50 inches 4/5*x=40
x=40/(4/5)
x=40*5/4=200/4=50 x=50 inches
The easiest way to find the vertex is to convert this standard form equation into vertex form, which is y = a(x - h)^2 + k.
Firstly, put x^2 - 10x into parentheses: y = (x^2 - 10x) + 30
Next, we want to make what's inside the parentheses a perfect square. To do that, we need to divide the x coefficient by 2 and square it. In this case, the result is 25. Add 25 inside the parentheses and subtract 25 outside of the parentheses: y = (x^2 - 10x + 25) + 30 - 25
Next, factor what's inside the parentheses and combine like terms outside of the parentheses, and your vertex form is: y = (x - 5)^2 + 5.
Now going back to the formula of the vertex form, y = a(x - h)^2 + k, the vertex is (h,k). Using our vertex equation, we can see that the vertex is (5,5).

Answer:
5000 and 100
Step-by-step explanation:
Answer:
you need to find the vertex, y-intercept, x-intercept, etc in order to create the equation.
Step-by-step explanation:
standard form for quadratic equations should look like this:
f(x)= ax^2+bx+c
(The graph is really blurry, try posting just the graph so I can see it closer if you still need help setting up the equation.)
