  • The derivative of a constant is equal to 0
  • Derivative Property: \frac{d}{dx} [cf(x)] = c \cdot f'(x)
  • Trig Derivative: \frac{d}{dx} [cos(x)] = -sin(x)

Step-by-step explanation:

<u>Step 1: Define</u>

g(x) = 8 - 10cos(x)

x = 0

<u>Step 2: Differentiate</u>

  1. Differentiate [Trig]:                    g'(x) = 0 - 10[-sin(x)]
  2. Simplify Derivative:                   g'(x) = 10sin(x)

<u>Step 3: Evaluate</u>

  1. Substitute in <em>x</em>:                    g'(0) = 10sin(0)
  2. Evaluate Trig:                      g'(0) = 10(0)
  3. Multiply:                               g'(0) = 0

Olin [163]

Answer:  226.5 ft²

<u>Step-by-step explanation:</u>

I divided the image into 3 rectangles and 1 triangle.

top rectangle: length = 9, height = 4          -->      A = 9 x 4 =   36

middle rectangle: length = 15, height = 7   -->      A = 15 x 7 = 105

bottom rectangle: length = 18, height = 4  -->      A = 18 x 4 =   72

triangle: base = 9, height = 3                      -->  A = (9 x 3)/2 = <u>   13.5 </u>

<u>Total                                                         </u>                               =  226.5
