A school has a parking lot that is 150.23 feet by 135.12 feet. What is the perimeter of the parking lot?
elena-14-01-66 [18.8K]

Answer: 570.70 ft

Step-by-step explanation:

The perimeter is the distance around the entire parking lot.

The measurement of 150.23 ft by 135.12 ft is half of the distance of the lot because it represents just two sides yet there are 4 sides.

The other two sides have the same measurement as this is a rectangle.

The perimeter of the parking lot is:

= (150.23 * 2) + (135.12 * 2)

= 570.70 ft

Find the derivative using the limit process of f (x) = - 10x
zubka84 [21]

Answer:

\frac{d}{dx} f(x) =-10

General Formulas and Concepts:

<u>Calculus</u>

  • Derivative Notation
  • Definition of a Derivative: \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = -10x

<u>Step 2: Find Derivative</u>

  1. Substitute:                         \frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10(x + h)-(-10x)}{h}
  2. Distribute -10:                    \frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10x -10h-(-10x)}{h}
  3. Distribute -1:                      \frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10x -10h+10x}{h}
  4. Combine like terms:         \frac{d}{dx} f(x)=  \lim_{h \to 0} \frac{-10h}{h}
  5. Divide:                               \frac{d}{dx} f(x)=  \lim_{h \to 0} -10
  6. Evaluate:                           \frac{d}{dx} f(x)=-10
