Answer:
The quantity of total serving soup does restaurant has = T = 2 liters .
Step-by-step explanation:
Given as :
The quantity of large serving soup = liters
The total quantity of soup does restaurant has = 3 liters
Let the quantity of total serving soup does restaurant has = T liters
So, According to question
The quantity of total serving soup does restaurant has = The quantity of large serving soup × total quantity of soup does restaurant has
Or, T = × 3
Or, T =
Or, T =
∴ T = 2 liters
So, quantity of total serving soup does restaurant has = T = 2 liters
Hence,The quantity of total serving soup does restaurant has = T = 2 liters . Answer
9514 1404 393
Answer:
10. (x, y) = (-3/8, 2 9/16)
11. k = -1
Step-by-step explanation:
10. The value of x at the vertex is ...
x = -b/(2a)
x = -(-3)/(2(-4)) = -3/8
The corresponding value of y is ...
y = 2 +(-3/8)(-3 +(-3/8)(-4)) = 2 +(-3/8)(-3/2) = 2 +(9/16)
The vertex is (x, y) = (-3/8, 2 9/16).

11. The discriminant is zero when the roots are equal.
b² -4ac = 0
(k-1)² -4(1)(-k) = 0
k² -2k +1 +4k = 0
k² +2k +1 = 0 . . . . . collect terms
(k +1)² = 0 . . . . . . . . write as a square
