A firework is shot into the air, but it malfunctions and does not explode. The firework’s height below or above sea level in meters, h, as a function of the time in seconds ,t, since it was shot is h(t)-4.9t^2+29.4t-40.1 The maximum height of the firework is (blank) sea level.

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.

many reason,

step-by-step explanation:

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
