Bao was given $\$1,\! 000$ for his birthday. he decided to invest the money in a bank account that earns $10\%$ interest, compounded annually. in dollars, how much total interest will bao have earned 3 years later?

 total interest

Step-by-step explanation:

The formula to find the compound interest is given by :-

, where P is the principal amount, r is the rate of interest , n is the time period.

Given : P=$1000,   r=10%=0.01        n=3 years

Then, the interest in 3 years will be :-

Hence, Bao will have earned  total interest of $30.30.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
