Answer:
I don't know the exact answer because I'm 13 but does this help at all? Sorry about before...
Step-by-step explanation:
1. The domain D and range R of the given function are given by: D: (- ∞ , + ∞) and R: (- ∞ , + ∞)
2. In order to find the inverse, we first write the function as an equation as follows. ...
3. Then solve it starting by cubing both sides. ...
4. Simplify and solve for x. ...
5. Change x into y and y into x to obtain the inverse function.
Answer:
Using the formula:
where
A is the total amount
P is the principal
I is the Simple Interest
As per the statement:
Principal(P) = 5300 rupees.
rate of interest(r) = 6.5% = 0.065
Total amount(A) = 6678 rupees.
Then using above formula we have;
Subtract 5300 both sides we get;
or
We have to find the time period.
Using formula of Simple interest:
where r is the rate of interest (in decimal)
here, r = 6.5% = 0.065
Substitute the given values top find t:
⇒
Divide both sides by 344.5 we have;
Therefore, the time period t in years is 4 years
