Hello!</h2>
The answer is:
The ball will hit the ground after
<h2>
Why?</h2>
Since we are given a quadratic function, we can calculate the roots (zeroes) using the quadratic formula. We must take into consideration that we are talking about time, it means that we should only consider positive values.
So,
We are given the function:
Where,
Then, substituting it into the quadratic equation, we have:
Since negative time does not exists, the ball will hit the ground after:
Have a nice day!
1/10*344
=344/10
=34.4
We will move the decimal to the left side in case of division.
Equation
Total = movies plus songs.
Givens
Total = 100
Movies = 48.4
Songs Cost = x
Number of Songs = 40
Solve
100 = 48.4 + 40x Subtract 48.4 from both sides.
100 - 48.4 = 40x
51.6 = 40x Divide by 40
51.6 / 40 = x
1.29 = x
Conclusion
Each song cost $1.29
