Answer:
r = -
Step-by-step explanation:
Given that r varies inversely as t , then the equation relating them is
r = ← k is the constant of variation
To find k use the condition t = - 6 when r = - 2, then
- 2 = ( multiply both sides by - 6 )
12 = k, thus
r = ← equation of variation
when t = - 7, then
r = = -
Answer:
620.63
Step-by-step explanation:
use the formula given
r= interest rate
n= numer of times it's compounding in a year
t= time
p= principle amount
