Answer:
<em>t = 5 seconds</em>
Step-by-step explanation:
We must solve the equation of movement of the ball as a function of time in seconds.
We must find how many seconds it takes until the ball touches the ground. When the ball touches the ground, the height b (t) = 0
Then we equate the equation to zero and solve for t.
Use the quadratic formula.
Where
We take the positive solution
<em>t = 5 seconds</em>

Step-by-step explanation:
Answer: $54.35
Step-by-step explanation:
If each one of the 15 students raises the same amount, let's define this amount by the variable X, then the total amount they will collect is 15 times X, or:
15*X
And the minimum amount they need to collect is $800
Then we will have the inequality:
15*X ≥ $800
Now we can divide both sides by 15 to get the minimum amount that each student needs to raise:
(15*X)/15 ≥ $800/15
X ≥ $54.33...
Where we should round up the right number to $54.35, because we can not have a $0.0333... and if we round down, they would collect less than $800.
Then the inequality is:
X ≥ $54.35
This means that the minimum amount that each one of the 15 students needs to collect is $54.35
Answer:
