geniusboy [140]

Answer:

\displaystyle \frac{dy}{dx} = 2x

General Formulas and Concepts:

<u>Calculus</u>

Differentiation

  • Derivatives
  • Derivative Notation

Derivative Property [Multiplied Constant]:                                                           \displaystyle \frac{d}{dx} [cf(x)] = c \cdot f'(x)

Derivative Property [Addition/Subtraction]:                                                         \displaystyle \frac{d}{dx}[f(x) + g(x)] = \frac{d}{dx}[f(x)] + \frac{d}{dx}[g(x)]  

Basic Power Rule:

  1. f(x) = cxⁿ
  2. f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

\displaystyle y = x^2 - 3

<u>Step 2: Differentiate</u>

  1. Derivative Property [Addition/Subtraction]:                                                 \displaystyle y' = \frac{d}{dx}[x^2] - \frac{d}{dx}[3]
  2. Basic Power Rule:                                                                                         \displaystyle y' = 2x

Read the power and then check all that apply.
erastovalidia [21]
Check all the ones listed below:

1. The base is 3

(you are multiplying 3 four times or 3 to the power of 4 )

2. The exponent is 4

( 3 is the number you are multiplying and the exponent or 4 tells you how many times you multiply the base which is 3)

3. The exponent tells you to multiply the 3 together 4 times

( 3x3x3x3 is multiplying the number 3, 4 times)

Delia relative long jump length was recorded as 0. What does this mean
Deffense [45]

<span>When we say about an object relative to something, this only means that we are comparing an object’s characteristic to that of our reference. So in this case, I think we are referencing Delia’s jump to someone else. Say our reference has a long jump length of 5 meters, since Delia’s relative long jump length is 0, this means that relative to the reference there is no difference. Therefore, Delia’s jump length is also 5 meters.</span>

The commission on the sale of a property is 5.5% of the value. What is the commission on the sale of a property that has the sam
Kruka [31]

Answer: $1179.75

Step-by-step explanation:

Percentage of commission = 5.5%

Value of property = $21,450

Commission = Percentage commission × Value of property

= 5.5% × $21,450

= 5.5/100 × $21,450

= 0.055 × $21,450

= $1179.75

The commission is $1179.75
