Answer:
Horizontal distance, d = 9.146
Step-by-step explanation:
The given function is
The horizontal distance, d, is the distance on ground. So, set f(d) = 0.
That is, a height of zero which becomes the ground level.
Using the quadratic formula:
Thus, the ball is in air between d=-0.146 to d=9.146.
Since the distance can not be negative, the ball remains in the air between d = 0 to d = 9.146.
Therefore d = 9.146
Answer:
10a = 30
Step-by-step explanation:
By using elimination:
4a + 2z = 10
-2(3a + z) = -2(-10)
4a + 2z = 10
6a - 2z = 20
2z and -2z cancel out
10a = 30
a = 3
They are asking for 10a, so 10 (3) = 30.
Since there are 43560 feet in an acre, 285 feet is 0.654% of an acre.
Hope this helps!
