I think the answer is 3/2 but i am not sure
7.75 pounds of seed are needed per acre
The projectile's horizontal and vertical positions at time 
are given by
where 
. Solve 
for the time it takes for the projectile to reach the ground:
In this time, the projectile will have traveled horizontally a distance of
The projectile's horizontal and vertical velocities are given by
At the time the projectile hits the ground, its velocity vector has horizontal component approx. 176.77 m/s and vertical component approx. -178.43 m/s, which corresponds to a speed of about 
.
Answer:
-61/4
Step-by-step explanation:
-1/2 + x = - 21/4 - 23/4 - 19/4
-1/2 + x = -(21+23+19)/4
x = -63/4 + 1/2
x= -63/4 + 2/4
x = -61/4
Hope that helps, tell me if you need further explanation. =)
A. The slope is 25 and it is the rate of change per month. You will pay this additional amount if you go to the gym every month.
b. The y-intercept is 50. This amount is the constant and does not change since it is a one time fee for the year.
