The answer of f(-2) is 42
Answer:
Irrational
Step-by-step explanation:
Any number that can be written as a fraction or a ratio is a rational number. The product of any two rational numbers is therefore a rational number, because it too may be expressed as a fraction. For example, 5/7 and 13/120 are both rational numbers, and their product, 65/840, is also a rational number.
An irrational number is a number that is NOT rational. It cannot be expressed as a fraction with integer values in the numerator and denominator. When an irrational number is expressed in decimal form, it goes on forever without repeating.

The nth term of the sequence whose integers are between 1 -7 such that there is the permission of repetition but no two consecutive digits must be even is 1.254 × 10¹¹
<h3>What are consecutive numbers?</h3>
Consecutive numbers are those numbers that succeed each other in increasing order from least to greatest. The numbers that are given:
- 1, 2, 3, 4, 5, 6, or 7 are all consecutive.
Now, suppose a (n) denotes the number of n-digit positive integers as stated in the question, thereby using:
- 1, 2, 3, 4, 5, 6, or 7 with the permission of repetition; no two consecutive digits are even.
Then, the number of n can be computed as n!
= (7!) × (6!) × (5!) × (4!) × (3!) × (2!) × (1!)
= 1.254 × 10¹¹

The original price is $199.94
Given:
Discounted price = 159.95
Discount rate = 20%
If the discount rate is 20%, then the price is equivalent to 80%.
To get the original price, simply divide the discount price by its corresponding percentage.
Original price = 159.95 ÷ 80% = 199.94
To check
199.94 * 20% = 39.99 * value of the discount
199.94 - 39.99 = 159.95 *discounted price
