A number, X, rounded to 1 decimal place is 3,7<br> Write down the error interval for x,
sp2606 [1]

Answer:

The error interval for x is:

                 [3.65,3.74]

Step-by-step explanation:

The number after rounding off is obtained as:

                         3.7

We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:

  3.65     3.66    3.67    3.68    3.69    3.70    3.71   3.72    3.73    3.74

( Because if we have to round off a number present in decimals to n place then if  there is a  number greater than or equal to 5 at n+1 place then it will result to the one higher digit  at nth place on rounding off and won't change the digit if it less than 5 )

        Hence, the error interval is:

            [3.65,3.74]

Given that x-1 and x+2 are factors of f(x)=x³+px+q where p and q are integers, find p and q. Hence, find the remainder when x³+p
alexandr1967 [171]

Answer:

  • p = -3
  • q = 2
  • remainder = 4

Step-by-step explanation:

We want to find the constants 'a', 'p', and 'q' such that ...

  (x -a)(x -1)(x +2) ≡ x³ +px +q

  (x -a)(x² +x -2) ≡ x³ +px +q

  x³ +x² -2x -ax² -ax +2a ≡ x³ +px +q

This gives rise to three equations:

  1 -a = 0 . . . . coefficient of x²

  -2 -a = p . . . coefficient of x

  2a = q . . . . . constant

The first of these tells us a=1. Then, p=-3 and q=2.

The values of p and q are -3 and 2, respectively.

__

The remainder from division by (x+1) is the value of the cubic for x=-1. That value is ...

  (-1)³ -3(-1) +2 = -1 +3 +2 = 4

The remainder from division by (x+1) is 4.
