Answer:

f(3) = 1

Step-by-step explanation:

f(x) = x² - 2ˣ

You are solving for f(3). Plug in 3 for x in the equation:

f(3) = (3)² - (2)³

Simplify. First, simplify each number by solving the powers, then subtract:

f(3) = (3 * 3) - (2 * 2 * 2)

f(3) = (9) - (8)

f(3) = 9 - 8

f(3) = 1

f(3) = 1 is your answer.

The property displayed here is the distributive property.

If you have a variable or unknown number inside or outside of parentheses, you can distribute it to each term and add the terms together, and it will remain true.

Example:

4(x + 5)

After distributing, it'll look like this:

4x + 20

Tammy deposited $520 in the bank account that earns simple interest every year after 5 years she had earned $156 and interest if
aleksley [76]

Answer:

6%.

Step-by-step explanation:

We have been given that Tammy deposited $520 in the bank account that earns simple interest every year after 5 years she had earned $156.

To find the interest rate we will use simple interest formula.

I=P*r*T

I= Interest.

P= Principal amount.

r=Annual interest rate (in decimal form).

T= Time in years.

We have been given that I=156, T=5, P=520

Upon substituting our values in above formula we will get,

156=520*r*5

156=2600r

r=\frac{156}{2600}

r=0.06

Let us multiply 0.06 by 100 to convert annual interest rate in percentage.

0.06*100=6 \text{ percent}

Therefore, the annual interest rate was 6%.
