Answer:

- 13

Step-by-step explanation:

Substitute x = - 1 into f(x) to obtain the remainder on dividing by (x + 1)

f(- 1) = - 2(- 1)³ - 4(- 1)² + 3(- 1) - 8

       = 2 - 4 - 3 - 8 = - 13

Thus the remainder on dividing f(x) by (x + 1) is - 13

Hello

- 13

Explanation step by step:

x = - 1

f (x) = remainder to be divided by (x + 1)

f (- 1) = - 2 (- 1) ³ - 4 (- 1) ² + 3 (- 1) - 8

= 2 - 4 - 3 - 8 = - 13

<u> The rest of the division of f (x) / (x + 1) = -13</u>

x^{-m}= \frac{1}{x^m}

so

10^{-4}= \frac{1}{10^4}= \frac{1}{10000}=0.0001

The sum of three numbers is 18. If every number is a prime number, what are the three numbers?
sleet_krkn [62]
The three numbers are 2, 5, and 11.

The sum of 3 numbers is 18.        2 + 5 + 11 = 18

Since the problem states that every number is a prime number, then the number must be a natural number greater than 1 that has no positive divisors other than 1 and itself.

2 / 1 = 2  OR  2 / 2 = 1  These numbers are prime numbers because their divisors
5 / 1 = 5  OR  5 / 5 = 1            are 1 and itself.
11/1 = 11 OR 11/11 = 1
