The ball takes approximately a time of 2.041 seconds to reach its maximum height.
<h3>What time does the ball take to reach maximum height?</h3>
The height of the ball as a function of time is modelled by a <em>quadratic</em> equation, the required information can be found by transforming the expression into <em>vertex</em> form:
h = - 4.9 · t² + 20 · t + 12
h = - 4.9 · (t² - 4.082 · t - 2.449)
h + (- 4.9) · (6.615) = - 4.9 · (t² - 4.082 · t + 4.166)
h - 32.414 = - 4.9 · (t - 2.041)²
The ball takes approximately a time of 2.041 seconds to reach its maximum height.

Step-by-step explanation:
Because 2400 = 24 * 100, we can divide 48 by 2 to find the answer quicker:
3.84/2 = 1.92
1.92 * 100 = 192

Step-by-step explanation:
The graph has distanced someone side and frequency density a people on the other side So therefore you go to the 30 mark look up with the nearest number is on the frequency and you find that frequency connects with the 30 at 5
