(4x28)+64
112+64
176
Rounded to the nearest ten it would be 180
Which of the sets of ordered pairs represents a function? (1 point) A = {(2, 7), (1, −5), (7, 2), (2, −9)} B = {(5, 3), (−2, −9)
Neporo4naja [7]
Answer:
its B
Step-by-step explanation:
i was taught to do functions by lining up the xs on one side and the ys on the other(if they repeat only put the number once) then draw lines to the pairs. no x value can have two y values.
Answer:
The answer to your question is 2 seconds
Step-by-step explanation:
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.
