A survey asked 24,000 national park visitors to choose their favorite type of landscape. The results are shown in the following table. (a) Find the percentage for each type of landscape. Type of landscape Number of park visitors Percentage x 5 ? Beach 6720 Mountain 10,800 [% % 1% 1% Forest 5040 Plains 1440 (b) Construct a percent bar graph for the data. 4% 88% 4% 4% 0% 4% 92% 96% 100% Beach Mountain Forest Plains x 6

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

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.
