Answer:
![t=1.4\ years](https://tex.z-dn.net/?f=t%3D1.4%5C%20years)
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
solve for t
![t=1.4\ years](https://tex.z-dn.net/?f=t%3D1.4%5C%20years)
Answer:
2.
Domain: all real values of x
Range: f(x)》-4
3.
Domain: all real values except x = 0
Range: All real values except f(x) = 0
Step-by-step explanation:
2.
Domain: all real values of x
Range: f(x)》-4
Because this is a concave up quadratic with a minimum turning point at (0,-4)
3.
Domain: all real values except x = 0
Range: All real values except f(x) = 0
Since x is in the denominator, it can't be 0
For f(x) = 0, x has to be infinity
It is unknown since there is a 50-50 chance it could be heads or tails
