What is the vertex of the quadratic function f(x) = (x-8)(x - 2)?

Mathematics

Answer:

The vertex is at (5, -9)

Step-by-step explanation:

The vertex is halfway between the zeros

f(x) = (x-8)(x - 2)

0  = (x-8)(x - 2)

x=8 and x=2 are the two zeros

(8+2)/2 = 10/2 = 5

The x coordinate is at 5

The y coordinate is found by substituting the x coordinate into the function

f(5) = (5-8)(5 - 2) = -3 (3) = -9

The vertex is at (5, -9)

I NEED HELP WITH NUMBER 4​
weeeeeb [17]

Answer:

4.5 inches

Step-by-step explanation:

To find the height in inches of the model, you need to change the ration into a fraction:

\frac{1}{50}

Then try to figure out the value of the denominator in terms of the ratio:

\frac{1}{50} =\frac{x}{725}

In this equation we need to figure out how much the denominator of the fraction is changing by, by dividing 725 by 50. Then, multiply that by one:

4.5
