Answer:
3 seconds
Step-by-step explanation:
We have to give us the following function h (t) = - 16 * t ^ 2 + 48 * t + 3
Now, they tell us that the height is 3 feet, therefore replacing that value we have left:
3 = -16 * t ^ 2 + 48 * t + 3, operating cancels 3. And it would be:
-16 * t ^ 2 + 48 * t = 0
Removing common factor -16 * t, it would be:
(-16 * t) * (t - 3) = 0
We have two solutions:
-16 * t = 0 ---> t = 0
t - 3 = 0 ---> t = 3
Because the time cannot be 0 seconds, the time it would take the ball in the air is 3 seconds.

Answer:
7
Step-by-step explanation:
by similarity of traingles Δxuw and Δxyz
xu/xy = uw/yz
given xu+uy=xy and xu=uy
2(xu)=xy
xy=2(uy)
=>5x+4=2(4x-1)
=>5x+4=8x-2
=>3x=6
=>x=2
=>given length of uw=>4x-1=4(2)-1=7
the first one! please let me know it its wrong
