Leslie is making a cardboard box that has a volume of 2x3 + 3x2 − 11x − 6 cubic feet. the base has an area of x2 + x − 6 square feet. what will the height of the box be? (hint: volume = base area · height)

we know that

The volume of the box is equal to

V=area of the base*height

solve for the height

height=Volume/(area of the base)

using a graph tool-----> find the roots

see the attached figures

so

substitute

height=Volume/(area of the base)

therefore

the answer is

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
