Answer:
1) Mining
2) Ranching
3) Commercial Farming
Explanation:
The miners who comes mostly from California and other areas fulfilled the demand for gold and silver in the East. They also contributed in extracting other minerals i.e. copper, zinc, iron ore, lead, and quartz, which were great for the industrial use.
The sheep and cattle ranchers played an important role too i.e. that they produced wool, meat, and leather to satisfy the demands of eastern manufacturers and the consumers.
The farmers contributed by making farming commercial. They sold their crops in home town and internationally which helped the economy to improve.

Answer:
The correct answer is:
$73,009 (a.)
Explanation:
Future value is the accumulated compounded interest on a certain amount (present value) invested over a specified period of time.
To calculate the future value or present value, the nominal annual interest, the duration of investment and the present value or future value respectively must be known. The relationship is shown mathematically as:

or 
where FV = Future value
PV = present value
i = nominal interest rate in percentage
n = number of compounding period
note: nominal interest rate is interest rate before inflation adjustments or interest rate before the effect of compounding
In this question, we are to determine the present value (PV), because the future value after 25 years is set as $500,000.
∴ 

= $73,009 (to the nearest dollars)
The owner of a corporation would be called the president (or sometimes its the CEO if it's a smaller company). The bondholders are the people who own bonds that a company gives them. So the answer would be false.
