Answer: Option D

$t_{max} =19\ s$

Step-by-step explanation:

Note that the projectile height as a function of time is given by the quadratic equation

$h = -12t ^ 2 + 456t$

To find the maximum height of the projectile we must find the maximum value of the quadratic function.

By definition the maximum value of a quadratic equation of the form

$at ^ 2 + bt + c$ is located on the vertex of the parabola:

$t_{max}= -\frac{b}{2a}$

Where $a$

In this case the equation is: $h = -12t ^ 2 + 456t$

Then

$a=-12\\b=456\\c=0$

So:

$t_{max} = -\frac{456}{2*(-12)}$

$t_{max} =19\ s$

ROUND 258,177 TO THE NEAREST HUNDRED THOUSAND

Galina-37 [17]

258,177 to the NEAREST HUNDRED THOUSAND is 258,000 and nothing else...

If this number was 275,550, the NEAREST HUNDRED THOUSAND would've been 276,000 because of the last three digits in this number...
