Answer:
y =x
Step-by-step explanation:
the cordinate of y = x is the same line going form top to bottom
For this case we have a direct variation of the form:
Where "k" is the constant of proportionality. To find it, we use the following data:
Substituting:
Clearing the value of k:
Thus, the direct variation is given by:
For
we have:
Answer:
The value of the direct variation for is: 
Present value, PV = $500
Future value, FV = 2*PV = 2*500 = $1,000
Rate, r = 4% = 0.04
Compounding times in a year, n = 4 (compounded quarterly)
Time, t = ??
The future value expression is stated as:
FV = PV (1+r/n)^nt
Substituting;
1000 = 500 (1+0.04/4)^4t
2 = (1.01)^4t
ln 2 = 4t ln 1.01
0.6931 = 4t* 0.00995
0.6931 = 0.0398t
t = 17.414 years
Time required for the amount to double is 17.41 years.
M<2 = 60
m<1 = 180 - 60
m<1 = 120
