Answer: 745
Step-by-step explanation: if there were initialy 80 books and its increasing by 25% every month, for month 1 we have:
25% = 0,25
increase is 1+0.25
M1 = 80.(1+0.25)¹ = 80.1.25 = 100
M10 = 80 (1+0.25)¹⁰ = 80. 9.313225 = 745.05 (end of the month)

Data
function y = -14x² + 56x
maximum height = ?
Process
1.- Find the derivative of the function
y' = -28x + 56
2.- Equal to zero the result
-28x + 56 = 0
3.- Solve for x
-28x = - 56
x = -56/-28
x = 2
4.- Conclusion
It takes to the ball 2 seconds to reach the maximum height.
Answer:
14 headphones
Step-by-step explanation:
Use algebraic manipulation. Let x be the number of headphones sold this week:
89 = x + (3x + 5)
Combine like terms:
89 = 4x + 5
Get the x's on one side:
84 = 6x
Divide:
14 = x
So, Veronica sold 14 headphones this week.
