The formula for compound interest is : A = P(1+r/n)^nt
A = 4000 (1+0.021/4)^4x4
A = 4000 (1.021)^16
A = 5,577.91
Sergio's total interest would be : 5,577.91 - 4,000 = $ 1,577.91
hope this helps
Answer:
Step-by-step explanation:
First of all, I have a strong feeling that that is supposed to be
so I'm going to go with that. We can solve for y by rewriting that in exponential form. Exponential form and log form are inverses of each other. If the log form of an equation is
, the exponential form of it is
. We will apply that here to solve for y:
![2^y=32](https://tex.z-dn.net/?f=2%5Ey%3D32)
which is asking us, "2 to the power of what equals 32?". We can use our calculator to raise 2 to consecutive powers til we reach the one that gives us a 32, or we could solve it by writing the 32 in terms of a 2:
![2^y=2^5](https://tex.z-dn.net/?f=2%5Ey%3D2%5E5)
Since both bases are the same, 2, then the exponents are equal to one another. y = 5. This is an important rule to remember while solving either log or exponential equations.
