Using the Fundamental Counting Theorem, we have that:

4. 1,757,600 different license plates can be there.

5. 676,000,000 different driver's license numbers can be formed.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

For the letters there are 26 outcomes and for the digits there are 10 outcomes, hence the parameters for item 4 are given as follows:

n_1 = n_2 = 26, n_3 = n_4 = 10, n_5 = 26

Hence the number of license plates is given by:

N = 26 x 26 x 10 x 10 x 26 = 1,757,600.

For item 5, the parameters are:

n_1 = n_2 = 26, n_3 = n_4 = n_5 = n_6 = n_7 = n_8 = 10

Hence the number of license numbers is:

26 x 26 x 10 x 10 x 10 x 10 x 10 x 10 = 676,000,000

What’s the derivative of x^2 - 3
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
