It's saying that on every other stop(with even numbers)you add 2 people, and on all the other stops(odd numbers)you subtract 5 people. Be sure that you start with 18 people on the bus! Keep doing this until there is no more people on the bus!

If an object is projected upward from ground level with an initial velocity of 128 ft per sec, then it's height in feet after t
antoniya [11.8K]

Answer: t= 4 seconds

Maximum height = 256 feet

Step-by-step explanation:

The height of the object projected upwards after t seconds is given by

s(t)=-16t^2+128t.

The expression is a quadratic equation. When this equation is plotted on a graph, height against time, it takes the shape of a parabola whose vertex represents the maximum height attained by the object.

To get the value of t at the maximum height,

t = -b/2a

From the equation,

a = -16

b = 128

t = -128/-2×-16

= -128 /- 32= 4

it will take 4 seconds to reach its maximum height

To find maximum height attained, put t= 4 in the equation

s(t)=-16t^2+128t

S = -16× 4^2 + 128×4

S = -256+512

S = 256 feet
