Ineed math . look at the attachment. no multiple choice.

there are 4 quarters per year

 if annual rate = 8%

 quarterly rate would be 8%/4 = 2%

 so the (1+r) beomes (1+0.02) = 1.02

1e+27

step-by-step explanation:

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.
