Answer:

y=-9

Step-by-step explanation:

The given function is

g(x)=x^{2} -10x+16

As you can notice, this is a quadratic function. That means its graphic behaviour is a parabola.

So, a parabola has a minimum or maximum, in either case, that point is the vertex. That means we need to find the vertex of this function and its vertical coordinate will be the minimum.

The vertex has coordinates of V(h,k), where h=-\frac{b}{2a}, and a=1, b=-10, c=16.

Replacing each value, we have

h=-\frac{b}{2a}=-\frac{-10}{2(1)}=5

The other coordinate is defined as k=f(h), that is, we need to replace the number 5 in the function to obtain k

g(x)=x^{2} -10x+16\\g(5)=(5)^{2} -10(5)+16=25-50+16=-9

Therefore, the minimum is at y=-9

Which of the following best defines the quantities that should be measured to find Andy's driving speed? The quantity of time me
chubhunter [2.5K]

The quantity of distance measures in miles depends on the quantity of time measured in hours. is your best choice.

The quantity of time is an independent variable, as it continues to go no matter how much you travel, and so it is the independent.

The quantity of distance depends on your speed and time, and because it depends on these two factors, it is the dependent.

hope this helps

Darya [45]
<h3>Given</h3>

A = 2k² -k -15

L = k² -9

<h3>Find</h3>

A/L

<h3>Solution</h3>

\displaystyle\frac{A}{L}=\frac{2k^2-k-15}{k^2-9}=\frac{(k-3)(2k+5)}{(k-3)(k+3)}\\\\=\frac{2k+5}{k+3}
