Answer:
Vertex form: 
The vertex is 
Step-by-step explanation:
For a general quadratic function the form is:
For the function
The values of the coefficients for the function are the following: 
, 
, 
Take the value of b and divide it by 2. Then, the result obtained squares it.
Add and subtract 
Write the expression of the form
The vertex is (h, k)
The vertex is:
Answer: 20.7
Step-by-step explanation:
Step 1. Ok, to round to the nearest 10th means to round to the nearest 10th place on the decimal side of the of the number.
Step 2. The 10th place in this decimal 10.73 is where the 7 is.
Step 3. If the 100th place is less than 5 you round down. Since, the hundredth place in this decimal is where the 3 is you are going to round down.
The answer is 20.7. Hope this helps!
Tip: use Slader (the app or the website) it gives you the anwsers and it tells you how to do it as well.

Answer:
i ^ (2n) = (i^2)^n = (-1)^n = -1 if n is odd and = 1 if n is even
i ^ (2n+1) = i^(2n)* i = -1 * i = -i if n is odd and = 1*i = i if n is even
Not sure if this answers your question but hopefully pushes you n the right direction.
Thank you,

Answer:
Six friends spend $84 on dinner and split the bill evenly. Write a multiplication equation to solve how much each person paid. f=variable each person paid.
6f/6=84/6 f=14
Step-by-step explanation:
6f=84
6/6f=84/6 cross out the sixes. Then, f=84/6. So, 84 divided by 6= 14. f=14. Each person paid $14.
