Answer:
12.8
Step-by-step explanation:
Given a parabola in standard form , ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
h = 3 + 14t - 5t² ← is in standard form
with a = - 5 and b = 14, thus
= -
= 1.4
Substitute t = 1.4 into h for maximum height
h = 3 + 14(1.4) - 5(1.4)²
= 3 + 19.6 - 9.8 = 12.8
Answer:
15.5 quarts
Step-by-step explanation:
1.5 +8 + 4 + 2
there is need to convert the measures that are not in quarts to quarts
1 gallon = 4 quarts : 2 x 4 = 8 quarts
1 cup = 0.25 quarts : 0,25 x 8 = 2 quarts
1 pint = 0.5 quarts : 0.5 x 3 = 1.5 quarts
Total quarts = 1.5 +8 + 4 + 2 = 15.5 quarts
