ratio 2:3
2 + 3 = 5
185 / 5 = 37
so
37 x 2 = 74
37 x 3 = 111
Answer
185 g in the ratio 2:3 = 74: 111
If the parabola has y = -4 at both x = 2 and x = 3, then since a parabola is symmetric, its axis of symmetry must be between x = 2 and x = 3, or at x = 5/2. Our general equation can then be:
y = a(x - 5/2)^2 + k
Substitute (1, -2): -2 = a(-3/2)^2 + k
-2 = 9a/4 + k
Substitute (2, -4): -4 = a(-1/2)^2 + k
-4 = a/4 + k
Subtracting: 2 = 2a, so a = 1. Substituting back gives k = -17/4.
So the equation is y = (x - 5/2)^2 - 17/4
Expanding: y = x^2 - 5x + 25/4 - 17/4
y = x^2 - 5x + 2 (This is the standard form.)
Answer:
B
Step-by-step explanation:
The zeros of the quadratic occur at x = 0 and x = 6
Thus the factors are x and x - 6
