Determine a and k so the given points are on the graph of the function.
pshichka [43]

Step-by-step explanation:

Explanation:

Because

(2,6) is in the function, we can plug

6 as y

and

2 as x.

From that we get

6=a(2−1)2+k

6=a+k

Same for the next point:

12=a(3−1)2+k

12=22a+k

12=4a+k

Now we have this system of equations to solve:

a+k=6

4a+k=12

Solving it leads to the conclusion that

a=2,k=4 .

Enter the correct value so that each expression is a perfect square trinomial
myrzilka [38]

Answer:

Step-by-step explanation:

1). x² - 10x + a²

  By using the formula of (a - b)² = a² - 2ab + b²

  x² - 2(5)x + a²

  Therefore, for a perfect square of the expression a should be equal to 5.

  Therefore, (x² - 10x + 25) will be the answer.

2). x² + 2ax + 36

  = x² + 2(a)x + 6²

  For a perfect square of the given expression value of a should be 6.

   x² + 2(a)x + 6² = x² + 2(6)x + 6²

                           = (x + 6)²

  Therefore, x² + 12x + 36 will be the answer.

3). x^{2}+\frac{1}{2}x+a^2

    x^{2}+2(\frac{1}{4})x+a^2

   To make this expression a perfect square,

   a² = (\frac{1}{4})^2

   x^{2}+2(\frac{1}{4})x+(\frac{1}{4})^2 = (x+\frac{1}{4})^2

  Therefore, the missing number will be \frac{1}{16}.
