bridget recieved 1400 from her grandfather as a birthday gift she decided to put the money in an account to save for college the
Simora [160]

Answer:

The amount received after 5 years is 1827.39

Step-by-step explanation:

The amount received by Bridget from his grandfather as the birthday gift = 1400 .

Since he wants to deposit it and save for college, he earns interest rate = 5.4%

He deposited this money for the years = 5 years.

Here, the Present value (PV) is = 1400

Interest rate ( r ) = 5.4% or 0.054

Since the interest rate is compounded semi annually, So, n = 10

Now if we calculate the future value of 1400 with interest rate 5.4 percent:

\text{The amount received after 5 years} = PV(1 + \frac{r}{2} )^{n} \\

= 1400(1 + \frac{0.054}{2})^{10} \\

= 1827.39

Therefore, 1827.39 will be the total money in his account after five years.

Choose the four expressions that are equivalent to 3^-4 ?
Ivan

3^(-4) means "one over 3^4"

    1/(3^4)

That's equal to

    1/81

and

    (1/3)^4

This is also equal to 3^2/3^6.  

So four of those are correct.
