Answer:
1) x= 3i, x= - 3i
2) x= +i, x = - i
Step-by-step explanation:
1) x^2+9=0
(x+3i)(x-3i)=0
x= 3i, x=-3i
2) x^2-4=-11
x^2=-7
x= ±i
x= +i, x = - i
hope this helps!! :))
The formula that calculates the compound rate from the given values is
The compound interest formula is:
Where:
- P represents the principal amount
- r represents the compound interest rate
- n represents the number of times the interest is compounded
- t represents the time in years
- I represents the interest
We start by adding P to both sides
Divide through by P
Take the nt-th root of both sides
Subtract 1 from both sides
Multiply through by n
In this case, t = 10
So, we have:
Hence, the formula that calculates the compound rate is
