Answer: -6250
Step-by-step explanation: The common ratio is -5. By multiplying the terms by this ratio, the sixth term is -6250.
Answer:
x= 10
Step-by-step explanation:
To getyour answer, just divided 3.24 by 12. You will get 0.27. So the answer is each pencil costs 27 cents or 0.27.
To divide these complex numbers you have to multiply by the conjugate of the denominator. That will look like this:
. Multiply straight across the top and straight across the bottom to get
. In the denominator, the 12i and -12i cancel each other out, which is nice. Now, in both the numerator and the denominator we have an i-squared. i-squared is equal to -1, so we will make that substitution in our solution:
. Doing the math on that we have
. We can simplify that as well as write it in standard form:
. Now we will get it into legit standard form, separating the real part of the complex number from the imaginary part.
. That can be reduced to its final answer of
. There you go!
