We need to find the interest rate in order to solve this problem:
.12/12 = (.01)
The number of years is unknown. T represents time in the following formula:
1000 (initial investment)
2000 (balance after t years from investment)
=$2000
In order to isolate the exponential term, both sides must be divided by 1000.
=2
By using natural logarithm:
By dividing both sides of the equation by 
Hello from MrBillDoesMath!
Answer:
See Discussion below
Discussion:
Let a/b and c/d be rational numbers we wish to multiply. Then
(a/b) * (c/d) = (a*c)/(b*d)
The numerator (a*c) is the product of two integers ( a and c) and the denominator (b*d) is also ( b and d). In that way multiplying rational numbers is like multiplying integers.
Thank you,

Answer:
Step-by-step explanation:
in complementary angle sum of two angle is always 90 degree.so,
let another be x
x+28.1=90
x=90-28.1
x=61.9
therefore another angle is 61.9 degree.
