A) If you have 12 dogs and cats (I assume 12 in total) and divide those by two, you get six dogs and six cats. It has to be more dogs than cats, and the sum of those two has to be twelve. So to reach the sum 12, while one number is bigger that the other, the number has to be 7 or more.

Simplify the expression 16*4^-4
Neporo4naja [7]
First, solve the exponent part because it has a higher precedence than multiplication. And we have a negative exponent. Which means we takes the reciprocal of 4 then take to the power of 4.

4^-4 = 1/4^4 = 1/256

Now do the multiplication part.

16 * 1/256 = 1/16

What is the vertex of the function x2 - 6x + 8 = 0?
RUDIKE [14]

<u>Answer: </u>

The vertex of the function \bold{x^{2} -6 x + 8 = 0}is (h,k) = (3 , -1)

<u>Solution: </u>

The vertex form of quadratic equation is generally given as,

f(x) = a(x - h)^{2} + k

Where h,k is the vertex of the parabola.

From question, given that x^{2}-6 x+8=0 .

we have to find the vertex of the function.

Let us first convert the given quadratic equation to vertex form (eqn 1)

x^{2}-6 x+8=0

x^{2}-6 x=-8

By adding “9” on both sides of equation, we get

x^{2}-6 x+9=-8+9

x^{2}-6 x+9=1

By using the identity (a-b)^{2}=a^{2}-2 a b+b^{2} ,the right hand side of above equation becomes,

(x-3)^{2}=1

(x-3)^{2}-1=0

Now,the equation (x-3)^{2}-1=0 is of the vertex form.

By comparing (x-3)^{2}-1=0 with a(x-h)^{2}+k

we get the values of (h,k)

a = 1; h = 3; k = -1

hence the vertex of the function x^{2}-6 x+8=0 is (h,k) = (3 , -1)
