Analyze the regular polygon and given information below, and determine which mathematical tool should be used in order to find the area of the figure.
#1 _ to find the apothem sin(22.5 °)| sin (67.5 °) | cos (67.5 °) | tan (22.5 °) | tan (67.5 °)
#2 _ to find half the length to the side

tan (22.5 °) | tan (67.5 °) | sin (67.5 °) | cos (67.5 °) | cos (22.5 °)

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.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
