How is this equation completed? I cannot find any examples in the book.
djverab [1.8K]

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

Pls help being timed
Trava [24]
If you find the least common denominator, that is 143. Then, you convert 2/13=22/143 and 1/11=13/143. Next, subtract 22/143-13/143=9/143 which is B

Please learn your fractions :/ they’ll be useful for the future, trust me. If you need further help to understand, idk if there is a PM feature here but if there is feel free. But I have answered 3 fraction questions for you within this hour and it’s under the high school level category??? Thank you and have a nice night.
