Find the Parabola's equation and express the equation as an inequality.
Vertex = (0, -5)
Equation
(x- h) ² = 4p(y - k)
x² = y + 5
y = x² - 5
But, we need the area upper the parabola, then
y ≥ x² - 5
Answer:
a = 3, b = -1, c = 10
Step-by-step explanation:
Let the three numbers be a, b and c.
Equation 1: a + b + c = 12
Equation 2: a + 2b + 3c = 31
Equation 3: 9b + c = 1
Equation 2 - Equation 1:
Equation 4: b + 2c = 19
Equation 3 times by the number 2
Equation 5: 18b + 2c = 2
Equation 5 - Equation 4
17b = -17
b = -1
Substitute into Equation 4:
2c - 1 = 19
2c = 20
c = 10
Substitute into Equation 1:
a + b + c = 12
a - 1 + 10 = 12
a = 3
2 1/3 * 8 = 16 8/3 or 18 2/3 inches in 8 days.
