For a moving object, the force acting on the object varies directly with the objects acceleration. when a force of 40 n acts on a certain object, the acceleration of the object is 4m/s^2. if the force is changed to a 60 n, what will be the acceleration of the object?

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.

i belive those are the ones that are under 90 degreese.

1/3 + 1/5 = 8/15.
