F(x) = (x^3)-(3x^2)-3x+1 factor please

Mathematics
1 answer:
Anni [7]3 years ago
5 0

Answer:

(x+1)(x²-4x+1)

Step-by-step explanation:

f(x) = x³-3x²-3x+1

     = (x³+1) - 3x (x+1)

     = (x+1)(x²-x+1) - 3x(x+1)

     = (x+1)(x²-x+1-3x)

     = <u>(x+1)(x²-4x+1)</u>

<u />

** (x+1)(x²-4x+1) = (x+1)((x-2)² - 3)

                        = (x+1)((x-2)² - (√3)²)

                        = (x+1)(x-2-√3)(x-2+√3)

A player on a school baseball team reaches first base 3/10 of the time he is at bat.Out of 80 times at bat,about how many times
Cerrena [4.2K]
Set up a proportion: 3/10= x/80. Then if you multiply 10 by 8, you get 80 on both sides, But, If you do it to the top, you also have to do it to the bottom, so the anser is 3 x 8 , or 24.

A farmer has 3/4 acre of land. He will use all the land and plant different vegetables in 1/16 -acre sections. How many sections
kati45 [8]

Answer: 12 sections of 1/16 acre

Step-by-step explanation:

We want to find how many sections of 1/16 acre we can have in a total area of 3/4 acre.

This is equal to the quotient between 3/4 and 1/16

Remember that if we have two rational numbers (a/b) and (c/d) the quotient can be writen as:

(a/b)/(c/d) = (a/b)*(d/c) = (a*d)/(b*c)

The quotient we want to solve is:

(3/4)/(1/16) = (3/4)*(16/1) = (3*16)/4 = 12

Then you can have 12 sections of 1/16 acre

Round each amount to the nearest hundred to find an estimate of 9635-4891
Snezhnost [94]

Answer:

4700

Step-by-step explanation:

Rounding to 100: Look at the tenth value. If this value is greater than or equal to 5, round up. If this value is less than 5, round down.

9635 = 9600

4891 = 4900

9600 - 4900 = 4700

You can check if it's accurate by comparing it to the original.

9635 - 4700 = 4744

Taya2010 [7]

Answer:

The probability that the person will not  be a senior

P(E⁻) = 1 - P(E)

       =  1- \frac{5}{9} = \frac{4}{9}

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given A high school club has 10 members who are seniors and 8 members who  are juniors

n(S) = 10 + 8 = 18

If a member is randomly selected to be the club president

Let 'E' be the event that the person will  be a senior

The probability that the person will  be a senior

      P(E) = \frac{n(E)}{n(S)}

     P(E) = \frac{n(E)}{n(S)} = \frac{10}{18} = \frac{5}{9}

The probability that the person will not  be a senior

P(E⁻) = 1 - P(E)

       =  1- \frac{5}{9} = \frac{4}{9}
