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:
650^9
power gets added when base is same

Answer:
The linear equation is the equation of straight line. where m is the slope of the line and c is the y-intercept. Thus, the y-intercept is expressed as (0, c). That is where the graph intercepts the y-axis (thus, the x value would be 0).
