and x + 4 = 38 + 4 = 42°
