Answer:
t = 2.5 s
Step-by-step explanation:
Suppose you have a water-balloon launcher. The balloon is 3 ft high when it leaves the launcher. Its equation is :

The above equation is a quadratic equation. The general equation is :

Here, a = 16, b = 38.8 and c = 3
The solution of quadratic equation is given by :

So, at t = 2.5 s the balloon is in air.
How many 2/5's fit into 44
2/5 times x=44
multiply both sides by 5/2 to clea fraciton (5/2 times 2/5=10/10=1)
x=220/2
x=110
will support for 110 days
Answer:
The answer is B: 1125
Step-by-step explanation:
I divided it for you and it is the only answer that did not have a decimal.
If they have a different slope they are intersecting lines. If they have the same slope and the same y-intercept they are coinciding lines...
y=4x, m=4, b=0
3x+2y=10
2y=-3x+10
y=-1.5x+5, m=-1.5, b=5
Since this has a different slope they are intersecting lines...
