The Bisection Method for Approximating Real Zeros • Find the zeros of the polynomial found in task 1.
Find to the nearest tenth the third zero using the Bisection Method for Approximating Real Zeros. Since f (3) = -14 and f (4) = 15, there is at least one real zero between 3 and 4. The midpoint of this interval is 3.5. Since f (3.5) = -3.5, the zero is between 3.5 and 4. The midpoint of this interval is 3.7. Since f (3.7) is about 2.856, the zero is between 3.5 and 3.7. The midpoint of this interval is 3.6. Since f (3.6) is about -0.488. The zero is between 3.6 and 3.7. The midpoint of this interval is 3.65. Since f (3.65) is about 1.14, the zero is between 3.6 and 3.65. The midpoint of this interval is 3.625. Since f (3.61) is about -0.168, the zero is between 3.6 and 3.625. Therefore, the zero is 3.6 to the nearest tenth.
Real World Construction You are planning a rectangular garden. Its length is twice its width. You want a walkway w feet wide around the garden. Let x be the width of the garden.
a. Choose any value for the width of the walkway w that is less than 6 ft. W = 5 length= 10 • Write an expression for the area of the garden and walk. • Area=2x+10x+10 • =2x2+20x+10x+100 • =2x2+30x+36
c. Write an expression for the area of the walkway only. • 2(2x+105)+2(5x) 2((10x + 50)) + 10 x 20x+100+10x 30x+100
