Answer:the last one
Step-by-step explanation:
Answer:
-14 - 11i
Step-by-step explanation:
You may be learning about the imaginary number, i. Even though i is actually the squareroot of -1, when you are doing algebra with it, it acts just like a variable does. The special thing to remember about i is that i^2 is -1. But we don't even need that right now for this problem.
(-14 + 3i) - (14i)
= -14 + 3i - 14i
Combine the i's
= -14 - 11i
That's it. The -14 is the a, and the -11 is the b in a+bi.
If necessary to fill in a computer answer that is already formatted with a plus, like:
_ + _i
then use -14 for a and -11 for b.
//I'll use the discriminant rule for this.
b^2 - 4ac = 0 when one real root
Therefore, k^2 - 4*3*4= 0
k^2 = 48
k= +-4√3
Answer:
numbers less than 5 are 1,2,3,4 and equal to 5 is 5.
probability of less than 5 is 4/16
while equal to 5 is 1/16
or means additions; so its 4/16 +1/16=5/16
