The science club at Jefferson High School is performing an experiment. They want to see if they can design a case that will prevent an egg from breaking when it is dropped from the
roof of the school. The egg, safe in its case, is tossed into the air with an initial velocity of 5
meters per second from a height of 8 meters. The equation h(t) = -4.9t? + 5t + 8 models
the height of the egg in meters after t seconds.
About how many seconds does it take for the egg to hit the ground?

8y^50

step-by-step explanation:

answer:

probably the same as it is today since you did not eat the corn dogs yet

step-by-step explanation:

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
