The best statement that compares the length of time each ball is in the air is seen in the second option.
<h3>What is
the function of a quadratic equation?</h3>
A quadratic function follows the condition: f(x) = ax² + bx + c. Here (a, b, and c) are real numbers and a ≠ 0.
From the given information:
- The function f(t) = -16t² +64t + 5 models the height of a ball
Where;
- time (t) ⇒ seconds
- height (h) ⇒ feet
The table given is as follows:
Time (in seconds) height, g(t) in feet
0 4
1 36
2 36
3 4
From the table, when t = 0, the function becomes:
f(t) = -16t² +64t + 5
f(t) = -16(0)² + 64(0) + 5
f(t) = 5
Therefore, we can conclude that the best statement that compares the ball is: f(t) is in the air for about 5 seconds, and the ball represented by g(t) is in the air for about 3 seconds.

Answer:
The numbers are 2 and 7.
Step-by-step explanation:
If x and y are the 2 numbers:
x + y = 9
x - y = 5 Adding the 2 equations
2x + 0 = 14
x = 7.
Plug this into the first equation:
7 + y = 9
y = 2.
