H=3+14t-5t^2 What is its maximum height

Mathematics
1 answer:
timurjin [86]3 years ago

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

x_{vertex} = - \frac{b}{2a}

h = 3 + 14t - 5t² ← is in standard form

with a = - 5 and b = 14, thus

x_{vertex} = - \frac{14}{-10} = 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

12 points! The interior angles formed by the sides of a hexagon have measures that some to 720°. What is the measure of angle F?
statuscvo [17]
Sum would be equal to 720.
so, x-60 + x-40 + 130 + 120 + 110 + x-20 = 720
3x + 240 = 720
3x = 720 - 240
x = 480/3
x = 160 

Angle F = x-20 = 160 - 20 = 140

In short, Your Answer would be 140

Hope this helps!
