Answer:

y=(x-8)^{2}+2

Step-by-step explanation:

When calculating the quadratic function in vertex form, you just have to create a quadratic binomial with the values in the function, and then you add or withdraw from the equation what you need to complete the quadratic binomial.

y = x^{2}  - 16x + 66

So you now know that to create a quadratic binomial, you have to divide the B by 2, and then square it, remember that "B" is the numeric value on the second term of the equation, in this case is -16, so divided by 2 it would be -8 and squared it would be 64.

y = x^{2}  - 16x + 66\\y=x^{2}  - 16x + 64 +2\\y=(x-8)^{2}+2

So now you know that the quadratic function in vertex form is:

y=(x-8)^{2}+2

Hello : 
<span>y = x2 - 16x + 66
y=(x²-16x+64)-64+66
y = (x-8)²+2  .....(</span><span>vertex form)</span>

Since the communative property shows you can add or multipy in any order, this means you can add all three of these in a different order and still get the same answer.....For example, you can do $1.25 + $0.80 + $2.75 or you can switch it around and do it in another way

Linda knitted 1/6 of a sweater on Friday and 2/9 of the sweater on Saturday. On Sunday she knitted 1/2 of the remaining sweater.
sladkih [1.3K]
This is pretty simple. All you have to do is make the first and second fraction share a denominator by multiplying them by each other.

6 <span>• 9 = 54

Then multiply each numerator by the opposing denominator.

1 </span><span>• 9 = 9

2 </span><span>• 6 = 12

Here are the new fractions:

9/54

12/54

Now add the 9 and 12 together.

9 + 12 = 21

The complete fraction:

21/54

Subtract 21 from 54 so you can get the remainder of the sweater.

54 - 21 = 33

This is the remainder fraction:

33/54

Can you simplify this? Yes, of course! They can both be divided by 3!

11/18

That is the remainder of the sweater. But you still have to divide it in half! After all, Linda only knitted half of the remaining sweater. Dividing it in half can be done just by multiplying the denominator by 2.

11/36

That should be your answer! Apologies if I got something wrong.</span>
