Hitman42 [59]

Answer: \dfrac{1}{14}

Step-by-step explanation:

Given, A pizza is to be cut into halves.

Since half is represented by \dfrac12 .

So each piece is now \dfrac12 of the original.

if each of these halves is to be cut into sevenths, then the fraction of  final pieces would be: \dfrac{1}{2}\times\dfrac{1}{7}=\dfrac{1}{14} or we can say each half is divides into 7 pieces since there are two halves, so there will be 2 x 7 = 14 peices.

And the fraction of the pizza is each of the final pieces = \dfrac{1}{14} .

Which equation is equivalent to the formula below? <br> Y = A ( X - H) ^2 + K
frozen [14]

Answer:

<em>B. a = y - k/(x-h)² </em>

Step-by-step explanation:

Given the expression y = a (x-h)² + k

First make  a the subject of the formula

Subtract k from both sides

y = a (x-h)² + k

y- k = a (x-h)² + k - k

y - k = a (x-h)²

Divide through by (x-h)²

y - k/(x-h)²  = a

a = y - k/(x-h)²

Hence option B is correct
