Step-by-step explanation:
The given function is 
This function is of the form;
where 
is the amplitude.
When we compare to , we have
, therefore the amplitude of the given cosine function is 
The period is given by;

If an item has been discounted 30%, then it is currently worth 70% of the original price. This tells us that $49 is 70% of the original price. Therefore, you need to divide $49 by 70% to get your answer (you have to work backwards; remember that you would have multiplied the original number by 0.7 to get 49):
49÷(70/100)= $70
Therefore, the price of the original product was $70
Answer:
current market price of the bond is $958.73
Step-by-step explanation:
given data
coupon rate = 5.74 percent
yield to maturity = 6.1 percent
bond matures = 20 years
future value = $1,000
solution
we get here PMT that is
PMT = 1,000 × 5.74% ÷ 2 ...............1
PMT = $28.70
and Number of Periods is
NPER = 20 years × 2 = 40 semi-annual periods
and here Rate of interest will be = 6.1% ÷ 2 = 3.05%
and we use here formula that is
= -PV(Rate;NPER;PMT;FV;type)
so we get
current market price of the bond is $958.73
I'm pretty sure this doesn't belong in mathematics but this belongs to science. Anyways.. an independent variable is the only variable that is being changed. The dependent variable is what you find out- in other words it is the outcome.
