You place $4,000.00 in a bank account with an interest rate of 5.25% apr and another $2,000.00 in an account with an interest rate of 6.00% apr. after 6 months, what is the difference in interest that the accounts earn?

$45.00

$33.09

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.

it’s the first one your welcome

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
