4. A man is standing atop of a tower, 218 ft above the ground. A spot has been marked on the
ground below him with a big “X.” When he looks down with an angle of descent of 12° he can
see the “X”. How far away from the base of the tower is the “X”? Draw a picture and show all
work.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

360/29

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
