Complete the square and put this function in vertex form: f(x)=x^2+20x+96

Mathematics
1 answer:
krok68 [10]3 years ago
6 0

Answer:

f(x) = (x+10)^2 - 4

Step-by-step explanation:

vertex form is y = a(x-h)^2+k

to complete the square, we want to add a number on both sides so x^2+20x+whatver the number is, is the square of something

to find that number take 20, divide by 2, and then square it to get 100.

so, you would get f(x)+100 = x^2+20x+100+96

subtract 96 on both sides: x^2+20x+100 = f(x) + 4

factor: f(x) = (x+10)^2 - 4

____ [38]
The correct answer is letter C.

The reason is because there are 12 cake donuts out of the 36 total.  This is a simple ratio of 1 to 3.  This means one out of every 3 people would get a cake donut.  If there are 12 people, this is 4 groups of 3, so one person from each group of 3 is 4 people.
