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
The formula is y2-y1 divided by x2-x1 So now-5+7divided by -2+1 =2/-1= -2
Answer:
$2.15
The rose-buying public still encounters a wide variety in pricing - anything from $10 or under for a dozen red roses at the local corner store to $20 at the supermarket, to more than $90 at a high-end florist
Adam descends 5 feet Multiply 5 by four and then you get 30 feet
Turn the percentage into a decimal.
40% = 40÷100 = 0.4
Then multiply it with your no.
36x0.4 = 14.4
