Answer:
Therefore the ball travel 102.92 feet horizontally before hitting the ground
Step-by-step explanation:
Given that, the path of a baseball, hit 3 feet above ground, is modeled by the function

where f(x) represents the vertical height of the ball in feet(Assume) and x is the horizontal distance in feet(Assume) .
When the ball hits the ground, then the vertically distance of the ball will be zero, i.e f(x)=0

[Applying quadratic formula
, here a = -0.001, b=1 and c=3]


Therefore the ball travel 102.92 feet horizontally before hitting the ground.

Answer:
Step-by-step explanation:
1) Each of the ratios can be reduced to 1 : 5, Since both can be reduced to the same ratio, the do form a proportion.
4 : 20 = 1 : 5
6 : 30 = 1 : 5
__
2) The first ratio can be reduced to 1/2. The second ratio is not 1/2 and cannot be reduced. Since they are different ratios, they do not form a proportion.
9/18 = 1/2
3/8 = 3/8
YES if you simplify 15:10 by 5 since they can both be divided by 5 the ratio becomes 3:2
