Step-by-step explanation:
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).
I'm not amazing at fractions but it equals:
1/3 x4= 4/3
so 1 1/3 as mixed fraction

Hello!
To calculate the sale price of the coat, we can simply multiply 150 by .40, then subtract the product from 150.
150 × .40 = 60
150 - 60 = 90
The sale price of the coat is $90.
