<span>divide $17 by 51 pounds to get the cost per pound. so it would be $0.33 cents per pound
hope this helps!!!</span>
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

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
The discriminant of a quadratic expression
, where a in not 0, is the expression
.
Thus, we compare
to
and see that
a=1, b=1, c=2.
Substituting these values in
, we have:
.
