If the arrow is in the air, then when it hits the ground, h(t)=0. So:
0=-16t²+63t+4
16t²-63t-4=0
(16t+1)(t-4)=0
t= -1/16 or 4
Using the positive result of 4, we get t=4 seconds as the time the arrow was in the air

Answer:
That is, the number of rows of stitches Buddy knitted is 42 rows.
Step-by-step explanation:
With the question, we note that the size of 3.5 rows of stitch = 0.5 inches
The size of Buddy = 6 inches
The number of rows of stitch required to make 6 inches is given by;
0.5 in = 3.5 rows
1 in = 3.5 ÷ 0.5 or 7 rows
Therefore, 6 inches is given by,
7 rows/inch ×6 inches = 42 rows
That is, the number of rows of stitches Buddy knitted = 42 rows.
