Help differentiate this
Arte-miy333 [17]

Answer:

\displaystyle y' = 20x^3 + 6x^2 + 70x + 9

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Terms/Coefficients
  • Expand by FOIL
  • Functions
  • Function Notation

<u>Calculus</u>

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  

Derivative Rule [Product Rule]:                                                                                \displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em />\displaystyle y = (x^3 + 7x - 1)(5x + 2)<em />

<em />

<u>Step 2: Differentiate</u>

  1. Product Rule:                                                                                                    \displaystyle y' = \frac{d}{dx}[(x^3 + 7x - 1)](5x + 2) + (x^3 + 7x - 1)\frac{d}{dx}[(5x + 2)]
  2. Basic Power Rule [Derivative Property - Addition/Subtraction]:                   \displaystyle y' = (3x^{3 - 1}+ 7x^{1 - 1} - 0)(5x + 2) + (x^3 + 7x - 1)(5x^{1 - 1} + 0)
  3. Simplify:                                                                                                             \displaystyle y' = (3x^2+ 7)(5x + 2) + 5(x^3 + 7x - 1)
  4. Expand:                                                                                                             \displaystyle y' = 15x^3 + 6x^2 + 35x + 14 + 5(x^3 + 7x - 1)
  5. [Distributive Property] Distribute 5:                                                                 \displaystyle y' = 15x^3 + 6x^2 + 35x + 14 + 5x^3 + 35x - 5
  6. Combine like terms:                                                                                         \displaystyle y' = 20x^3 + 6x^2 + 70x + 9

Which operations are the most efficient to use to solve the problem and what is the solution? The Jackson neighborhood has a com
Scorpion4ik [409]
If the area of the Jackson neighborhood garden is 672 yards, and the width of the garden is 21, that means that length of the garden is 32. (672 divided by 21 is 32) Then, since the Nguyen neighborhood garden is 15 yards longer than the length, that means you add 15 to 32, so that your answer is 47.


So first off, is D, and to get there we did the most important part with division and addition, which is A.


Final: D and A.
