$\frac{30w^3-6w}{6w} = \frac{6w(5w^2-1)}{6w} =5w^2-1$

First simplify the numerator by dividing by the greatest common factor 3w^3-6w= 6w(5w^2-1) _________________________ 6w the 6w can be divided in the numerator and denominator and cancel out= 5w^2-1 hope this helps

At what points on the graph of f(x)=2x^3-6x^2-27x is the slope of the tangent line -9?

Dmitriy789 [7]

Answer:

(-1, 19) and (3, -81)

Step-by-step explanation:

f(x) = 2x³ − 6x² − 27x

f'(x) = 6x² − 12x − 27

-9 = 6x² − 12x − 27

0 = 6x² − 12x − 18

0 = x² − 2x − 3

0 = (x + 1) (x − 3)

x = -1 or 3

f(-1) = 19

f(3) = -81

The points are (-1, 19) and (3, -81).

Determine the area of the composite figure to the nearest whole number. A) 132 ft2 Eliminate B) 176 ft2 C) 184 ft2 D) 216 ft2

Sergeeva-Olga [200]

Answer:

B) 176 ft²

Step-by-step explanation:

The picture below is the attachment for the complete question. The figure has 3 halves of a circle and a square . The area of the figure is the sum of their area.

Area of a square

area = L²

where

L = length

L = 9 ft

area = 9²

area = 81 ft²

Area of the 3 semi circles

area of a single semi circle = πr²/2

For 3 semi circle = πr²/2 + πr²/2 + πr²/2 or 3 (πr²/2)

r = 9/2 = 4.5

area of a single semi circle = (3.14 × 4.5²)/2

area of a single semi circle = (3.14 × 20.25 ) /2

area of a single semi circle = 63.585 /2

area of a single semi circle = 31.7925

Area for 3 semi circles = 31.7925 × 3 = 95.3775 ft²

Area of the composite figure = 95.3775 ft² + 81 ft² = 176.3775 ft

Area of the composite figure ≈ 176 ft²
