GhhhgggggghhgghhPlease solve
Jobisdone [24]

Answer:

-i/2

Step-by-step explanation:

Recall that i² = -1.

z² + 1 factors into (z + i)(z - i), and so the original expression reduces as follows:

    z - i               1

--------------- = --------- for z not equal to i

(z + i)(z - i)       z + i

Now attempt to find the limit as z approaches i of the above rational fraction.   The limit is

    1            1                                                                  1

--------- = ------     which, if rationalized, becomes  ------- (-i), or  -i/2

  i + i        2i                                                                2

For which k is it true that the sum of k consecutive integers is always divisible by k?
nevsk [136]

Answer:

Step-by-step explanation:

We have two consecutive even integers:

a and b.

We know that we can write a even integer as:

a = 2*n

where n is an integer.

Then the consecutive integer to a, b, will be:

b = 2*n + 2.

Then the sum of a and b is:

a + b = 2n + 2n + 2 = 4*n + 2 = 2*(2n + 1) = k.

The next two consecutive integers greater than b will be:

c = 2n + 4

d = 2n + 6

then:

c + d = (2n + 4) + (2n + 6) = 4n + 10 = k + 4.

I hope i helped:D

What is the value of the discriminant for the quadratic equation 0 = x + 2 + x2?
Kobotan [32]
The discriminant of a quadratic expression ax^2+bx+c, where a in not 0, is the expression 
                                       D=b^2-4ac.  

Thus, we compare x^2+x+2 to ax^2+bx+c and see that 

a=1, b=1, c=2.

Substituting these values in  D=b^2-4ac, we have:

                               D=(1)^2-4\cdot1\cdot2=1-8=-7.
