A mortgage, hope this helped :)
Answer:
A. 0.186524036
Step-by-step explanation:
Cosine 79° 15'
But, 1° = 60'
Thus; 15' = 15/60 = 0.25°
Therefore;
cos 79° 15' = cos 79.25°
Cos 79.25° = 0.186524036
= 0.186524036
Use the formula i=prt, where i is the interest earned, p is the principal, r is the rate (as a decimal fraction) and t is the elapsed time, in years.
Here i = $72 = $1200 r (9/12) (9 months is 9/12, or 3/4, of 1 year)
Reducing,
$72 = $900r
Solving for r, r=0.08, or 8 percent per year.
It is beans and Obama 3+8 and u have to simplify for negative
