  • 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

HELP WANTED, APPRECIATED, AND NEEDED ASAP

Let's assume

x is number of hours worked

y is amount paid

Since, this is linear relationship

We can select any two points

(2,36.50) and (4,73)

so, we can also write as

x1=2 , y1 =36.50

x2=4 , y2=73

Firstly, we can find slope

m=\frac{y_2-y_1}{x_2-x_1}

we can plug values

m=\frac{73-36.50}{4-2}

m=18.25

now, we can use point slope form of line

y-y_1=m(x-x_1)

we can plug values

y-36.50=18.25(x-2)

now, we can solve  for y

y=18.25x

or

y=18.3x..............Answer
