A football is punted from a height of 3.5 feet about the ground with an initial velocity of 45 feet per second. This situation can be represented by the function (t)=-16t²+45t+3.5, where t is the number of seconds elapsed since the football was kicked. If the football is caught at a height of 5.5ft on the ball’s descent, how long was the football in the air? Round to the nearest hundredth.

it’s the first one your welcome

none.

step-by-step explanation:

m

m1=5

b

−

1

b=-1

find the slope and y-intercept of the second equation.

b=-6

compare the slopes

m of the two equations.

m

=

0

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
