Complete the square of y^2 + 10y to answer this question.
x=y^2 + 10y + 22 becomes x = <em>y^2 + 10y + 100</em> - 100 + 22, or
x = (y+10)^2 - 78
Comparing this result to the generic form x = a(y-k)^2 + h, we see that
h = -78 and k = -10.
Then the vertex of this parabola is at (-78, -10).
Answer:24 + 24 = 48
you multiply the lenth and with for each of the rectangles
![5x^2+2x-1=0](https://tex.z-dn.net/?f=5x%5E2%2B2x-1%3D0)
Delta equation is:
![\Delta =\frac{-b\pm\sqrt(b^2-4ac)}{2a}](https://tex.z-dn.net/?f=%5CDelta%20%3D%5Cfrac%7B-b%5Cpm%5Csqrt%28b%5E2-4ac%29%7D%7B2a%7D)
but we are interested in
![b^2-4ac](https://tex.z-dn.net/?f=b%5E2-4ac)
because it determines the discriminant
![5^2-4*2*(-1)=25+8=33](https://tex.z-dn.net/?f=5%5E2-4%2A2%2A%28-1%29%3D25%2B8%3D33)
![33>0](https://tex.z-dn.net/?f=33%3E0)
which means that discriminant is positive :)
Answer:
The Answer is 4.79
Step-by-step explanation:
All you have to do Divide 33.53 by 7 then you would get 4.79
I say divide because they want to know how much it one gallon of milk costs So that is why you have to divide
